Abstract:
1. A torque limiter configured to limit a torque to be transmitted from an engine-side member to a transmission-side shaft, comprising: a drive member coupled to the engine-side member, the drive member including a friction coupling surface; an input-side plate including a damper mechanism circumferentially elastically coupling the input-side plate and the output-side member; and a transmission torque limiting part configured to limit a torque to be transmitted from the drive member to the transmission-side shaft, with the first and second friction members being interposed and held between the transmission torque limiting part and the friction coupling surface of the drive member, the transmission torque limiting part including a pressure ring pressing the first and second friction members onto the friction coupling surface of the drive member, either the pressure ring or the friction coupling surface of the drive member including a protrusion protruding closer to one of faces of the input-side plate, the protrusion being disposed radial inwards of the first and second friction members.
