Abstract
In a starter, a motor rotation shaft and an output shaft are connected through a reduction device. The output shaft is held rotatably by a rear bearing. The bearing has a plurality of through holes between the inner surface and the outer surface. A housing of the starter has a holding part for holding the bearing. A groove is formed annularly in the inner peripheral surface of the holding part. The groove is communicated with the through holes of the bearing. A seal member is press-fit in the holding part in proximity to a pinion gear side of the bearing. The seal member prevents foreign substances from entering the bearing surface of the bearing and inhibits the flowing out of lubricant from the bearing.
