Abstract
In a starter motor for a starter, a plurality of permanent magnets are arranged circumferentially inside a cylindrical yoke and outside an armature. A cylindrical sleeve is fitted with the permanent magnets to radially outwardly fix the permanent magnets to the yoke. A discharge hole for discharging a cooling air from the inside to the outside of the motor is formed on the bottom of the yoke at a position between the adjacent two of the permanent magnets. The sleeve restricts the splash water from entering directly inside the motor through the discharge hole.
