Abstract

A starter device for internal combustion engines comprises a drive shaft (11), a control assembly (13) for a pinion gear (17) rotatingly and axially movable on the driver shaft (11), and a centrifugally actuated locking unit (16) fastened to the drive shaft (11) to retaing the control assembly (13) from backward sliding during starting of the engine. The control assembly (13) comprises the pinion gear (17), and a thrust element (19) coupled to the drive shaft (11) by helical splines (21), and an intermediate unidirectional roller clutch (20). The centrifugally actuated locking unit (16) comprises face to face arranged locking members (26, 27) radially sliding into an open cage (25) fastened to rotate with the drive shaft (11). Each locking member (26, 27) is provided with an arch-shaped weight portion (30) and a tooth member (32) to stop the thrust element (19), connected by at least one intermediate arm (31). Guide means (33, 34; 42) are provided on the locking members (26, 27) and the guide cage (25) to radially guide the same locking members (26, 27) during movement under centrifugal forces.
