Abstract
A solenoid includes a stator at a position facing an opening of a housing member. The stator includes a conical protrusion portion and a side surface made from a magnetic body. The side surface extends from an outer periphery of a reduced diameter portion in a direction away from the opening of the housing member. The solenoid includes a yoke with a fixation hole having an inner peripheral surface to which a part of a side surface portion of the stator is fixed. A non-contact portion, where the yoke and the side surface portion are out of contact with each other, is defined on a housing member side of the fixation hole. The solenoid includes a non-magnetic connection member joined by being heated between the housing member and the yoke, and a movable element which is axially movable in the housing member and made from a magnetic body.
