PROBLEM TO BE SOLVED: To provide a solenoid electromagnet and a solenoid adapted to eliminate a complicated process of adjusting a gap between a movable piece and an electromagnet and to increase an attractive power efficiently, and also to provide a game machine thereof.SOLUTION: A peripheral projection 445 slightly projecting from the top surface of a stationary iron core 441 is provided in a periphery of the top of the bobbin 442. A yoke 444 is provided with both upright plate units 444b, 444c in which both ends of stationary plane portions 444a are respectively erected toward the stationary iron core 441. In the ends of both of the upright plate units 444b, 444c, a groove-shaped cutout 444d is provided which permits a metal plate movable piece to move in. Because the height H1 of the bottom of the cutout 444d provided in the first and second upright plate units 444b, 444c are set lower than the height H2 of the peripheral projection 445 in the end of the bobbin 442, forming the relevant gap is achieved with a manufacturing accuracy of both upright plate portions 444b, 444c of the yoke 444, thereby dispensing with a gap adjusting operation, forming two annular magnetic circuits, and increasing an attractive force. |
