ABSTRACT:
In an engine starter comprising a one-way clutch provided around a pinion support shaft carrying a pinion in a torque transmitting relationship but in an axially slidable manner, and an annular input gear to transmit torque to a clutch outer member of the one-way clutch, to prevent an eccentricity of the clutch outer member from seriously affecting the coupling structure between the motor and the input gear, the outer circumferential surface of the clutch outer member is provided with an external teeth serration while the input gear 12 is provided with an internal teeth serration so as to form a serration coupling. The serration coupling is provided with a sufficient radially play to accommodate a maximum eccentricity of the clutch outer member. Thus, the engine starter can be made reliable in use without requiring any undue precision during the fabrication process.
