[Technical Content] A transmission device for a manually operated vehicle includes a transmission gearbox and a generator. The transmission gearbox includes a transmission control member that changes the gear ratio of the manually operated vehicle. The transmission device includes: an electric actuator configured to change the gear ratio; an output unit engaged with the transmission control member and transmitting the driving force of the electric actuator to the transmission control member; and a control device including a control unit configured to control the electric actuator; and a power input unit for inputting electricity generated by the generator. The power input unit is configured to allow detachable connection to terminals for supplying the power to the power input unit. The power input is supplied to at least one of the electric actuator and the control device.
