    摘要： A scooter type vehicle provides a pair of right and left frame members (202,203) in the interior of a vehicle body cover so as to extend substantially horizontally between a head pipe (201) and the front end of a seat. Right and left footrest plates (215) are provided outside on the right and left of the vehicle body cover. An engine is provided between the right and left frame members (202,203) with the cylinder axis of the cylinder block being provided so as to extend longitudinally, and the center axis (12d) of a crankshaft is provided so as to extend laterally and to be located above the upper surfaces of the right and left footrest plates (215) as seen in a side view. A balancer shaft is located below the crankshaft, and the crankshaft and the balancer shaft are sandwiched and supported between the upper and lower case halves with their center axes being located on the joining surface.

    摘要： A lower cam carrier (20) is disposed over a cylinder head (10) and a head cover (40) is disposed thereover. The lower cam carrier (20) has, formed as one therewith, an outer frame (22) superposed with the edge peripheral edge (14) of the cylinder head (10), and a bridging part (26) provided between opposing sides of the outer frame (22). The bridging part (26) has a lower bearing (28) for supporting an intake camshaft (30) and an exhaust camshaft (32). The head cover (40) has, formed as one therewith, a flange (42) superposed with the outer frame (22) and a bearing (46) opposing the bridging part (26) inside the flange (42). The bearing (46) has an upper bearing that, together with the lower bearing, supports the intake camshaft (30) and the exhaust camshaft (32).

    摘要： A motor 30 or the like is used to drive a camshaft 22 or the like having a cam 18 or the like to push a valve 12 biased in the closing direction of the valve by a valve spring 17. Between the cam 18 or the like and the valve 12 is present a valve lifter 16 that abuts the cam 18 or the like. The valve lifter 16 includes a top face 16a formed so that when viewed from the axial direction of the camshaft 22 or the like, a tangential direction to the nose tip 18c of the cam 18 or the like inclines with respect to the direction perpendicular to the axial line of a valve stem 14.
