Abstract: The combustion engine starter with output pinion (18) comprises a front bearing (12) provided with a front face (120) having an opening (312), a drive assembly equipped with a bush (26) passing through the opening (312) and bearing the output pinion (18) outside the front bearing (12), complementary splines (67,167). A groove (64, 164) interrupts the splines (67) of the bush (26) in order to mount a stop (60, 160) for immobilizing the pinion, a play-compensating spring (61) urging the pinion into contact with the stop (60, 160) formed by a spring ring which has a height greater than its thickness and which is housed with radial clearance at least partially in an annular recess (62) made in the front face (183) of the pinion (18); the internal periphery of the spring ring (60, 160) being mounted in the groove (64, 164) in the bush (26).
