Claims

[Scope of utility model registration request]

A pair of scroll members each having a spiral body provided on a side plate are stacked one on top of the other so that both spiral bodies are angularly shifted and mesh with each other, and the relative circular orbit of one scroll member with respect to the other scroll member is determined. A scroll type compressor that compresses fluid by moving a fluid pocket formed between the spiral bodies toward the center of the spiral bodies, thereby reducing the volume of the fluid pocket. In the scroll type compressor, at least one of the scroll members has a wear-resistant plate disposed on a side plate on which the spiral body is provided so as to cover between the walls of the spiral body. Scroll type compression characterized in that a step is provided in the center of the side plate surface where the abrasion plate is arranged in a direction that reduces the thickness of the side plate, and a gap is formed between the side plate and the abrasion resistant plate.
