Zusammenfassung:	The utility model provides a power unit of a saddle type vehicle, which can reduce the temperature of a transmission chamber with a simple structure. A power unit for a saddle-type vehicle is provided with a housing (23, 40, 41), a crankshaft (32) housed in the housing (23, 40, 41), and a belt-type continuously variable transmission (43) that changes the speed of driving force transmitted from the crankshaft (32) and transmits the driving force to a drive wheel (15). The housing (23, 40, 41) is provided with a crankshaft chamber (35) for accommodating the crankshaft (32) and a transmission chamber (42) for accommodating the belt-type continuously variable transmission (43), an air layer space (100) for forming an air layer is provided between the crankshaft chamber (35) and the transmission chamber (42), and the power unit of the saddle-type vehicle is provided with an air guide mechanism (110) for guiding air to the air layer space (100). 本实用新型提供一种鞍乘型车辆的动力单元，能够以简单的结构降低变速器室的温度。鞍乘型车辆的动力单元具备壳体(23、40、41)、收容于所述壳体
