Abstract

PURPOSE:To make an effective cooling by providing a ventilating hole to an axial direction of an armature ventilating forcedly by taking advantage positive or negative pressure caused by operation of an engine. CONSTITUTION:During the operation of an engine, negative pressure is produced into an inlet pipe, and the inner space of a motor 4 connected to the inlet pipe through a suction path line 19 is also occupied by negative pressure. Therefore, when the engine starts driving, the air is inhaled from an inlet port 21 and is sucked into the motor 4. A part of the inhaled air passes through a gap in the periphery of an armature 2, the remaining part of it is shunted to the air passages 22-24 and it joins at the inside of a ventilating hole 17.
