PURPOSE:To effectively lubricate a pair of pulleys and a belt wound therearound, by providing an oil feed nozzle in a space defined among the pulleys and the belt. CONSTITUTION:In a space defined among a main pulley 36, a counter pulley 37 and a belt 34 there is disposed and fixed an oil supply nozzle 50 having legs 53 abutting against a partition wall 7c which is formed surrounding around a hole 7b in a wall section partitioning between a pulley converting section and a gear section, so that the nozzle 50 is set in position. An oil pipe 56 is press-fitted into and connected with the oil feed nozzle 50. Further, the nozzle 50 is so arranged that the jet port of the nozzle 50 is directed along the tangential line of a substantially minimum diameter section of the counter pulley 37 on the rotationally advancing side of the belt 34 inside of the belt 34, thereby a part which offers the maximum heat generation may be effectively lubricated.
