摘要： Provided is an automatic transmission for a vehicle having a compact device configuration.
At least one of a clutch (C) and a brake (B), which are a plurality of engaging elements, is a second clutch (C2) which is a meshing-type engaging element. As a result of at least a portion of the second clutch (C2) being provided on the inner peripheral side of a second one-way clutch (F2) and a third clutch (C3), which are other engaging elements, it is possible to minimize other configuration design changes when arranging the meshing-type engaging element, and to reduce the total length of the automatic transmission (10) as much as possible.

摘要： A vehicle power transmission device includes: an input shaft (20); an output shaft (30); a first power transmission path (PT1) configured to transmit power between the input shaft (20) and the output shaft (30); and a second power transmission path (PT2) configured to transmit power between the input shaft (20) and the output shaft (30). The first power transmission path (PT1) includes a mode-switching clutch (S1) configured to be switched between a one-way mode and a free mode, the one-way mode being a mode in which power acting in a forward rotation direction is transmitted while power acting in a reverse rotation direction is interrupted, and the free mode being a mode in which power acting in the forward rotation direction and power acting in the reverse rotation direction are interrupted. The second power transmission path (PT2) includes a control clutch (C2) configured such that a torque capacity of the control clutch (C2) is controllable.
