摘要

Motor vehicle starter comprising a starter head provided with a pinion ( 1 ), a driver ( 2 ) and a coupling device with a conical clutch for coupling the pinion to the driver ( 2 ), in which the conical clutch comprises a first frustoconical friction surface ( 8 ) fixed to the pinion and a second frustoconical friction surface ( 8 ') with a shape complementary to the first surface ( 8 ) and fixed to the driver and in which the coupling device comprises on the one hand a hollow-shaped coupling piece having. a bottom extended by an annular skirt directed axially towards one of the elements consisting of pinion and driver and on the other hand axially acting elastic means ( 10 ) bearing on a first stop fixed to the coupling piece for acting on a second stop fixed to one of the elements consisting of pinion and driver. The elastic means comprise axially deformable tongues ( 10 b) and extend circumferentially.
