Abstract: In some embodiments, a torque damper apparatus can achieve reduced stiffness as well as sufficient vibration absorbing property while increasing the dampening ratio of the torque variation. In some embodiments, a torque damper apparatus comprises an input member to which an engine torque is inputted; damper springs able to absorb variation of torque inputted from the input member; and/or a driving power of the engine configured to be transmitted to an output shaft of a vehicle via the input member and the damper springs. The damper springs can comprise a plurality of coil springs arranged along the circumference of the input member. The torque damper apparatus can further comprise a plurality of separate members interposed between the damper springs and configured to be independently rotated with respect to each other when the engine torque is transmitted thereto.

Abstract: Provided are a wet friction plate and a wet multiplate clutch device capable of reduction drag torque while suppressing a decrease in the area of a friction member. The wet friction plate includes multiple friction members through oil grooves on a flat plate annular core metal. The friction member has first fine grooves opening at an inner peripheral edge of the friction member and extending to an outer peripheral edge side and second fine grooves opening at an outer peripheral edge of the friction member and extending to an inner peripheral edge side. The first fine groove and the second fine groove are formed to have a groove width of equal to or greater than 0.1 mm and equal to or less than 0.8 mm, and overlap portions overlapping with each other in a circumferential direction at the same position in a radial direction of the core metal.
