ABSTRACT:
A starter that can improve heat radiation efficiency and improve the brush life. An upper movable contact is set on the end of a plunger shaft fixed on a plunger. The upper movable contact moves together with the plunger due to the attraction force of an attraction coil and contacts a fixed contact set to face the upper movable contact and which is connected to a terminal bolt. The upper movable contact is directly installed and integrated with a brush, so the heat generated by the bush is efficiently dissipated through the brush, upper movable contact, fixed contact and terminal bolt out the battery cable connected to the terminal bolt.
