Abstract
A thrust plate disposed between an orbiting scroll member and a bearing for receiving a force axially exerted thereon is provided with a protrusion formed on the same plane as the thrust plate and projected radially inward. The bearing has a thrust plate holder comprising a recess to which the protrusion of the thrust plate fits in, by which the thrust plate is prevented from rotating while being able to move smoothly in an axial direction. Abrasion caused by rotation of the thrust plate is thus prevented, as well as abrasion on outer circumferential parts of the thrust plate can be prevented as a result of the thrust plate is capable of slightly shifting for adjustment to follow up any precessional movement of a thrust load.
