PROBLEM TO BE SOLVED: To improve maneuverability by disposing the rear side cylinder assembly of a four-cycle V-type engine in space between main frames and disposing a coupled surface of a head cover of the rear side cylinder assembly and a cylinder head, so as to be inclined obliquely downward toward a rear wheel side. SOLUTION: A V-type engine 3 is provided with a cylinder head 16 covered with a head cover on a head part of a cylinder block 15. A car body frame 2 of a V-type engine 3 mounted part is provided with a pair of left and right main frames 2a extending to the rear side in parallel each other after the main frames 2a are expanded and opened in left and right directions from a head pipe 7. The coupled surface of the head cover of a front side cylinder assembly 18F and the cylinder head 16 is inclined obliquely downward toward a front wheel side 8 for the coupled surface of the cylinder head 16 and the cylinder block 15, and the front side cylinder assembly 18F is made to approach the front wheel 8 side. A rear side cylinder assembly 18R is disposed in space between the main frames 2a and a coupled surface of a head cover of the rear side cylinder assembly 18R, and the cylinder head 16 is inclined obliquely downward toward a rear wheel 13 side. |
