Document Type and Number:
Japanese Patent JP2002130426
Kind Code:
A
Abstract:
To enhance durability, and to simplify the shape of a pump cover by arranging a clutch drum support part on a stator shaft.
An internal teeth gear 6 and an external teeth gear 7 are housed in a pump housing 2 in a meshing state. The stator shaft 10 is composed of a press-in shaft part 11 pressed in a shaft inserting fitting hole 4A of the pump cover 4, a stator support part 12 for supporting a stator 22A of a torque converter 22, and the clutch drum support part 13 for rotatably supporting a clutch drum 27A of a reverse clutch 27. Thus, high strength can be imparted to the clutch drum support part 13, and there is no need to arrange a drum supporting boss part in the pump cover 4 so that the shape can be simplified.
