Claims

[Scope of utility model registration request]

A pair of scroll members each having a spiral body formed on one side plate are engaged with each other at different angles, and the fluid pocket is sealed between the spiral bodies with the side walls in contact with each other.
) are stacked so as to form one scroll member, and one of the scroll members is moved in a relative circular orbit while preventing rotation, thereby moving the fluid pocket toward the center of the spiral body with a decrease in volume, In a scroll type compressor that performs a unidirectional fluid compression action, a groove along the right wall of the spiral is formed in the end face of the right wall of the spiral protruding from the side plate, and the width is smaller than the width of the groove, and A scroll compressor characterized in that a sealing member having a thickness substantially greater than the depth of the groove is fitted into the groove.
