FIG7 is a block diagram showing a modified example of the manner of connection of an electric motor
The manner of connection of the electric motor M to the output shaft 7 may be different from that described above. FIG7 is a block diagram showing a modified example of the manner of connection of the electric motor M. In a transmission 105 shown in FIG7, gears 9A provided on the input shaft 6 are fitted on the input shaft 6 so as to corotate with the input shaft 6, while gears 9B and 9C provided on the output shaft 7 are rotatably fitted on the output shaft 7 so as to rotate independently of the output shaft 7. The gears 9B and 9C provided on the output shaft 7 are constantly in mesh with the gears 9A provided on the input shaft 6. Dog rings 42 provided on the output shaft 7 are fitted on the output shaft 7 so as to corotate with the output shaft 7. Upon rotation of a shift drum 40, a shift fork 41 moves along the output shaft 7 to cause the dog ring 42 to engage with one gear selected from the plurality of gears 9B and 9C, and the engaged gear corotates with the output shaft 7. The electric motor M is connected to the gear 9C (rotating member) which is one of the gears 9B and 9C provided on the output shaft 7 via the second power transmission mechanism 17, so that power is constantly transmitted from the electric motor M to the gear 9C. When the dog ring 42 is not engaged with the gear 9C, the gear 9C rotates independently of the output shaft 7. Thus, power of the electric motor M is transmitted to the input shaft 6 via the gear 9C and gear 9A, and the resulting rotation of the input shaft 6 is transmitted to the output shaft 7 via the gear 9B corresponding to the desired gear position and engaged with the dog ring 42. That is, with the configuration of FIG7, the electric motor M can transmit power to the input shaft 6 through a route different from the route through which power from the engine E is transmitted to the input shaft 6. When the dog ring 42 is engaged with the gear 9C, the gear 9C corotates with the output shaft 7. Thus, power transmitted from the electric motor M to the gear 9C can be directly transmitted to the output shaft 7.
