  "textContent": "An internal combustion engine optimizing small-size arrangement of the valve drive mechanism, considering that the exhaust valve diameter is smaller than the intake valve diameter. Intake and exhaust valves (41, 42) are in a radial arrangement, intake and exhaust cam surfaces (54b, 55b) are inclined relative to intake and exhaust cam axes (L5, L6), intake and exhaust rocker arm support members (72, 73) are inclined correspondingly in the same way and disposed between an intake camshaft (52) and an exhaust camshaft (53). Pivotal support base portions (70a) of intake rocker arms (70) and pivotal support base portions (71a) of exhaust rocker arms (71) are disposed such that the distances thereof from a joining surface (P1) joining a cylinder head (13) and a cylinder body (12) are different.",
