PURPOSE:To easily obtain an operation condition to meet a navigation purpose by using a system in which an auxiliary input shaft connected to an auxiliary prime mover is provided to a speed reduction and reversing device provided with an input shaft directly connected to engine side, and an output shaft is connected through a clutch to the auxiliary input shaft. CONSTITUTION:An auxiliary intermediate shaft 16 and an auxiliary input shaft 17 are provided in parallel on the side of an output shaft 3 turning through an input shaft (not illustrated), an input gear (not illustrated), and an output gear 7 by the rotation of a main prime mover. The auxiliary input shaft 17 is turned through a belt 22 and pulley 21 by the rotation of an auxiliary prime mover (not illustrated). Also, an auxiliary intermediate gear 23 engaged with the output gear 7 is loosely fitted into the auxiliary intermediate shaft 16, and an auxiliary input gear 24 engaged with the auxiliary intermediate gear 23 is loosely fitted to the auxiliary input shaft 17. A clutch claw 24a constituting a clutch in conjunction with the clutch claw 25a of a clutch dog 25 is formed on the side of the gear 24. By operating the dog 25 through a shifter 33 by a handle shaft 38, the connection and disconnection between the shaft 17 and the gear 24 can be controlled. |
