Abstract: A valve gear operates an intake valve for a plurality of cylinders. The valve gear includes a driving cam shaft that rotates with an engine crankshaft, a driven member operated by a driving cam of the driving cam shaft, a pivot member which pivots in association with movement of the driven member causing the intake valve to reciprocate, and a valve gear case accommodating the cam shaft, the driven member, the pivot member, and a control shaft. The valve gear case mounts to an intake-side part of a cylinder head, and includes end wall portions at both ends in a longitudinal direction, an inter-cylinder wall portion, and connection wall portions connecting the end wall portions and the inter-cylinder wall portion.

Abstract: Support bases for supporting camshafts in a rotatable manner are mounted on the cylinder head of an internal combustion engine. The support bases are provided so as to be separated from each other in the axial direction of the camshafts. Each of the support bases comprises bearing portions which support the camshafts and a through-hole which extends in the axial direction of the camshafts. A rod is inserted through the through-holes, and the rod restricts the bearing portions from being displaced from positions at which the bearing portions are located while the internal combustion engine is stopped and cold.
