PURPOSE:To eliminate the damage of metal belt members due to pinching pressure and realize smooth mutual tilting of V-shape metal members by a structure wherein elastic metal members consisting of hollow rollers are engaged to the opposing faces of the V-shape metal members while the V-shape metal members are bonded through the elastic metal members with the metal belt members. CONSTITUTION:Elastic metal members 9 are composed of hollow rollers and engaged in arcuated recesses 10 and 10 formed on the opposing surfaces of V- shape metal members 8 and 8 and at the same time tightly fastened along the outer peripheries by metal belt members 7 so as to urge the elastic metal members 9 and V-shape metal members 8 therethrough in order to realize mutual bondings among the members 7, 9 and 8. When the V-shape metal members 8 engage with the V-grooves 3 of a V-pulley 2 at drive side and follow with the V-pulley 2, the belt members 7 are driven at the tension side. Furthermore, during actuation, the V-shape metal members 8 tilt themselves each other in an arcuate motion and said tilting can be smoothly realized due to the respective rollers lain between the V-shape metal members 8. |
