摘要： A friction plate is constituted by a core plate, and friction members fixed respectively to opposite surfaces of the core plate. The friction member has oil passages, extending therethrough from its inner peripheral surface to its outer peripheral surface, and oil grooves which are open to the inner peripheral surface, but do not extend through the friction member. The area ratio of the oil grooves to the oil passages is 25% to 100%; and the width of the oil groove is not larger than the width of the oil passage. The length of the oil groove is not less than 1/4 of the length of the oil passage. It is not necessary that all of the oil grooves have the same length. Preferably, the width of the oil passage, as well as the width of the oil groove, is not more than 3 mm. The oil passages and the oil grooves may be inclined relative to the radial direction.

摘要： In a torque converter with a lock-up mechanism which can decrease a distribution of hydraulic pressure in the radial and circumferential directions of a frictional material, which can prevent the creation of any excess reaction by the distribution of hydraulic pressure, and which can efficiently give a fastening force to the frictional material to thereby improve transmission torque capacity, an oil groove for reducing the distribution of hydraulic pressure is provided on the frictional material or a piston. This oil groove is provided for depressurization at a location which does not hinder the fastening function.

摘要： A wet-type multiplate clutch has an outer circumferential drum section, an inner circumferential hub, a pressing member, and a clutch engagement unit composed of plural friction plates and separator plates alternately arranged between the drum section and the hub. One of mutually-contacting walls of the drum section and clutch engagement unit and one of mutually-contacting walls of the unit and pressing member are provided at their predetermined contact areas with inclinations such that, when the clutch is out of engagement, the mutually-contacting walls of the drum section and unit and the mutually-contacting walls of the unit and pressing member form wedge-shaped spaces between them, respectively, as viewed in a radially-extending, axial cross-section, said wedge-shaped spaces being gradually reduced in widths thereof toward an exterior in a radial direction and, when the clutch is in engagement, the mutually-contacting walls of the drum section and unit and the mutually-contacting walls of the unit and pressing member radially extend at right angles relative to a central axis of the wet-type multiplate clutch and are in close contact with each other, respectively.
