PROBLEM TO BE SOLVED: To obtain friction torque for controlling damper spring resonance by applying a small pressure force of a friction spring. SOLUTION: In a clutch 1, wherein a driven gear 3 and a clutch member 5 are arranged coaxially and rotatably around a driven axle 9, multiple damper springs 4 to transmit torque of the driven gear 3 to the clutch member 5 are arranged between the driven gear 3 and the clutch member 5 at intervals in a circumferential direction, and a friction spring 20 is provided to push the driven gear 3 to contact with the clutch member 5 in an axial direction to generate friction at contact surfaces 22 of the two 3, 5 so as to control resonance of the damper springs 4, the friction spring 20 and the contact surface 22 are arranged at an outer side of the damper spring 4.
