して施す。 To explain its operation, the device of the present invention is made, for example, as shown in the first diagram, and in this case, it is equipped with a multi-speed transmission, which is the first transmission 2, and has a direct coupling or overtop function as a whole, and an emergent engine function. It has many functions added, but if necessary, for example, if you do not need the emergent function,
It is sufficient to remove the outermost third transmission 11 and, if the overtop function is not required, to remove the inner second transmission 10. To further explain this, the second transmission 10 and the third transmission 11 are made by longitudinally extending the input shaft 5 and output shaft 6 of the first transmission 2, and the third transmission 11 When the input shaft 5 is not required, the input shaft 5 is extended to the second input shaft 12.
By using this and removing the third output shaft 18, the corresponding extension can be reduced to obtain, for example, the state shown in the second figure. In this case, the outer periphery of the case 20 may be left as is, but it may be made more or less flattened as shown in the figure. Furthermore, the second
The case where the transmission 10 is not required is also substantially the same, and by using the input shaft 5 and the output shaft 6 without extensions, the corresponding extensions of the shafts 12 and 13 are reduced, for example, as shown in the third figure. Get to the state. In this case, the outer case 15 is the right half 15 described above.
b is removed to leave only the left half portion 15a, and the case 20 described above is attached to the open end of the half portion 15a as is or after being flattened.

簡単にする等の効果を有する。 In this way, according to the present invention, the second transmission for direct coupling or overtop is placed on the side of the first transmission, which is a multi-speed transmission, and the third transmission for emergent transmission is sequentially placed on the side thereof. If the third transmission is removed while leaving the second transmission, which is more or less necessary, there is no need to make any changes to the second transmission and the first transmission. 2
When the transmission is removed, there is no need to make any changes to the first transmission, and thus it is possible to increase common parts for diversification of functions, improve mass productivity, and reduce costs. Since the third transmission is located on the outermost side, the gear on the input side is made on the input shaft itself, but it is the outermost end of the extension of the input shaft in the first transmission, so the input shaft and the extension are the whole. However, each reduction gear is housed separately in each case and is pivotally supported by each case, and there is no reduction in the rigidity of the third transmission or even the second transmission. This eliminates the need for a separate shaft support even if added, and has the effect of simplifying the configuration.
