Abstract

PURPOSE:To prevent the generation of noise from the piping by holding the circular outer periphery of a bearing or the like inside an enclosed case through plural rollers, and providing a bellows-form vibration absorbing member between the part fixed to the enclosed case and the pressing-in part to the compressor side, of a suction pipe. CONSTITUTION:After numerous balls 19 are accomodated rollable in a ring-form groove 18a formed at the circular outer periphery of a bearing 18, the bearing 18 is held by a ring form shell 21 which is fixed to the inner peripheral surface of an enclosed case 2, and a crankshaft 5 driven by a motor M is held rotatable to the bearing 18. To an eccentric member of the crankshaft 5, a piston 6 is geared rotatable, and the end of the crankshaft 5 is held by a bearing 9. And an end of a suction pipe 22 is pressed in and fixed to the bearing 9, while a part of the suction pipe 22 is welded and fixed to the enclosed case 2. And a vibration absorbing member 22a of a bellows-form is formed between the pressing-in part and the weld, to prevent the generation of noise owing to the vibration of the piping.
