Abstract
A door lock apparatus includes a latch pivotally supported on a base, a pawl pivotally supported on the base for engaging with the latch to limit its rotation, an opening lever pivotally supported on the base by the same rotary shaft as that of the pawl for being rotated to rotate the pawl, thereby disengaging the latch and the pawl, a release bush slidably pivoted on the pawl for engaging with the opening lever to transmit the rotating motion of the opening lever to the pawl, and a locking lever pivotally supported on the base for being rotated to slide the release bush, thereby disengaging the release bush and the opening lever. The locking lever is formed to have an oblong hole engaged by the release bush to transmit turning motion of the locking lever to the release bush. The oblong hole defines a circular arc whose center is the rotary shaft of the opening lever and pawl.
