摘要： A cooling structure for a belt-type continuously variable transmission is provided to reduce the number of parts by omitting an introduction tube such as a duct. A cooling structure for a belt-type continuously variable transmission includes a belt-type continuously variable transmission(46), a crank shaft(40), a transmission case cover(36), and a side cover member(92). A transmission room(46C) is formed by surrounding the transmission case cover to a transmission case(31L) in order to cover the belt-type continuously variable transmission. A cooling fan(48F) is installed in a shaft end of the crank shaft. A cooling air introduction hole(36i) is formed in a part in which the cooling fan of the transmission case cover is faced, and introduces a cooling fan to the transmission room. The cooling air introduction hole of the transmission case cover is covered from a side direction by a side cover member. An outer air introduction hole(95) is installed in a part in which a cross section of a circumference wall of the side cover member and the transmission case cover are contacted.
