Claims

[Scope of utility model registration request]

A buffer body made of an elastic material that protrudes from the recess and prevents collision between the fixed iron core and the movable iron core is disposed in a recess provided in at least one of opposing surfaces of the fixed iron core and the movable iron core, The plunger solenoid is characterized in that the buffer body is deformed into the recessed portion by a suction force that attracts the movable core so that the fixed core and the movable core come into contact with each other.
