PROBLEM TO BE SOLVED: To reduce an abnormal sound caused by the fluctuation of torque to be transmitted. SOLUTION: Out of dampers 14, the 1st elastic modulus k1 (=ΔT/Δθ) of a 1st deformed part 14a on which a normal rotation torque acts is made smaller than the 2nd elastic modulus k2 of a 2nd deformed part 14b on which an inverse rotation torque acts, thereby absorbs the fluctuation of the torque supplied from an engine E/G (driving source). Therefore, the collision between the movable components of a compressor 1 and pulley 10, at the part where a play or clearance is provided, caused by the oscillation of the movable components due to the fluctuation of the supplied torque with a decrease in the delivery capacity is prevented, hence the abnormal sound is reduced as well.
