Kind Code:
B2
Abstract:
PURPOSE: To fix a fixing scroll without giving it local concentration of stress by providing the fixed scroll, a rotating scroll, a specific block, and a plurality of plate springs, and by storing the fixing scroll and the block to the groove of the block in a sandwiched manner, and whereby fixing them.
CONSTITUTION: A fixing scroll 4a, a rotating scroll 5, and a block 3a, the linear expansion coefficient of which is almost equal to that of the fixing scroll 4a, and which has a groove 3aa on the outer periphery, are provided. A plurality of plate springs 9 to be stored in the groove 3aa of the block, for sandwiching the fixing scroll 4a and the block 3a to be fixed, are provided. After the fixing scroll 4a and the rotating scroll 5 are positioned, and when the fixing scroll 4a and the block 3a are to be fixed, the plate springs 9 are stored in the groove 3aa provided on the outer periphery of the block 3a, and they are sandwiched between the plate springs 9, and are fixed thereby.
