Claim 1:
2. The vehicular parking device according to claim 1, wherein:
the parking lock device is configured to include a first member that is moved integrally with the head moving member and a second member that is moved integrally with the parking head;
the second member includes a first fitting portion provided with a first fitting hole to which the first member is fitted so as to be movable in an axial direction, and a second fitting portion fitted in a second fitting hole provided in the fixing member such that the second fitting portion is movable in the axial direction, the first fitting portion and the second fitting portion being provided on the same axis;
the first switching mechanism includes a first locking member disposed so as to be able to project outward from an outer peripheral surface of the first member, a first engaging recess portion that is provided on an inner peripheral surface of the first fitting hole of the second member and that is engaged with the first locking member, and an elastic member that urges the first locking member so as to project outward, the first locking member is engaged with the first engaging recess portion in accordance with an urging force of the elastic member, causing the first member and the second member to be brought into the connecting state, and the first locking member is pushed inward of the first member against the urging force of the elastic member, causing the first member to be brought into the non-connecting state in which the first member is allowed to be relatively moved in the advancing direction with respect to the second member; and
the second switching mechanism includes a second locking member disposed so as to be able to project outward from an outer peripheral surface of the second fitting portion of the second member, a second engaging recess portion that is provided on an inner peripheral surface of the second fitting hole of the fixing member and that is engaged with the second locking member, and a pushing out engaging portion that is provided in the first member and that pushes the second locking member outward and makes the second locking member engage with the second engaging recess portion when the parking head reaches the parking position and the first member is moved relative to the second member in the advancing direction, the second locking member being brought into the lock state in which the second member is suppressed from retreating to the non-parking position side by the second locking member being pushed outside from the second member by the pushing out engaging portion and engaged with the second member, and the non-lock state due to release of engagement of the second locking member and the second engaging recess portion by the pushing out engaging portion is released when the first member is caused to relatively retreat to the non-parking position side with respect to the second member in the lock state.
