<p>In an internal combustion engine for a straddle type vehicle on which the internal combustion engine (20) is mounted in such a way as to be supported by a vehicle body frame (2), a plurality of stud bolts (71, 72) which are implanted by allowing implanting screw portions (71a, 72a) provided at lower ends thereof, to be screw-threaded into a crank case (21), are configured to pass through a cylinder block (22) and a cylinder head (23) which are piled in order on the crank case (21). Nut members (71N, 72N) are screwed on and fastened to upper screw portions (71b, 72b) of the stud bolts (71, 72) which pass through and project from the cylinder head (23). A too! engaging portion (71c, 72c) with which a tool is engaged to rotate the stud bolt (71, 72) is formed at an upper side of the upper screw portion (71b, 72b) of the studbolt(71,72).
