ABSTRACT:
A crawler block rubber pad for a crawler which has an endless path of movement and which is used for a vehicle. Links are axially supported and connected by pins in an endless shape, and crawler blocks are attached to outer surfaces of the links. In the crawler block rubber pad, a rubber pad is formed integrally, by vulcanization and adhesion, to an outer side surface of a crawler block and to end portions of the crawler block as seen from a longitudinal direction of the links. Preferably, the rubber pad is vulcanized and adhered to both end portions of the crawler block in the longitudinal direction of the links. Even if a small stone or the like becomes caught in a space between crawler blocks which space widens when the crawler is trained around an idler or the like, because a thickness of rubber material is provided so as to be larger than a radius of a small stone, no unwanted force is applied to the pins and the links.
