Abstract
In a starter for a motor vehicle internal combustion engine the pinion is rotationally coupled to the drive bush by a device enabling rotation of the drive bush relative to the pinion when the rotation speed of the pinion is greater than that of the drive bush. The device has complementary front and rear friction surfaces respectively carried by the pinion and the drive bush. The pinion is mounted to be mobile axially relative to the drive bush to which it is coupled. The two friction surfaces are pressed elastically into contact with each with a predetermined force.
