摘要： An internally toothed member is shown suitable for use as a clutch drum in an automatic transmission. The internally toothed member has the shape of a cup with an open end and a central axis. The cup-shaped member has first internal teeth extending in the axial direction and second internal teeth extending further toward the open end of the member than the first internal teeth. The internal teeth are each formed on an inner circumferential surface of the cup-shaped member in each of a plurality of locations spaced in the circumferential direction. Also, a groove for receiving a snap ring is formed in the second internal teeth closer to the open end than end faces of the first internal teeth facing the open end. Because the first and second internal teeth are formed projecting radially inward, they do not lower the rigidity of the internally toothed member. Also, because it is not necessary to fix a cylindrical member to the outside of the internally toothed member for reinforcement, working man-hours can be reduced and it is possible to lower the cost of the internally toothed member.
摘要翻译：显示出适合用作自动变速器中的离合器鼓的内齿构件。内齿构件具有开口端和中心轴的杯形。杯状构件具有沿轴向延伸的第一内齿，并且第二内齿比第一内齿更向前延伸到构件的开口端。内齿分别形成在圆周方向间隔开的多个位置的杯状部件的内周面上。此外，在第二内齿形成比接近开口端的第一内齿的端面更靠近开口端的用于容纳卡环的槽。由于第一内齿和第二内齿形成为径向向内突出，所以它们不会降低内齿构件的刚性。此外，由于不需要将圆筒形构件固定到用于加强的内齿构件的外侧，所以可以减少工作时间，并且可以降低内齿构件的成本。

摘要： An automatic transmission has a rotational shaft with an axial through-hole. The shaft is supported by a case through bearings at opposite ends thereof. In the hole, a cup-type plug with holes is engaged with the shaft at one end thereof. A lubricating means is disposed in the case facing the holes for distributing a lubricating hydraulic fluid to bearings disposed at each end of the shaft.

摘要： An automatic transmission includes: a connection member including an outer cylinder and an inner cylinder and defining a first annular space; a first annular piston arranged in the first annular space and defining a second annular space together with the inner cylinder; a second annular piston arranged in the second annular space; a spring retainer mounted on the inner cylinder in opposition to the second annular piston; a spring interposed, between the spring retainer and the second annular piston; a first clutch adapted to come into and out of engagement with a sun gear by the actuation of the first annular piston 72; a second clutch adapted to come into and out of engagement with an input shaft by the actuation of the second annular piston and left disengaged during forward running; a one-way clutch arranged adjacent to the first clutch and adapted to come into and out of engagement with the sun gear; and a brake interposed between the outer cylinder and the transmission casing. The one-way clutch has its outer race fixed to a flange, which is splined to the outer cylinder, and its inner race fixed to the flange of the first clutch and splined to the sun gear.
