    • [Problem] To eliminate the usage of the ball bearing at the portion rotatably supporting the shift drum by equalizing the load generated during upshifting operation and the load generated during downshifting operation so that the sense of discomfort of the driver is eliminated, in a variable speed gear for an internal combustion engine in which change gear operation is performed by rotating a star plate fixed to a shift drum by rotating a change spindle and a stopper roller is pressed against and engaged with a recess on the outer periphery of the star plate.
      [Solving Means] The center of rotation of the aforementioned stopper roller is disposed on a straight line connecting the center of rotation of the aforementioned change spindle and the center of rotation of the aforementioned shift drum, and a pressing force toward the center of rotation of the aforementioned shift drum is exerted on the stopper roller.
