Claim 0:
1. A vehicular parking device comprising:
a parking gear;
a parking pawl that is provided so as to be able to approach and separate from the parking gear and that mechanically suppresses rotation of the parking gear by being fitted to the parking gear;
a parking head that is arranged so as to be reciprocally movable between a parking position and a non-parking position, and that is brought into a parking state in which the parking pawl is brought close to the parking gear and the rotation of the parking gear is suppressed when the parking head is moved to the parking position;
a head moving member that is mechanically connected to the parking head and that moves the parking head from the non-parking position to the parking position when a P position for parking is selected; and, a parking lock device that positions the parking head in the parking position and holds the parking head in the parking state, the parking head being moved to the parking position when the P position is selected, wherein:
the parking lock device is configured to include a first switching mechanism that is mechanically switched between a connecting state and a non-connecting state by suppression of movement of the parking head to the parking position side after the parking head reaches the parking position in accordance with the head moving member moving in an advancing direction, the connecting state being a state in which the parking head is moved integrally with the head moving member to the parking position in the advancing direction and the non-connecting state being a state in which the head moving member is allowed to be relatively moved in the advancing direction with respect to the parking head, when a moving direction of the head moving member that moves the parking head to the parking position side is set as the advancing direction and a moving direction of the head moving member that moves the parking head to the non-parking position side is set as a retreating direction; and
the parking lock device is configured to include a second switching mechanism that is mechanically switched in accordance with relative movement of the head moving member and the parking head such that when the parking head reaches the parking position and the head moving member is relatively moved in the advancing direction with respect to the parking head, a state becomes a lock state in which the parking head is positioned in a fixing member so as to suppress the parking head from retreating to the non-parking position side, and when the head moving member is made to relatively move in the retreating direction in the lock state, positioning of the parking head with respect to the fixing member is released and the state becomes a non-lock state in which retreat of the parking head is allowed.
