Abstract
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 (10b) and extend circumferentially.
