PROBLEM TO BE SOLVED: To easily fit a rotary member into a ring-like sealing member of a mechanism for transmitting a rotary force for starting an internal combustion engine without axial eccentricity. SOLUTION: The relationship between a distance Da from a start portion Pa1 on a restrained surface of a ring gear 12 to a contact start portion Pa2, and a distance Db from the start portion Pa1 on a restraining surface to the contact point Pb of a second oil sealing member 26 satisfies a formula Da<Db. Thereby, the outer periphery 12e of a cylindrical step part 12a comes into contact with the second oil sealing member 26 without causing axial eccentricity, and the ring gear 12 is moved and arranged to a regular position as it is. Accordingly, a sub-sealing rip 26b is not reversed or deformed by the axial eccentricity. This is the same with an outer race supporting plate assembled to the ring gear 12. An oil sealing property of the oil sealing member is not deteriorated thereby. COPYRIGHT: (C)2007,JPO&INPIT
