った。BACKGROUND TECHNOLOGY In general, in a scroll type compressor, lubrication and sealing properties at the layered contact portion between a movable scroll member and a fixed scroll member are a problem. An oil guide passage 21C is provided on the end face of the spiral part 21b to the base plate 21a and the spiral part 21b of the scroll member 21, and oil is supplied from the oil storage part of the discharge chamber to the front two oil guide passages 21c. Some devices are designed to improve the lubrication and sealing properties of the end surface of the spiral portion 21b. Further, as shown in FIG. 8, an oil guide passage 220 is formed in the base plate 22a and the spiral portion 22b of the fixed scroll member 22 in the same manner as the oil guide passage 21c, to provide lubrication and lubrication at the end face of the spiral portion 22b. Some were designed to improve sealing performance. Japanese Patent Publication No. 56-14338
However, in this conventional lubrication structure, the openings of the oil guide passages 21c and 22c are always covered by the substrate of the mating scroll member, so the amount of oil supplied is small and the lubrication and sealing properties are insufficient. Not only is there a spiral part 21
It is also insufficient in terms of improving the sealing performance at the contact area between 22b and 22b (at the boundary with the preceding compression chamber), and there is a defect in that the volumetric efficiency cannot be increased.
