Separation of, or damage to, the inlet duct and outlet duct connected to a belt-type variable transmission is reduced, and durability of the belt-type variable transmission is improved, by preventing induction of foreign matter such as water, mud, sand or dust into the inlet duct. An induction box is provided between a front cover and a front upper part of a vehicle frame that extends above the front wheel axle shaft, and this induction box is fixed to a side of the vehicle frame. A cooling air induction port is provided in an upper face of the induction box adjacent to the bottom face of the front cover. A duct linkage port in the bottom face of the induction box and an air induction port of the belt-type variable transmission are connected by an inlet duct. A positioning element in the form of a fitting hook is formed unitarily and in one piece with the inlet duct on a middle portion of the inlet duct so that the positioning element positions the middle portion of the inlet duct with respect to structural members of the vehicle frame.
