PROBLEM TO BE SOLVED: To provide an electromagnetic switching device capable of preventing a shaft from inclining with respect to the moving direction of a movable iron core. SOLUTION: An electromagnet device 1 has a fixed member provided with an exciting coil 3 and a fixed iron core 6 allowing the penetration of magnetic flux generated in the exciting coil 3, and a movable iron core 7 attracted to the fixed iron core 6 according to the on/off of current application to the exciting coil 3 to move straight in one direction. A shaft 19 penetrates the fixed iron core 6 in one direction and connects the movable iron core 7 to one end thereof. A contact device 2 has a contact mounted to the other end of the shaft 19 to open/close following the movement of the movable iron core 7. The fixed member has a guide cylinder 12 enclosing the movable iron core 7, and a cap 16 arranged between the fixed iron core 6 and the contact device 2 and provided with a bearing hole 36 inserting the shaft 19 through. The inclination of the shaft 19 with respect to the one direction is regulated by the guide cylinder 12 and the cap 16. COPYRIGHT: (C)2008,JPO&INPIT
