ABSTRACT:
A starter device for an internal combustion engine which includes a starter motor, a pinion shaft rotated by the starter motor, a movable cylindrical member fitted on the pinion shaft and coupled thereto by a helical spline coupling, a pinion gear fitted for free rotation on the pinion shaft, a unidirectional clutch provided between the pinion gear and the movable cylindrical member, and the pinion gear and movable cylindrical member being coupled together for axial movement in unison with each other. In order to prevent the pinion gear from premature detachment from a ring gear of the internal combustion engine before the stable running condition of the internal combustion engine is reached, the device further includes: a pinion gear retreat-prevention member provided on the outer periphery of the movable cylindrical member, the pinion gear retreat-prevention member being axially fixed in position but radially movable relative to the movable cylindrical member; and a lock member provided at a position in the vicinity of the pinion gear retreat-prevention member so as to be engageable with the pinion gear retreat-prevention member in a state thereof when it is radially displaced by centrifugal forces.
