A torque limiter device for limiting a torque transmitted between a power source-side member and an output-side member is disclosed. The torque limiter device includes a cover, a friction disc and an urging member. The cover includes a coupling portion, a tubular portion and a support portion. The coupling portion is coupled to the power source-side member. The tubular portion axially extends from the coupling portion. The support portion extends from the tubular portion to an inner peripheral side. The friction disc is accommodated in an inner peripheral space of the tubular portion of the cover, and is pressed toward the power source-side member. The urging member is supported by the support portion of the cover, and urges the friction disc toward the power source-side member.

A clutch device includes a clutch hub radially inward of a clutch rotational axis on a hub side of the device, a clutch flange radially outward on a flange side of the device, a spring device through which the hub and flange sides support each other in the circumferential direction in a resilient torque-transmitting manner, the spring device having a spring element that, in the circumferential direction, is supported at opposite ends by first and second support components assigned to the flange and hub, and a stop device through which the hub and flange sides support each other in an interlocking torque-transmitting manner in the circumferential direction when a defined maximum twist angle is reached between the hub and flange sides, wherein the stop device has first and second interlocking elements integrally formed with the first and second support components that interlock when the maximum twist angle is reached.
