Claims

[Scope of utility model registration request]

An orbiting side thrust plate rotatably disposed on an end plate of an orbiting scroll that engages with a fixed scroll, and an orbiting side ball retainer fixed to the end plate so as to cover this thrust plate with a small gap therebetween. , a stationary thrust plate rotatably disposed on the inner wall of the housing opposite to the rotating thrust plate, and a stationary ball retainer fixed to the inner wall so as to cover the thrust plate with a slight gap therebetween. and a plurality of ball holding holes drilled in the swing side ball retainer and a plurality of ball holding holes drilled in the stationary side ball retainer with the same diameter, on the same pitch circle, and the same pitch as the ball holding holes. In a scroll compressor equipped with a rotation prevention mechanism consisting of a plurality of balls held between A scroll compressor characterized in that the gap between the retainer and the retainer is 0.1 mm or less.
