Torque limiter embedded damper device

A torque limiter embedded damper device provided between a power source-side member and an output-side member, the torque limiter embedded damper device comprising:

• a damper unit coupled to the output-side member;
• and
• a torque limiter unit configured to limit a torque transmitted between the power source-side member and the damper unit, wherein
• the damper unit includes
• a first rotor having a disc shape,
• a second rotor including a flange axially opposed to the first rotor, the second rotor rotatable relative to the first rotor, the second rotor coupled to the output-side member,
• a stopper mechanism configured to restrict an angle of relative rotation between the first rotor and the second rotor to a predetermined angular range, the stopper mechanism including a cutout and a stop pin, the cutout provided in the flange, the cutout extending in a circular-arc shape, the stop pin fixed to the first rotor, the stop pin axially penetrating the cutout, and
• an elastic member configured to elastically couple the first rotor and the second rotor in a rotational direction, and
• the torque limiter unit includes
• a friction plate having an annular shape, the friction plate fixed at an inner peripheral part thereof to an outer peripheral part of either the first rotor or the second rotor by a fixation member, the fixation member fastened in a state of penetrating the cutout of the flange;
• wherein
• the cutout of the stop mechanism is an elongated hole having a circular-arc shape, the elongated hole provided with a protruding portion recessed radially outward from a circumferential part thereof, and
• the fixation member penetrates the elongated hole and the protruding portion.
