<p>The starter drive consists of a plurality of wedging sprags (1) placed in rectangular unilaterally opened holes in outer (2) and inner (3) cages. Between the two rigid cages is disposed a smooth band cage (4). The cages (2, 3 and 4) together with the sprags (1) are disposed between the inner contact surface (5) with circular cross-section of the shaft (6) of the driving gear (7) and the outer contact surface (8) with circular cross-section, which is worked out in a casing (9) of the starter drive. The starter drive is used in machine-building and more specially in transport machine-building for starting internal combustion engines. The starter drive has a simplified construction, increased reliability and loading capacity. <IMAGE></p>
