PROBLEM TO BE SOLVED: To provide a pump mounted type speed change gear capable of reducing time and effort to required for the work to change a change gear ratio.SOLUTION: Plural sets of gear trains 17, and 18 for changing the speed of rotation at an input shaft 15 side and transmitting the speed of rotation to an output shaft 16 side are arranged in a case 14. Each of the gear trains 17, and 18 comprises a plurality of gears 22, 23, 24 and 25 engaged with each other. The case 14 is divided into a plurality of split case bodies 32, and 33. Each of the gear trains 17, and 18 is stored in split case bodies 32, and 33, which are different from each other for each of the gear trans 17, and 18. The split case bodies 32, and 33 can be separably connected to other split case bodies 32, and 33 under a state in which the gear trains 17, and 18 are stored. |
