<p>In a V-type engine (E), intake and exhaust rocker arms (71a, 72a, 71b, 72b) in each bank (B1, B2) are arranged in a substantially inverted-V-shape in a plan view, so that side end portions of corresponding intake and exhaust push rods (44a, 44b, 45a, 45b) are positioned adjacent to each other. Slipper portions (48) of first and second intake cam followers (42a, 42b) have end portions at one end along the axial direction of a camshaft (38), protrude respectively in the opposite directions to each other so that they face each other across an intake cam (38i) therebetween. Slipper portions (48) of first and second exhaust cam followers (43a, 43b) have end portions at one end along the axial direction of the camshaft (38), protrude respectively in the opposite directions to each other so that they face each other across an exhaust cam (38e) therebetween. This reduces the distance between the push rods (44a, 44b, 45a, 45b) in each bank to provide a compact valve-operating device.</p> |
