PURPOSE: To prevent contact of a lower bearing with a C-shaped spring as accompanied by eccentric rotation of a shaft, by just additionally providing a recess at a part of the outer circumference of a flange of the lower bearing.
CONSTITUTION: There is provided a recess 18 at a part of the outer circumference of a flange of a lower bearing 12. A valve plate 10 is reciprocated in association with eccentric rotation of a shaft 15, and in cooperation therewith, a C-shaped spring 16 is swung. However, since the lower bearing 12 is provided with the half countersunk recess 18, it is prevented from coming into contact with the C-shaped spring 16. Thus, contact between parts may be prevented. In this manner, it is possible to manufacture a compressor having a greater output with the same series by minimum requisite additional working of parts, thereby causing great economic advantages such as improvement in cost of die, jig, parts, measuring instruments and manufacturing line.
