In a starter with which a pinion movable body with which a pinion gear and a one-way clutch were united moves on an output shaft, a holder is attached to the one-way clutch. A seal component having the shape of a ring is provided so that an end of an outer circumference of the seal component is fixed to a nose part of a housing and an end of an inner circumference of the seal component slidably contacts an outer circumferential surface of the holder. The holder is provided so that relative rotation to the one-way clutch is possible. Since the holder doesn't rotate relative to the housing, wear of a seal component is reduced compared with the case where the seal component contacts the one-way clutch which rapidly rotates whereby the sealability preventing a foreign substance or water from infiltrating into the inside of the starter can be maintained.
A starter having a motor which generates torque by being energized, an output shaft which rotates in response to the torque of the motor, a pinion movable body which has a pinion gear provided on the output shaft so that axial movement is possible, a housing which accommodates the pinion movable body inside and a seal component which seals a gap between the pinion movable body and the housing, and the starter whose pinion gear is pushed towards a ring gear then engages with the ring gear whereby the engine is cranked, wherein;
