Abstract
A transmission device for an internal combustion engine for preventing components thereof from being damaged for making the components smaller in size and weight, reducing a load and a time required to shift gear positions for increased operability and for reducing overall size and weight. A transmission device for an internal combustion engine includes a shift drum angularly movable by a star-shaped drum plate that is turned when a change spindle is turned and a stopper roller for limiting the star-shaped drum plate against turning movement. The star-shaped drum plate includes peaks corresponding to a plurality of gear positions and valleys interposed between the peaks. A selected one of the valleys includes a curved wall for being more gently contacted by the stopper roller than curved surfaces of the other valleys which are contacted by the stopper roller.
