<p>PROBLEM TO BE SOLVED: To suppress vibration and noise caused in slidable operation of a planet plate by interposing a damping elastic body between the inner surface of a supporting body receiving hole and the outer peripheral surface of a planet plate supporting body. SOLUTION: Two rubber O-rings 75 is fit as a damping elastic body around a planet plate supporting body 70 inserted in a supporting body receiving hole 21 formed on a cylinder block 20. The O-rings 75 as the damping elastic body are interposed on two parts which are different in the axial direction of the supporting body receiving hole 21 between the inner surface of the supporting body receiving hole 21 and the outer peripheral surface of the planet plate supporting body 70. The material of the O-ring 75 is, for example, EPDM, H-NBR, OR RBR. Contact interference of the planet plate supporting body 70 circumferential surface and the inner wall of the supporting body receiving hole 21 caused in precession of the plant plate supporting body 70, is absorbed by two rubber made O-rings 75 which are fit around the planet plate supporting body 70 so as to suppress vibration.</p> |
