Furthermore, a torque response mechanism is arranged coaxially with the resultant shaft on the downstream side of the one-way clutch of the manual drive system, so when the crankshaft is reversed, the rotation is not transmitted to the torque response mechanism and the electric motor, and the pedal is reversed with a light force. Can be done. For this reason, it becomes easy to adjust the pedal position to a position where it is easy to start when starting.

発明によればそのようなこともない。A torque responsive mechanism is provided on one side in the vehicle width direction with a driven gear on the resultant shaft side of the electric drive system gear train interposed therebetween.
If the transmission systems of the rear wheels are separately arranged on the other side in the width direction of the vehicle body, it is suitable for downsizing the entire drive system (claim 2). In particular, when the torque response mechanism is arranged longer in the longitudinal direction of the resultant shaft across the driven gear, the resultant shaft and the driven gear become larger, which leads to an increase in the size of the drive system. Nothing like that.
