Lock system for motor vehicle

摘要

A lock plate moves in a direction indicated by an arrow by the operation of a detent knob. A stopper plate to which a main body of an electromagnetic solenoid is fixed is designed to reciprocate between a lock position and an unlock position, the lock position being a position at which a stopper section confronts the lock plate and the unlock position being a position at which the stopper section evacuates from the lock plate. The stopper plate is normally urged toward the lock position by return springs. A cam member coupled to a plunger of the electromagnetic solenoid receives a force to move to the unlock position through the operation of the cam with respect to the lock plate. A resiliency of the return springs is set to a value smaller than a resultant force of a plunger attracting force of the electromagnetic solenoid and a resiliency of a trip spring that urges the plunger in a plunger attracting direction.
