Abstract

A linear solenoid has a coil assembly, a plunger, a stator core, and an elastic member. The coil assembly has a coil provided by a conducting wire. The plunger is disposed inside of the coil assembly and is movable in an axial direction. The stator core has a guiding portion guiding the plunger to move in the axial direction, an attracting portion attracting the plunger by generating a magnetic attractive force when the coil is energized, and a blocking portion blocking a magnetic field between the guiding portion and the attracting portion. The elastic member has an annular shape and is disposed between the blocking portion and the coil assembly. The elastic member is in contact with both an outer wall surface of the blocking portion and an inner wall surface of the coil assembly entirely in a circumferential direction of the elastic member.
