According to the present invention, an endless belt-shaped elastic member, which is wrapped around a drive wheel and idler wheels, has supporting parts and separating grooves. The supporting parts are formed protruding from an inner circumferential surface of the elastic member and support the drive wheel and idler wheels by being in contact with outer circumferential surfaces of said wheels.
