<p>In an internal combustion engine, shafts of respective first and second valve members are inclined with respect to the center axis of a cylinder bore. Each of first and second swing arms is arranged such that a cam contact member thereof is located closer to the center axis of the cylinder bore than first and second ends thereof are. The first and second swing arms are arranged such that the cam contact members are overlapped with each other when viewed from the axial direction of the camshaft. The crankshaft, camshaft, and cam contact members are arranged to be offset from the center axis of the cylinder bore in a thrust direction of the piston.</p> |
