Claims

[Scope of utility model registration request]

(1) In a solenoid in which a coil bobbin wound with a coil is surrounded by a yoke and a fixed iron core fixed to the inner bottom surface of the yoke is inserted into a hollow hole of the coil bobbin, a hole communicating with the other hollow hole is provided at the other end of the yoke. A solenoid in which a cylindrical plunger guide made of grooved material is force-fitted into the inner periphery of a yoke hole or hollow hole using an elastic metal plate, and the plunger reciprocates around the inner periphery of the plunger guide.

(2) Utility model registration The solenoid according to claim 1, in which the plunger solenoid is made of a magnetic material.

(3) Utility model registration The solenoid according to claim 2, in which a plurality of protrusions are formed on the inner periphery of the plunger guide, and the plunger is guided by the protrusions.

(4) Utility model registration The solenoid according to claim 1 or 2, in which a wear-resistant and highly lubricating coating such as Teflon or hard chrome plating is adhered to the inner peripheral guide surface of the plunger guide.
