PURPOSE:To share shift cams and driven bodies of both double type screw propellers whose rotating directions are opposite to each other by forming the shift cams and the driven bodies so that they can be connected to clutch bodies in assembled positions where the shift cams and the driven bodies holding the shift cams are turned over top-to-bottom. CONSTITUTION:With both double type screw propellers whose rotating directions are opposite to each other, shift cams 35 and driven bodies 37 holding the shift cams are turned over top-to-bottom to each other, and thereby the phase with which the driven body 37 of one screw propeller is driven by the shift cam 35, and the phase with which the driven body 37 of the other screw propeller is driven by the shift cam 35 can be formed so as to be displaced 180 degrees to each other. As a result, even if the operating direction of a shift operating unit is the same, the shifting directions of the driven bodies 37 and clutch bodies can be opposite to each other, and propeller shafts of both screw propellers can rotate in the opposite directions. When the double type screw propelling device is constructed, the shift cams 35 and the driven bodies 37 can be formed to be used in common. |
