ABSTRACT:
A door lock system includes a first link lever, a second link lever, and a spring. The first link lever moves to a transmitting position in response to an unlocking operation. The second link lever includes a ratchet driver that is formed integrally with a bushing. The ratchet driver is rotatable between a first rotational position and a second rotational position on the first link lever. In response to a door-opening operation, when the ratchet driver is in the first rotational position and the first link lever is in the transmitting position, the second link lever allows a ratchet lever to disengage a ratchet from a latch. The spring maintains the second link lever in the first rotational position when the first link lever moves to the transmitting position.
