A pair of intake valves are arranged on the other side of the inner wall of the cylinder head. Inflow suppressing walls for suppressing the inflow of the intake air from the openings of the intake valves are formed along the peripheral portions of the intake valves positioned opposite to the exhaust valves and positioned between the intake valves. The parts of the inner wall of the cylinder head around the peripheral portions of the intake valves positioned opposite to the exhaust valves and positioned opposite to the other intake valves are expanded outward from the cylinder bore.
