A running machine is provided to secure the permanent life time by changing the position of rubber footing bars after loosening a bolt and to obtain the same effect as a belt by settling the rubber roller footing bars in parallel. The running machine is composed of an annular rod-shaped pipe having foot sole finger-pressure projections formed by molding the outer diameter of a general hose or a hose model with annular pipe materials in a mold injection-molding machine and a rubber roller footing bar(1) into which the annular rod-shaped pipe is inserted. The rubber roller footing bar is formed by coating the annular rod-shaped pipe with liquid rubber material. A running machine body is completed by settling support bars(4) on recessed grooves and then fastening bolts(5).
