摘要： A hydraulic clutch including a clutch drum with an outer cylinder fitted with a plurality of clutch plates and a side wall; a clutch piston that defines together with the clutch drum an engagement oil chamber, and moves in an axial direction to press the clutch plates by hydraulic pressure supplied to the engagement oil chamber; and a cancel plate that defines together with the clutch piston a cancel oil chamber that cancels centrifugal hydraulic pressure. The side wall of the clutch drum is formed with a first oil passage that radially extends and is in communication with the engagement oil chamber, and a second oil passage that radially extends and is in communication with the cancel oil chamber. One of the first and second oil passages is at least partially included in a range of an axial width of the other of the first and second oil passages.

摘要： A vehicular automatic transmission includes three single pinion planetary gear sets and a plurality of engagement elements. A plurality of gears is selectively established by three of the plurality of engagement elements being engaged and three of the plurality of engagement elements being released. One of the plurality of engagement elements is a dedicated reverse engagement element that is engaged when a reverse gear is established and is released when a forward gear is established.

摘要： An automatic transmission (11) includes a planetary gear set (PS), first to third clutches (C-1 to C-3), first to third brakes (B-1 to B-3), and a counter gear (100) that outputs shifted rotation. The counter gear (100) is placed axially on one side of the planetary gear set (PS), and the second brake (B-2) is placed axially on the opposite side from of the counter gear (100) from the planetary gear set (PS). The second brake (B-2) that does not make higher speed rotation than other clutches and brakes can thus be separated from the planetary gear set (PS), and other clutches and brakes and the counter gear (100) are arranged near the planetary gear set (PS). Thus, members having a large thickness are reduced in length, whereby the automatic transmission is made compact and reduced in weight.
