摘要： A vehicle drive-force transmitting apparatus including: a mode switching clutch; a torque converter; a lock-up clutch included in the torque converter; a switching solenoid valve configured to output a switching pressure for switching an operating mode of the mode switching clutch between a one-way mode and a lock mode; and a lock-up clutch control valve configured to switch an operating state of the lock-up clutch between an engaged state and a released state. The mode switching clutch is to be placed in the lock mode when the switching pressure is supplied from the switching solenoid valve to the mode switching clutch. The lock-up clutch control valve is configured to receive the switching pressure supplied from the switching solenoid valve, and to switch the operating state of the lock-up clutch to the released state when the switching pressure is supplied to the lock-up clutch control valve.

摘要： In an automatic transmission including a deceleration planetary gear and a hydraulic clutch, the hydraulic clutch includes a clutch drum, a clutch hub, first and second friction engagement plates, a piston, and an engagement oil chamber defining member. The clutch hub is formed by a ring gear and a support member that rotates together with the ring gear. The piston is movably supported by the clutch hub. The piston and the support member define a cancel oil chamber that cancels a centrifugal oil pressure generated in an engagement oil chamber.

摘要： A power transmission device for a vehicle includes a first power transmission path that is provided between an engine and a driving wheel, a second power transmission path that is provided in parallel with the first power transmission path, and an electronic control unit. The electronic control unit changes over a secondary clutch to a one-way mode while releasing a first clutch, when a request is made to change over a power transmission path between the engine and the driving wheel from the first power transmission path to the second power transmission path at a time of a predetermined state. The electronic control unit is configured to engage a second clutch when the secondary clutch is changed over to the one-way mode.
