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.
