<p>To provide a transmission driving mechanism of an internal combustion engine (10) where a special transmission driving mechanism for manual operation is not required, the number of parts is reduced, the structure is simple, no maintenance is required and the cost can be reduced. In a transmission driving mechanism (100) of an internal combustion engine which is provided with a transmission that shifts the rotation of a crankshaft (11) and transmits it to an output shaft, and which rotates a shift rotating shaft (111) by an actuator (130) for shift to change the speed of the transmission,
one end of a shift rotating shaft (111) pierces an engine case cover (30), the one end of a shift rotating shaft (111) is protruded outside, and a fitting part (111a) onto which a turning tool (150) is fitted is formed at the protruded end of the shift rotating shaft.</p> |
