(effect of embodiment and effect)

Next, the effect and effect to first embodiment are illustrated.Carry out being used for checking effect herein and imitated The experiment of fruit, the result of the test is shown in Fig. 6 and Fig. 8.Experiment is as follows：Omnidirectional loudspeaker is being arranged on to the car of automobile 1 It is set to outside railway carriage or compartment and by front truck door glass 22 and rear car door glass 32 under completely closed state, the loudspeaker is sent sound, make Acoustic pressure is measured with the microphone being arranged in compartment, but these are not shown.Microphone is arranged on corresponding with the head of occupant On position.

It is using curve map that measurement result is shown in Figure 6.Transverse axis in Fig. 6 represents measurement frequency, and the longitudinal axis represents sound pressure level, More moved to the upside of the longitudinal axis, represent that acoustic pressure is higher.Comparative example 1 is expressed as follows described situation：For top glass guide groove 23A, rear corners glass run 23E and the longitudinal glass run 23C of rear side, by by the base end side of interior compartment side sealed lip 41 Portion 41b forward surface 41d and the angle [alpha] of the compartment inner surface 22b formation of front truck door glass 22 are set to 45 degree.Comparative example 2 is represented Angle [alpha] is set to 25 degree of situation.In comparative example 1 and comparative example 2, sound absorption portion 41h is not formed on forward surface 41d, by The smooth face same with glass contact face 41e constitutes forward surface 41d.

It was found from the measurement result shown in Fig. 6, near 2000Hz and more than wider untill 3000Hz to 5000Hz In the range of, the acoustic pressure that angle [alpha] is set in 45 degree of comparative example 1 than angle [alpha] is set to 25 degree of comparative example 2 reduce 2dB~ 3dB or so, can obtain obvious acoustic pressure reducing effect.

Present inventor is had found while angle [alpha] is gradually changed to 90 degree from 15 degree while carried out above-mentioned experiment In the case where angle [alpha] is less than 35 degree and angle [alpha] more than 65 degree in the case of acoustic pressure than angle [alpha] more than 35 degree and 65 Acoustic pressure in the case of below degree is significantly increased.It is therefore preferable that making angle [alpha] more than 35 degree and less than 65 degree.Particularly preferably make Angle [alpha] is more than 40 degree and less than 50 degree.

That is, because angle [alpha] has reached more than 35 degree, therefore, interior compartment side sealing lip is entered through front truck door glass 22 The noise in the R of space between the cardinal extremity sidepiece 41b in portion 41 forward surface 41d and the compartment inner surface 22b of front truck door glass 22 The number of times reflected in the R of the space can be reduced, so that above-mentioned noise is difficult to be exaggerated.Further, since with door glass 22 Angle [alpha] between compartment inner surface is below 65 degree, therefore, it is possible to suppress：Occur in the base end side of interior compartment side sealed lip 41 The reduction of the sound spread out of again to outside compartment through door glass 22 after reflection.Thus, also can be clearly from result of the test Find out：The acoustic pressure of the noise passed in the ear of occupant reduces.

And then, by the way that angle [alpha] is set in into more than 35 degree, so that through front truck door glass 22 towards opposite on the outside of the compartment The incident angle θ of sound incident face 41d is (shown in Figure 4) to be reduced compared to the situation that angle [alpha] for example is set as into 25 degree.By This, towards forward surface 41d, incident acoustic constituents can be reduced at a slant, therefore, front truck door glass 22 can be because of institute through loss The coincidence effect (coincidence effect) of meaning and increase, this also can subtract the acoustic pressure of the noise passed in the ear of occupant It is small.It should be noted that the incident angle θ of sound is to be entered by sound towards the compartment outer surface 22a of front truck door glass 22 Approach axis and the angle of compartment outer surface 22a formation.

It should be noted that from the viewpoint of from Vehicle structure, when door glass 22 rises, according to the dress of car door 2 With deviation, the front end of door glass 22 and cardinal extremity sidepiece 41b forward surface 41d can collide sometimes.Now, if above-mentioned angle α can release the energy produced when collision within 45 degree, then and avoid car door 2 by breakage, therefore be preferred.

In addition, space R shape also can be roughly the same with above-described embodiment in the case of the variation shown in Fig. 5, because And can obtain and the effect of the identical of comparative example 1 and effect.In addition, the effect brought by tail gate glass run 33 and effect Also it is identical with the effect and effect brought by front door glass run 23.

Curve in Fig. 8 represents the difference of the acoustic pressure of embodiments of the invention and comparative example 1, and transverse axis therein represents measurement frequency Rate, the longitudinal axis represents sound pressure level.The structure of embodiment is as follows：Angle [alpha] is being set as on the forward surface 41d of 45 degree of comparative example 1 Form sound absorption portion 41h (reference picture 4).From the measurement result shown in Fig. 8 can it is clearly seen that：With no formation sound absorption portion 41h Comparative example 1 compare, the acoustic pressure of embodiment in the wider scope near 2000Hz untill near 3500Hz frequently compared with Low 1dB of acoustic pressure of example 1 or so, also, in more than 5000Hz region, the acoustic pressure of embodiment is also than low 1dB of comparative example 1 or so. Thus, quietness acoustically is improved.It is preferred that：In angle [alpha] more than 35 degree and in the case of less than 65 degree of scope, Sound absorption portion 41h is formed on forward surface 41d.Further preferably：Angle [alpha] more than 40 degree and less than 50 degree of scope situation Under, sound absorption portion 41h is formed on forward surface 41d.
