A manual unlocking device for a parking lock mechanism includes an operation lever that rotates when the parking lock mechanism is switched from a locked state to an unlocked state. The operation lever is arranged outside an occupant space of a vehicle cabin and is configured that a tool can be coupled to a rotation center thereof from the occupant space. The manual unlocking device for the parking lock mechanism is configured to switch the parking lock mechanism from the locked state to the unlocked state by integral rotation of the operation lever with the tool when the tool, which is coupled to the operation lever, rotates in a state where the tool is arranged on the rotation center of the operation lever.

A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion. An output-side rotary shaft has oil passages for supplying lubricating oil to a tolerance ring. Lubricating oil is forcibly supplied through these oil passages to an annular space in which a tolerance ring is accommodated.

A manual release device for a parking lock mechanism includes an operating lever, a cable and an idle motion mechanism. The idle motion mechanism includes a body portion, a lever provided on the body portion, a helical compression spring, and a contact portion provided on the shaft. The cable is coupled to the lever. A distal end of the lever is arranged below a turning center of the lever. The parking lock mechanism is configured, when the parking lock mechanism is in a locked state, to be switched into an unlocked state as the body portion contacts the contact portion to cause the shaft to turn when the lever is turned against an urging force of the urging member as a result of operation of the operating lever to cause the body portion to turn from the normal position to the actuated position.
