摘要： A thrust roller bearing apparatus is such as to be installed in a hydraulic mechanism to adjust a gap produced between components when they are assembled in the hydraulic mechanism and is configured such that a back side of a race forms an oil pressure chamber in a space produced between the back side of the race and a mating member which the race oppositely faces, so that the race bears a pressure from the oil pressure chamber so as to be displaced axially to thereby carry out the adjustment of the gap.

摘要： A cage includes cage pockets for retaining rollers at plural positions along a circumferential direction of an annular plate. A projection extending in thickness direction of the cage is formed at a central part in the circumferential direction on an inner face of the cage pocket to pivotally support the roller. The projection is provided with a chamfered portion (non-contact portion) formed by chamfering an edge in the thickness direction, and a flat portion (contact portion) that is brought into contact with an opposing central portion in the thickness direction on a roller end face of the roller seated in o the cage pocket. The flat portion has a flat length almost equivalent to a displaceable distance of the cage in the thickness direction thereof.
