PROBLEM TO BE SOLVED: To provide a rotary machine capable of restraining resonance between a first rotor and a second rotor, and enhancing durability of the rotary machine per se. SOLUTION: A receiving member 42 is fixed to a drive shaft 16 so as to be integrally rotatable, the drive shaft 16 which is rotatably supported by a housing. A pulley 17 is rotatably supported by the housing and is operatively connected to the receiving member 42 in a state where it is disposed at a substantially coaxial position with the receiving member 42. On a power transmission path between the pulley 17 and the receiving member 42, a rubber damper 43 is provided, which damps rotary vibration transmitted from the receiving member 42 to the pulley 17. The pulley 17 has a dynamic damper that restrains the rotary vibration of the pulley 17 by pendulum motions of rollers 46. Stress on bearing members and the like supporting the pulley 17, which is produced due to axial displacement between the pulley 17 and the receiving member 42, is reduced by the rubber damper 43. |
