摘要： An output rotary member is coupled to a turbine and rotatable relatively to a clutch portion. First elastic members elastically and rotation-directionally couple the clutch portion and the output rotary member. A dynamic damper device is coupled to any of members forming a power transmission path from the clutch portion to the output rotary member and includes a damper plate having a plurality of circumferentially extending first openings and to be rotated together with the output rotary member. The dynamic damper device also includes inertia members disposed on both axial sides of the damper plate and rotatable relatively to the damper plate, each of the inertia members having circumferentially extending second openings located to oppose the first openings. The dynamic damper device further includes second elastic members accommodated in the first openings and the second openings, the second elastic members elastically coupling the damper plate and the inertia members.

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 damper device includes first and second rotors, and an elastic coupling part elastically coupling the two rotors. The elastic coupling part includes first and second elastic members initially disposed in a compressed state in a neutral condition without relative rotation between the two rotors. The first elastic member is transitioned from the compressed state to a free state and then further compressed when torsion of the first rotor with respect to the second rotor is caused from the neutral condition to a first side. The second elastic member is transitioned from the compressed state to the free state and then further compressed when the torsion of the first rotor with respect to the second rotor is caused from the neutral condition to a second side. Each of the first and second elastic members is transitioned from a one-side contact state to a both-side contact state when actuated in compressed.

The second end sheet member is slidable against the first rotary member. A first intermediate sheet member included in an intermediate sheet member is disposed between the first elastic member and the second elastic member and is slidable against the first rotary member.

摘要： A damper device includes a first rotor, a second rotor, an elastic coupling part having first and second elastic members, and a hysteresis generating mechanism. The hysteresis generating mechanism includes a friction member, and generates a hysteresis torque. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where the torsion is caused between the first and second rotors by a first torsion angle from a neutral condition, makes frictional contact with the first or second rotor in a second torsion angular range exceeding the first torsion angle so as to generate the hysteresis torque, and does not make frictional contact with the first and second rotors in a predetermined torsion angular range within the second torsion angular range. In the neutral condition, the friction member is set in a neutral position by actuation of the elastic coupling part.

摘要： A damper device includes a first rotor, a second rotor, a plurality of elastic members and a stopper mechanism. The stopper mechanism includes a first stopper hole, a second stopper hole and a plurality of stop members. The first and second stopper holes are provided on both circumferential sides of each of a plurality of first window holes of the second rotor so as to circumferentially extend therefrom. One or both of the first and second stopper holes communicates at one end thereof with each first window hole and extends at the other end thereof to a position radially outside one of a plurality of second window holes of the second rotor. The stop members are fixed to the first rotor. Each stop member axially penetrates each of the first and second stopper holes and is circumferentially movable within each of the first and second stopper holes.

摘要： A torque limiter, fixed to a flywheel including an annular portion to which knock pins each including a trunk portion are fixed, is disclosed. The torque limiter includes a first plate, a second plate axially opposed to the first plate, a friction disc disposed between the first and second plates, a pressing member, and a third plate. The pressing member presses the second plate onto the friction disc. The third plate holds the pressing member together with the second plate therebetween. The third plate includes knock pin through holes such that the knock pin are fitted therein. The third plate is attached at an attachment surface thereof to the flywheel. A length between a surface of the pressing member, facing an interior of an accommodation portion of the flywheel, and the attachment surface of the third plate is shorter than a length of the trunk portion of each knock pin.
