Device for angularly positioning a starter cylindrical head with respect to the support thereof

摘要

The inventive device for angularly positioning a starter on a support ( 11 ) interfacing with a thermal combustion engine for a motor vehicle comprises indexing means, at least one projection ( 12 ) which is axially connected to the cylindrical head ( 10 ) and introducible into a complementary slot ( 13 ) arranged in the support ( 11 ) in order to form an indexing area ( 14 ) for fixing and angularly orienting a rotational inductor coil with respect to the support ( 11 ) without increasing radial thickness thereof. In such a manner, the angular indexing function is transferred to the interfacing support ( 11 ). The projection ( 12 ) is separated from the slot ( 13 ) by a clearance in order to form an outlet orifice ( 21 ) enabling water to be evacuated from the starter.
