To provide a transmission device for transmitting the torque of a crank shaft 11 to a supercharger 130a, suppressing the worsening of fuel consumption without using a component such as an electromagnetic clutch involving increases in weight, cost and power consumption, while sufficiently exerting the capability of the supercharger 130a without any impairment.
A flat belt 70 is wrapped around between a crank pulley 30 of the crank shaft 11 and an output pulley part 40 consisting of a high speed ratio flat pulley 50 and a low speed ratio flat pulley 60 connected to a rotating shaft 131a of the supercharger 130a. The flat belt is displaced between the side of the high speed ratio flat pulley 50 and the side of the low speed ratio flat pulley 60 by a speed ratio change-over part 80, whereby the rotating shaft 131a is changed over between a high speed ratio for accelerating travel and a low speed ratio for constant speed travel for rotational drive.
