Abstract: A wet friction material is mainly composed of a fiber base material, a filler, an friction adjusting agent and a thermosetting resin. The wet frictional material is prepared by impregnating with a liquid thermosetting resin a paper formed by mixing a paper-forming solid thermosetting resin with a fiber base material as at least a part of filler, and then applying heat to the paper so that it is hardened. The solid thermosetting resin is preferably a phenol resin. The liquid thermosetting resin is preferably made of a silicone resin represented by the following average composition formula and the amount of trifunctional unit monomers (RSiO3/2 in which R represents a substituted or unsubstituted monovalent hydrocarbon group) in monomers constituting said silicone resin is from 40 to 100 mol-%: (R1)a(OR2)bSiO(4−a−b)/2.

Abstract: In a torque converter equipped with a lock-up clutch device, a friction member is put on either one of a front cover and a lock-up piston which are to be brought into contact. On the front cover, coupling members are welded for coupling with an engine. Owing to welding distortion, convex portions are generated on a friction face. Thus, when the friction member is put on either side of the front cover and clutch piston, if relative rotation slippage occurs therebetween, a positive pressure and a negative pressure are produced in front of and behind each convex portion, which leads to the stick/slip. This invention gives grooves 71 each exceeding the range of a welding portion 61 of the coupling member 6 which are formed on the friction face of the friction member 7, which realizes balancing in a change in pressure.
Abstract translation: 在配备有锁止离合器装置的变矩器中，将摩擦构件放置在要接触的前盖和锁止活塞中的任一个上。 在前盖上，联接构件被焊接以与发动机联接。 由于焊接变形，在摩擦面上产生凸部。 因此，当将摩擦构件放置在前盖和离合器活塞的任一侧时，如果在其间发生相对旋转滑动，则在每个凸部的前方和后方产生正压力和负压，这导致棒/ 滑。 本发明提供了各自超过形成在摩擦构件7的摩擦面上的联接构件6的焊接部61的范围的凹槽71，这实现了压力变化的平衡。
