PURPOSE:To effectively prevent moisture from being intaken in an engine in accordance with hot air by forming a hot air chamber wherein an exhaust manifold is housed by an exhaust manifold cover, and extracting the hot air to be supplied to the engine from the hot air chamber. CONSTITUTION:An exhaust manifold cover 3 installed on an exhaust manifold 2 is formed to be a enclosed type, while hot air is introduced from a hot air chamber 4 provided inside the cover 3, at an air cleaner side. The exhaust manifold cover 3 is composed of a cover main body 7 which covers upper and front parts of the exhaust manifold 2, and bilateral divided pieces 8, 9 surrounding side and lower parts. A joint 11 for connecting a hot air intake is projectingly provided on an end of the cover main body 7, on the tip of which joint 11 a hot air intake port 12 is opened. A joint 19 is projectingly formed on the bottom of one divided piece 8, while a duct 20 whose end opening is an air introducing port 21 is connected to the tip of the joint 19. |
