<P>PROBLEM TO BE SOLVED: To provide a cooling structure for a V belt type continuously variable transmission capable of increasing the amount of cooling air by increasing the air blasting efficiency, and positively supplying the cooling air to a part needing the cooling. <P>SOLUTION: This cooling structure for the V belt continuously variable transmission 3 wherein a V belt 13 is wound between a driving pulley 11 mounted on a driving shaft 9 positioned on the engine side in a transmission case 10 and a driven pulley 12 mounted on a driven shaft 14 positioned on the rear wheel side, is constituted so that an air blasting blade 25 is mounted on the outer face of a driving pulley 11 half body positioned outside the transmission case 10 of the driving pulley 11, an air blasting casing 26 surrounding the air blasting blade 25 is mounted at the transmission case side 10, and the air blasting casing 26 is provided with pressure rising passages 26a to 26c formed in a state that a clearance to the air blasting blade 25 is gradually widened toward a downstream side in the rotating direction, and discharge ports 26d to 26e are formed at downstream ends of the pressure rising passages 26a to 26c. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
