Abstract
The present invention provides a lock device for locking by inserting a striker into a base member. The lock device includes a latch, which is disposed on the base member and constrains and releases the striker, and a pawl, which holds the latch. Backlash of the latch is limited by a simple structure. A cam member is rotationally connected to the base member by a rotation shaft different from that of the pawl. An engaging protrusion and recess are formed on the pawl and cam member, respectively. When the pawl is at an allowable position, the protrusion and recess are engaged with each other to hold the cam member. The engagement is released when the pawl rotates to a holding position, engaging the cam member with the latch, which is at a locked position, thereby rotating the latch such that the striker contacts the bottom surface of a base groove.
