Abstract
A linear solenoid includes a coil assembly having a coil, and a cup-shaped yoke arranged at an outer peripheral side of the coil. The yoke is provided with a recess portion that is opened at least at a position in a circumferential direction of the yoke and extends in an axial direction of the yoke. The coil assembly includes a connector portion that has a terminal connected to an exterior and is exposed from the recess portion to an exterior of the yoke, and a secondary molding portion made of a secondary molding resin in which the coil is insert-molded. Furthermore, the secondary molding portion includes a cover portion that is arranged to cover the recess portion of the yoke from an outer peripheral side of the recess portion. Thus, the cover portion can restrict foreign-material mixed oil from being introduced into the yoke.
