In a V-type engine, intake and exhaust rocker arms in each bank are arranged in a substantially inverted-V-shape in a plan view, so that side end portions of corresponding intake and exhaust push rods are positioned adjacent to each other. Slipper portions of first and second intake cam followers have end portions at one end along the axial direction of a camshaft protrude respectively in opposite directions to each other so that they face each other across an intake cam therebetween. Slipper portions of first and second exhaust cam followers have end portions at one end along the axial direction of the camshaft protrude respectively in opposite directions to each other so that they face each other across an exhaust cam therebetween. This reduces the distance between the push rods in each bank to provide a compact valve-operating device.
