PROBLEM TO BE SOLVED: To improve layout and assemblability when a cooling oil pump is contained in the inside of a transmission by attaching an oil pump mechanism on the clutch storage side inner surface of a clutch housing. SOLUTION: An oil pump mechanism 10 is arranged in the inside of a clutch case 6. The oil pump mechanism 10 is equipped with a case member 11 and annular trochoid pumps 12, 13. The case member 11 is fixed to the inside of the clutch case 6 by bolts 23. The trochoid pumps 12, 13 have an outer rotor 12 and an inner rotor 13, and retained in the case member 11. The inner rotor 13 is supported to be integrally fixed to an input shaft 3 projected from a transmission case 2, and the outer rotor 12 is rotatively retained in the case member 11. Hereby, when a cooling oil pump is contained in the inside of a transmission, layout and assemblability can be improved. |
