In a V-type engine in which first and second banks arranged in a V-shape are provided continuously to a crankcase, and in which a carburetor is placed at a valley between the first and second banks, the carburetor is placed spaced from the first and second banks. Further, the carburetor is connected to intake ports of the first and second banks via first and second intake pipes, respectively, and first and second heat shield plates each made of synthetic resin are attached to side faces of the respective first and second banks, the side faces facing the carburetor, each of the first and second heat shield plates covering a corresponding one of the side faces and defining a cooling air passage between the heat shield plate and the side face. Accordingly, it is possible to surely prevent heat from the banks from affecting the carburetor in order to prevent percolation in the carburetor even in the case where the engine stops its operation in a high-temperature state.
