本考案は、ソレノイドにおける磁気吸収力を利
用してラツチ棒を駆動するソレノイド式ロツク装
置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a solenoid-type locking device that drives a latch rod by utilizing the magnetic absorption force of a solenoid.

On the other hand, while locking the door panel,
When the solenoid is energized, the solenoid coil is energized and the plunger is attracted, thereby disengaging the tip of the plunger from the receiving hole on the fixed frame side and unlocking the door panel.

寿命を短くしている。(Problem to be solved by the invention) However, in such a solenoid type locking device, a large current is applied to the solenoid coil in order to overcome the frictional resistance between the plunger and the guide member and the receiving hole during suction operation. However, since this large current continues even while the lock is unlocked, the solenoid coil tends to overheat.
Solenoid seizure shortens the life of solenoid locks.
