ABSTRACT:
A sprocket used to transmit drive force to a coreless crawler track having rubber projections arranged at predetermined intervals on the inner peripheral surface of the crawler track. The sprocket has, on its circumferential edge, sprocket teeth arranged at the same pitch as the rubber projections. A cutout is formed at the outer circumferential tip of each sprocket tooth. Even if meshing between the rubber projections and the sprocket teeth has a trouble caused by the entry of soil and sands, the rubber projections are affected less, which greatly contributes to improvement of durability of the crawler track.
