Patent ID: 7434853

Claim:
A door latch apparatus configured to close a door of a vehicle, comprising: a latch configured to engage with a striker; an actuator; a base plate; a slide groove formed on the base plate including a first groove end and a second groove end; an output lever including a first end, a second end, and a mid part, wherein the first end includes a lever shaft which is held at the first groove end or slid in a first direction from the first groove end toward the second groove end, wherein the second end of the output lever is configured to swing in a clockwise and a counterclockwise direction centering on an axis center of the lever shaft and is configured to press the latch when the output lever swings in the clockwise direction when a movement of the actuator acts on the mid part of the output lever; a cancel lever configured to be a plate member curved along the slide groove, and is disposed on the base plate, wherein the cancel lever is provided with a first elastic member between the base plate and the cancel lever, wherein the first elastic member is configured to exert an urging force so that a curved inner surface of the cancel lever comes into contact with a peripheral surface of the lever shaft and presses the peripheral surface of the lever shaft; and a supporting projection that is pressed toward the lever shaft via the first elastic force of the first elastic member and configured to regulate the lever shaft to slide from the first groove end toward the second groove end, wherein the striker and the latch are shifted from a first engagement state into a second engagement state by the movement of the actuator which causes the output lever to swing in the clockwise direction centering on the axis center of the lever shaft located at the first groove end if the shift of the striker and the latch into the second engagement state is not restricted, and wherein the movement of the actuator causes the output lever to swing, centering on an axis center of the second end, when the shift of the striker and the latch into the second engagement state is restricted so that the lever shaft is slid in the first direction beyond the supporting projection against the first elastic force.
