<p><P>PROBLEM TO BE SOLVED: To provide a rotary shaft supporting structure for a compressor of a car air-conditioner capable of materializing a long lifetime and low fuel consumption. <P>SOLUTION: The rotary shaft supporting structure for the compressor of the car air-conditioner includes a rotary shaft, and a thrust roller bearing supporting thrust load generated by rotation of the rotary shaft. A retainer 11 provided in the thrust roller bearing includes a plurality of pockets 14 holding rollers, and is a retainer for an annular thrust roller bearing which is not bent in a thickness direction. An outer diameter side and an inner diameter side end surfaces in a radial direction of the retainer 11 include projection parts 18a, 18b projecting in the radial direction in a section surface of the retainer 11 cut by a plane parallel to a rotation axis 20 of the retainer 11 and including the rotation axis 20. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
