PROBLEM TO BE SOLVED: To suppress the vibration of a movable member such as a swing member and a piston during high speed rotation in a compressor.;SOLUTION: The swing member 110 is supported in a swingable manner by a hook type swing support member 114 of universal joint shape in the regulated (impeded) state of rotation around a center line Lo, and the inclined rotation center P1 which is an intersection of a first axis L1 and a second axis L2 is positioned to coincide with the center of gravity of a variable mechanism part comprising a second rotating member 117, the swing member 110, a thrust bearing 111 and a turning member 108. Consequently, such inclined rotation moment as to increase/decrease the inclination angle θ of the swing member 110 (turning member 108) is not structurally generated, while the eccentric amount to the inclined rotation center P1 becomes zero. The generation of large vibration and noise can thereby be prevented even in high speed operation, and durability and silence in high speed operation can be improved.;COPYRIGHT: (C)2004,JPO
