Claims

[Scope of utility model registration request]

By forming an extremely thin spacer on the inner periphery of the bobbin around which the coil is wound to slidably support the piston inserted into the bobbin, a clearance is created between the spacer protrusion and the piston. A plunger with a unique feature.
