  • Electromagnetic solenoid and method for manufacturing electromagnetic solenoid
    Patent number: 11869712
    Abstract: There is provided an electromagnetic solenoid including: a stator including a stator core; a coil configured to generate an electromagnetic attractive force by energizing the stator core; a mover configured to be attracted toward the stator by the electromagnetic attractive force; and a magnetic elastic admixture including a resin material with soft magnetism and elasticity, wherein the mover is configured to be capable of reciprocating by being released by an elastic body that generates a biasing force in a direction opposite to a direction in which the electromagnetic attractive force acts, a proximal end of the mover is located at a first proximal end position upon the mover being electromagnetically attracted toward the stator during energization of the coil, and is located at a second proximal end position upon the mover being electromagnetically released and moved to a side opposite to the stator during de-energization of the coil, and the magnetic elastic admixture is configured to elastically deform b
