Abstract
A drive apparatus includes a sun gear, a ring gear, a carrier which supports planetary gears, a drive source which drives the ring gear as an input element, and fixing mechanism which fixes selectively one output element of the sun gear as a first output element and the carrier as a second output element so as not to rotate, and driving force is outputted from the other output element which is other than the one output element of the sun gear and the carrier fixed by the fixing mechanism.
Claims6
A drive apparatus comprising:
- a sun gear;
- a ring gear disposed coaxially with the sun gear and on an outer side of the sun gear;
- a planetary gear disposed between the sun gear and the ring gear so as to mesh with the sun gear and the ring gear;
- a carrier disposed coaxially with the sun gear and the ring gear, the carrier being configured to support the planetary gear;
- a drive source configured to drive an input element, the input element being one rotary element selected from a group of the sun gear, the ring gear and the carrier;
- and
- a fixing mechanism configured to fix selectively one of output elements of a first output element and a second output element so as not to rotate, the first output element and the second output element being two rotary elements other than the input element of the sun gear, the ring gear and the carrier,
- wherein the drive apparatus is configured to output driving force from the other output element that is other than the one of output elements of the first output element and the second output element fixed by the fixing mechanism,
- wherein the input element is the ring gear,
- wherein the first output element is the sun gear, and
- wherein the second output element is the carrier.

- wherein the drive apparatus is configured to output driving force from the other output element that is other than the one of output elements of the first output element and the second output element fixed by the fixing mechanism;
- and
- a lock apparatus configured to hold a vehicle door in a fully closed state and a half closed state and to perform a releasing operation, in which the vehicle door staying in the fully closed state or the half closed state is shifted to an openable state, and a closing operation, in which the vehicle door staying in the half closed state is shifted to the fully closed state,
- wherein the lock apparatus comprises:
- a latch that is moveable to each of a full latching position where the latch holds the vehicle door in the fully closed state, a half latching position where the latch holds the vehicle door in the half closed state, and an unlatching position where the latch holds the vehicle door in the openable state;
- and
- a ratchet that is moveable to each of a locking position where the ratchet locks the latch which stays in the full latching position or the half latching position so as to prevent the latch from moving towards the unlatching position and an unlocking position,
- wherein in the releasing operation, the ratchet is moved from the locking position towards the unlocking position by means of the driving force which is outputted from the first output element of the drive apparatus,
- wherein in the closing operation, the latch is moved from the half latching position towards the full latching position by means of the driving force which is outputted from the second output element of the drive apparatus,
- wherein the input element is the ring gear,
- wherein the first output element is the sun gear, and
- wherein the second output element is the carrier.
