PURPOSE:To reduce wear by making a weight of a V-belt of an outside weight adjusting member of metal material and inside resin in which solid lubricant is mixed. CONSTITUTION:A V-belt system automatic transmission 10 is constituted from a crank side pulley 12 supported by a crankshaft 4, a rear wheel side pulley 14 supported by a rear wheel side pulley shaft 5 through a rotatable collar 13. a V-belt 15, etc. A weight 16 having a circular section engages the back face of a movable pulley plate 12b and a cam surface inside a peripheral wall. A cam member 17 is formed in the bevel manner and sandwiches radially slidably the weight 16 between itself and the movable pulley plate 12b. The weight 16 is provided at the inside with a weight adjusting member 18 made of metal material like iron and at the outside with resin in which solid lubricant is mixed or resin system composite material which is filled with fibers. |
