Claims

[Scope of utility model registration request]

A plunger supported displaceably in the longitudinal direction on the inner circumferential body of the coil frame and having a type drive section on one side in the longitudinal direction and a magnetic flux transfer section on the other side; a coil wound around the coil frame; is formed in a U-shape and has an insertion hole through which the plunger can be inserted in its connecting piece, and its side piece is magnetically coupled to a first yoke located on the outer periphery of the coil and one end of the side of the first yoke. a second yoke having an insertion hole through which the plunger can be inserted; and a return spring that biases the plunger against the plunger that is displaced to the operating position by the electromagnetic force of the coil and the first and second yokes. , a rear frame provided on a side surface of the second yoke to regulate the normal position of the plunger; and a buffer member disposed between an end of the plunger and a bottom of the rear frame; 1. A hammer solenoid characterized in that a space formed by a portion surrounded by the second yoke and the outer periphery of the coil is filled with a sound absorbing member.
