PROBLEM TO BE SOLVED: To provide an injector arrangement structure for securing the required thickness of a seat part of a valve even if a cutout is arranged on a cylinder head inner wall surface on the delivery port periphery of an injector when the fuel injection direction of the injector arranged in a direct cylinder injection engine is the direction near the side for arranging the valve. SOLUTION: An intake valve 6 and a vent valve 7 are arranged on the cylinder head inner wall surface 3a, and a delivery port 17 of the injector 14 is opened, and the cutout 18 is arranged on the cylinder head inner wall surface on the delivery port periphery of the injector. Particularly, the fuel injection direction 19 from the injector is the direction on the side for arranging the valve, and the cutout is deviatively arranged from a straight line for connecting the axis of the injector and the axis of the valve.
