Claims

[Scope of utility model registration request]

(1) An axial fitting hole is formed in either of the opposing ends of the fixed core and the movable core, and a protrusion that protrudes from the end face of one core toward the other side is provided in the fitting hole. A solenoid having a shock absorbing member fitted therein.

(2) The solenoid according to claim 1, wherein a circumferential groove having a volume corresponding to at least the volume of the protrusion of the buffer member is formed around the opening of the fitting hole.

(3) Utility model registration claim 1 in which a plurality of protrusions are formed on the outer circumferential surface of the buffer member, protruding radially outward and having a full length or less from the fitting side to the protrusion side.
Solenoid as described in section.
