摘要： To ensure durability of a one-way clutch, by reducing surface pressures applied to side bearings, a one-way clutch has end bearings that are disposed between an outer race and an inner race and that maintain concentricity between the races. In a supporting structure wherein one of the outer race and the inner race is fitted to a stationary member and the other race is fitted to a rotational member, a clearance of a fitting portion between the stationary member and one of the races is narrower than a clearance between the rotational member and the other race. A load resulting from whirling of the rotational member is absorbed by the greater clearance, and a high load resulting from radial movements of the race fitted to the stationary member and a weight of the race is supported by the stationary member. Thus, loads applied to the end bearings are reduced.

摘要： A hydraulic actuator has a hub, an annular recessed groove on the inner peripheral surface of the hub and an oil chamber, from which a slanted oil channel is pierced to the bottom of the recessed groove. Accordingly, there is no need for the slanted oil channel to extend to the inner peripheral surface of the hub, by which the slanted oil channel can save its length. The oil is sent from the supply oil channel formed in the boss section to the annular recessed groove of the hub in slidable contact with the boss section, and to the oil chamber through the slanted oil channel.

摘要： In a dual planetary gear of an automatic transmission, tooth surface pressure generated at a relatively short pinion is decreased and distributed since the pinion is formed as a pair of pinions. These pinions can be pinions which mesh with a sun gear or pinions which mesh with a ring gear and a single first pinion. Torque exerted on the ring gear (or the sun gear) is transmitted to the sun gear (or the ring gear) through one point of contact (or two) between the sun gear and one pinion (or a pair of pinions) and the ring gear and two points of contact (or one) between a pair of pinions (or one pinion) and the ring gear.
