PURPOSE:To improve ventilation in a magnet switch by arranging a ventilation bush communicatable between the inside and the outside of a switch yoke in a gap between the switch yoke and a motor yoke. CONSTITUTION:Stator motor 2 is arranged in parallel with a magnet switch 1 through a gap (c). Stator housing 3 will cover the magnet switch 1 and the stator motor 2. The ventilation bush 4 will communicate between the inside and the outside of switch yoke 1b while arranged in a gap (c) between the motor yoke 2a and the switch yoke 1b to be secured between the motor yoke 2a, switch yoke 1b and the starter housing 3. Consequently, ventilation in the magnet switch can be improved.
