PROBLEM TO BE SOLVED: To improve responsiveness of an engine by moving both an injector and a throttle valve nearer to a combustion chamber. SOLUTION: A thick portion 31 is formed by decentering a connecting cylinder fitted in a joint 15 of a throttle valve gear 16 to a side opposite to a camshaft with respect to an intake passage 21 in the throttle valve gear 16. The injector 4 is attached to the thick portion 31, and a fuel injection hole 33 connected with a fuel nozzle hole of the injector 24 is formed on the thick portion 31. The fuel injection hole 33 is formed so that one part faces an interior of the joint 15. A recessed part housing the joint 15 is formed in a side part of a cylinder head 1, and the connecting cylinder of a cylinder head 1 side for attaching the joint 15 is formed so that the joint 15 is positioned nearer to a combustion chamber 14 side than the camshaft.
