Because of the large gap 405, there is a problem that the surface pressure increases and abnormal wear occurs due to the discontinuity of the collar 402 in the circumferential direction. For example, the mating side that comes into contact with the flange portion 402 is abnormally worn, and when the lubrication portion 402 itself has a lubricant layer on its surface, the lubrication material on the surface starts from a desired portion in the V-shaped gap 405. The layer will peel off.
