PROBLEM TO BE SOLVED: To provide a pump device which enables the clutch device and the brake device of a speed change gear to be easily maintained and inspected, and which enables the case to be commonly used for a plurality of different types of speed change gears.SOLUTION: This pump device includes the speed change gear 10 which changes the rotational speed of an input shaft 13 rotatingly driven by a prime mover 11 by a speed change mechanism 14 and outputs the changed speed from an output shaft 15 to a pump shaft 4. The speed change mechanism 14 and the output shaft 15 of the speed change gear 10 are installed in an output side case 25. The input shaft 13 is divided into a first input shaft 17 on the prime mover 11 side and a second input shaft 18 on the speed change mechanism 14 side. A clutch device 31 for engaging and disengaging the transmission of a rotating force from the first input shaft 17 to the second input shaft 18 and the brake device 32 for restraining the rotation of the second input shaft 18 are installed on the outside of the output side case 25. |
