One that switches between forward and second speeds (for example, see Japanese Utility Model Publication No. 61-14690).

In the above-mentioned conventional forward two-speed device, in the device in which a forward two-speed shaft is additionally provided, the two forward-side shafts and the reverse shaft are arranged side by side from above the output shaft. As a result, there is a disadvantage that the speed reduction / reversing machine case bulges to the side and becomes large. For example, as shown in FIG. 3, when the reverse shaft (51) is disposed immediately above the output shaft (52) and the forward first speed shaft (53) and the forward second speed shaft (54) are disposed on the left and right sides thereof, Compared to the case of only the speed, there is an inconvenience that the width on the left and right is increased by an amount corresponding to the arrangement of the second forward speed shaft (54). In other words, in the case of the standard machine having only the first forward speed, the size of the broken line in the drawing is sufficient, but the standard machine expands to the position of the solid line. For this reason, there is a drawback in that the bulge portion hinders installation on the engine stand, and a troublesome operation such as processing the engine stand upon installation is required.

In particular, in the case of a high-speed ship, the bottom of the ship has a V-shape, and in this case, the bottom of the ship has to be inflated, which is extremely disadvantageous for the high-speed ship.

[0007] Recently, in order to reduce the load on the engine, there is a tendency to use the engine at a high speed by increasing the reduction ratio. However, in this case, the reduction gear becomes large, and the size of the reduction gear increases. This may result in a case where the device cannot be actually mounted.

On the other hand, in the case where the planetary gear mechanism is arranged on the output shaft portion, the area around the output shaft arranged below the input shaft becomes larger, and especially in the case of the above-mentioned high-speed ship, it cannot be mounted. There is a problem.
