PROBLEM TO BE SOLVED: To provide a balancer assembling structure for an internal combustion engine effectively attaining the vibration control by a pair of symmetrical balancers of an internal combustion engine having a cylinder inclined frontward, preventing the car body from enlarging by shortening the longitudinal width of a crank chamber in the rearward from the rear wheel, ensuring the swinging space of the rear wheel, and facilitating the assembling. SOLUTION: This balancer assembling structure for the internal combustion engine is so formed that a cylinder axis C-C' is inclined in the approximately horizontal direction, a pair of balancers 71, 72 provided in the top/bottom of the crankshaft 25 are arranged within the approximately maximum front/rear width R of the locus of a crank weight 25a, a starter 100 is arranged adjacent to the upper side balancer 71, and auxiliary machines such as an oil pump 85 are arranged adjacent to the lower side balancer 72 in the internal combustion engine for the vehicle arranging the rear wheel adjacent to the rear part of a crank case 21.
