To improve an absorbing performance in torque variation by reducing hysteresis.

A damper device 30 comprises: a damper spring 35 compressed by a relative rotation of a clutch piston 21 and an operating member 25; a first plate 31 which can be relatively rotated with respect to the clutch piston 21 and the operating member 25 and arranged to be rotatable together with one end of the damper spring 35, and includes a housing recess section 31c housing one end of the damper spring 35; and a second plate 32 which can be relatively rotated with respect to the clutch pin 21 and the operating member 25 and arranged to be rotatable together with the other end the damper spring 35, and includes a housing recess section 32c housing the other end of the damper spring 35.
