Abstract
In a starter system for an internal combustion engine, an input member of an overrunning clutch is provided with an annular shoulder surface abutting an annular end surface of a cylindrical boss portion of a reduction gear unit casing when the overrunning clutch is at a rest position, and a cylindrical sleeve portion extends from the annular shoulder surface towards the reduction gear unit so as to be closely fitted on the cylindrical boss portion of the reduction gear unit casing. Thus, water and other foreign matters are not only shut off by these mutually abutting annular surfaces, but also prevented from reaching this region by the cylindrical sleeve portion closely fitted on the cylindrical boss portion of the reduction gear unit. Also, the centrifugal force prevents water and other foreign matters from reaching this area when the starter is actuated and the two annular surfaces are not in contact.
