PURPOSE:To attach a steel belt to a pulley without using any attachment screw by fixing the middle part of the steel belt to a metallic member by means of a melt-sticking means and at the same time fixing the metallic member to the pulley. CONSTITUTION:A steel belt 22 contains a welding part 22A of large width formed at the middle part and in the lengthwise direction of the belt. While a metallic member 23 which is melt-stuck to the belt 22 in a body contains a flat plate part 23A which is fitted to a groove 21A of a pulley 21 and a pin part 23B which is protruded at the back side of the part 23A and then fitted with pressure into a pin pressing hole 21B. A welding surface having the same curvature as the pulley 21 is formed on the upper surface side of the part 23A. Then the part 22A of the belt 22 is melt-stuck to the part 23A of the member 23 at welding positions 24 respectively. |
