The present invention relates to a pulley for a caterpillar track vehicle, which is installed in the body of a caterpillar track vehicle to rotate and is used for a caterpillar track vehicle on which a track is wound up. The pulley for a caterpillar track vehicle according to an embodiment of the present invention comprises: a wheel-shaped wheel body unit; foreign-substance discharge holes inserted in between the outer circumference of the wheel body unit where the track is wound and the track to smoothly discharge foreign substances accumulated between the outer circumference of the wheel and the track. As such, the pulley for a caterpillar track vehicle can remarkably improve a running safety by maintaining tensile strength of the track for a long time and causing operating performance to be stable while the caterpillar track vehicle is running, can improve a running safety by preventing separation of the track from the pulley and can prevent damage to the pulley due to the separation of the track from the pulley. |
