Abstract:
A drive apparatus of a trunk lid lock for a motor vehicle, comprising:a striker formed on the striker base provided in a peripheral edge portion of a trunk opening; a latch provided in a trunk lid; a drive mechanism having a lock canceling member and an output member, the lock canceling member including a first cam, a second cam and a third cam; and a support base fixed to an inner panel of the peripheral edge portion of the trunk opening, the lock canceling member being supported by a shaft on the support base, the drive mechanism being operative when the latch is engaged with the striker so as to bring in a second member including the latch via a first member including the striker moving to a bring-in position from a waiting position, thereby closing the trunk lid; the lock canceling member being operative to move to a restricting position at which the latch is under a restricting state that the latch can not be taken out from the striker, and to a restriction canceling position at which the latch is under a restriction canceling state that the latch can be taken out from the striker; the output member being relatively brought into slidable contact with the first cam at a time that the first member is returned to the waiting position from the bring-in position, whereby the lock canceling member is moved from the restriction position to the restriction canceling position; during a period that the first member is returned to the waiting position from the bring-in position, the output member being relatively brought into slidable contact with the second cam, whereby the lock canceling member is restricted at the restriction canceling position; and after returning the first member to the waiting position, the output member being relatively brought into slidable contact with the third cam, whereby the lock canceling member can be moved from the restriction canceling position to the restricting position; wherein the output member comprises a cam follower bringing in the second member via the first member, the cam follower being relatively brought into slidable contact with a cam groove formed in the first member, and the cam follower being relatively brought into slidable contact with the first cam, the second cam and the third cam in this order.
