ABSTRACT:
A speed change control device for a transmission of an internal combustion engine includes a driving means having an electric motor for rotatably driving a shift drum. The electric motor has a rotation axis orthogonal to an axis of a shift drum. A barrel cam having a cam groove rotates about an axis parallel to that of the electric motor. A transmission rotation member is interlocked and is coupled to the shift drum so as to be rotatable about the axis orthogonal to the rotation axis of the barrel cam. The transmission rotation member is provided with a plurality of engagement pins that selectively engages the cam groove. The resulting configuration allows the electric motor to be disposed inwardly with respect to an outermost side of the body of the internal combustion engine in the direction of the axis of a shift drum and improves the shift accuracy.
