PURPOSE:To reduce vibration of a compressor by preventing a blade spring from excessively pushing a blade at normal operation while attaching a shape storing alloy to the blade spring and adjusting the blade pushing force caused by said spring utilizing the characteristic change of this alloy which follows the temperature change. CONSTITUTION:Lifting force by a blade spring stopper 13 caused by the characteristic change as illustrated of a shape storing alloy 15 provided in parallel with a blade spring 7, which follows the temperature change is reduced in an initial operation, since the inside of a blade 6 pushing hole 12 is in a lower temperature state, and strong pushing force by the blade spring 7 is applied to the blade 6. Accordingly, the blade 6 is forcedly pressed down onto a roller 2 to prevent any leakage from a compression chamber to a suction chamber 9 as well as blade sound generation. And, the roller 2 is not excessively pressed, at a normal operation in contrast with the initial operation because of the above described characteristics, thus enabling any vibration and excessive power consumption to be reduced. |
