The conventional electric suction spout for carpets has a tuck that allows for removal from the wall edge, and an auxiliary rotating brush is placed on the coaxial path of the main rotating brush body, and the end surface of the auxiliary rotating brush and the side wall of the suction body are connected to each other. Although the structure is such that the gap is small and the area that can be removed is as wide as possible, if long fibers such as lint get tangled with the brush, the lint will gather at the center of the end surface of the auxiliary rotating brush as the auxiliary rotating brush rotates. However, there were drawbacks such as thread accumulation between the main body side wall, increased rotational load loss, and decreased lifespan due to oil draining of the bearing due to lower rotational speed and heat generation.[Invention [Problems to be Solved] The present invention provides a plurality of grooves on the outer circumference of the auxiliary rotating brush as a means for fitting and fixing an inclusion made of a substantially conical elastic member to the end of the auxiliary rotating brush. At the same time, protrusions facing the grooves are provided on the inner circumference of the inclusion, and by fitting them into each other, they are held firmly in place to prevent out-of-phase rotation of the auxiliary rotating brush and the inclusion, curling, etc. Therefore, an object of the present invention is to provide a fitting structure that eliminates the gap by inserting an inclusion made of an elastic material between the end face of the auxiliary rotating brush and the side wall face of the main body, thereby reducing the load caused by the intrusion of lint that conventionally occurs in the gap. An electric type for carpets that eliminates problems such as a decrease in rotational speed due to increase in rotation speed, allows the rotating brush and inclusions to rotate without any problems due to sliding, and prevents lint from entering due to inclusions at all times. [Means for solving the problems] Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 5 shows another embodiment of the present invention.1. The difference from FIG. 1 is that the mounting structure of the auxiliary rotary brush 4 and the seal body 20 is reversed, and the auxiliary rotary brush 4 and the outer circumference 26 of the auxiliary rotary brush 4 are different from each other.
Four projections 34 are provided at the base of the seal body 20, and mounting grooves 36 are provided at four locations at the base 21 of the seal body 20 so as to fit with the projections 34, thereby securing the seal body 20 firmly. The functional effects of this embodiment are similar to those shown in FIG. 1, but the mounting structure of the seal body 2'0 is simple and can be easily mounted. As described above, as a means for attaching a substantially cone-shaped seal body made of an elastic material such as rubber to the end of the auxiliary rotating brush, projections or ring-shaped parts are attached to multiple parts of the inner periphery of the auxiliary rotating brush side of the seal body. The protrusions are provided on the outer circumference of the auxiliary rotating brush, and the grooves are provided all around or in a plurality of grooves on the outer circumference of the auxiliary rotating brush in the same way as described above, and the brushes are fitted and fixed to each other, so that the dust-proofing effect against lint, etc. as a sealing body can always be maintained in the best condition and is stable. It has the effect of absorbing dust from the carpet.
