The second spring holder is arranged on a second side of the output-side rotor, has a facing side facing the output-side rotor, and has second spring accommodation portions on the facing side each of which accommodates each of the second coiled springs. The input-side sliding contact surface is provided in the second spring holder so as to be in sliding contact with an output-side sliding contact surface of the output-side rotor. The biasing member is provided between the first spring holder and the output-side rotor to press the output-side rotor toward the second spring holder.
