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 spring assembly includes a first coil spring and a second coil spring. The second coil spring includes a first winding portion and a second winding portion. The first winding portion includes a plurality of windings from a first winding to at least a second winding. The second winding portion is a portion except for the first winding portion. An outer diameter of each of the plurality of windings of the first winding portion is smaller than an outer diameter of each of at least one winding of the second winding portion. Each of the plurality of windings of the first winding portion includes the substantially same outer diameter.

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 vehicle component positioning structure positions a second component for a vehicle on a first component for the vehicle. The vehicle component positioning structure includes a first hole portion provided in the first component; and a pin member fitted into the first hole portion and protruding from the first hole portion in order to support the second component. A gap is provided between a portion of an inner peripheral surface of the first hole portion and a portion of an outer peripheral surface of the pin member, the portion of an outer peripheral surface of the pin member opposing the portion of the inner peripheral surface of the first hole portion.
