Claims

[Scope of utility model registration request]

A yoke that houses the coil inside, a movable core that penetrates the yoke and is inserted into the coil so that it can move forward and backward, and a fixed core that is fixed to the yoke opposite the end of the movable core that penetrates the coil. and a return spring that biases the movable iron core in the direction of pulling it out from the coil.By energizing the coil, the movable iron core is attracted to the fixed iron core against the spring force of the return spring, and this movable iron core is pulled out from the fixed iron core. In a solenoid equipped with a locking mechanism that maintains the adsorption state, a recess formed on the circumferential surface of the movable core and a spring biased so that the movable core slides into contact with the circumferential surface of the movable core when the movable core is attracted to the fixed core. At the same time, the lock pin fits into the recess of the movable core when the movable core contacts the fixed core, and the lock pin is moved in the direction to remove it from the recess of the movable core when releasing the adsorption state of the movable core to the fixed core. The solenoid constitutes the above-mentioned locking mechanism with a driving means for causing the solenoid to move.
