摘要： A friction generating mechanism of a damper apparatus includes a bushing in contact with an annular friction surface of a spline hub, and a cone spring arranged in a compressed state between a retaining plate and the bushing. A first load support surface of the bushing and a second load support surface of the retaining plate have step portions recessed so as to respectively receive an outer peripheral edge and an inner peripheral edge of the cone spring, when the taper of the cone spring is reversed. The radial positions of boundaries of the step portions are in a relationship of D1>D2, which inhibits the cone spring from being reversed even when an excessive load in the axial direction is input.

摘要： A power transmission device includes an input-side rotary part to which a torque is inputted from an engine, an output-side rotary part, and a damper part. The output-side rotary part includes a first rotor and a second rotor. The first rotor is configured to be rotatable relative to the input-side rotary part. The second rotor is configured to be unitarily rotatable with the first rotor. The second rotor is configured to be rotatable relative to the first rotor when the torque fluctuates with a predetermined magnitude or greater. The damper part is configured to elastically couple the input-side rotary part and the output-side rotary part.

摘要： A flywheel assembly includes a first rotary member, a second rotary member, a first coil spring, a second coil spring, an intermediate plate, a first stopper mechanism and a first contact relief member. The first coil spring is configured to be compressed between the first rotary member and the second rotary member. The second coil spring is configured to be compressed between the first rotary member and the second rotary member and has a stiffness greater than a stiffness of the first coil spring. The intermediate member is engaged with the first coil spring and the second coil spring and couples the first coil spring and the second coil spring in series. The first stopper mechanism is configured to deactivate the first coil spring. The first contact relief member is movably disposed inside the first coil spring and is capable of relieving the contact in the first stopper mechanism during activation of the first coil spring.

摘要： A hysteresis torque generating mechanism includes a first rotor having a slide surface, and a second rotor opposed to the first rotor. The second rotor is configured to slide against the slide surface of the first rotor so as to generate a hysteresis torque. The second rotor includes an initial contact portion and a main friction surface. The initial contact portion is provided to protrude toward the first rotor. The initial contact portion is configured to slide in contact with the slide surface of the first rotor. The main friction surface is configured to slide in contact with the slide surface of the first rotor after abrasion of the initial contact portion.

摘要： A damper device for a vehicle is disposed between a power source and an output-side member in the vehicle. The damper device includes an input-side rotary member, an output-side rotary member, a damper, and an inertia body. The input-side rotary member is coupled to an output end of the power source. The output-side rotary member is coupled to the output-side member. The input-side rotary member and the output-side rotary member are coupled by the damper to be rotatable relatively to each other. The inertia body is coupled to at least one of the input-side rotary member and the output-side rotary member, the inertia body formed by laminating a plurality of plate members.
