Abstract
A starter magnet switch includes: a solenoid; an inner iron core fixed to the solenoid; a plunger attracted to the inner iron core by a magnetic field generated when the solenoid is energized; a rod starting to move when the plunger comes into contact therewith; a movable contact attached to an insulating member loose-fit to the rod; an immovable contact with which the movable contact comes into contact when the rod moves; a contact spring pressing the movable contact against the immovable contact; and a stopper receiving a biasing force of the contact spring via the insulating member, the movable contact, and an insulating washer. The stopper is fixed to the rod by subjecting a tip end of the rod to deformation and caulking. It thus becomes possible to obtain a long-life starter magnet switch by suppressing wear and deformation of parts.
