Title:
DIFFERENTIAL GEAR DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2003/091603
Kind Code:
A1
Abstract:
A differential gear device for vehicle, wherein a cylindrical support part (4a) is formed in a carrier, storage holes (4b) are formed in the support part (4a), planetary gears (5) are rotatably stored in the storage holes (4b), one side inner peripheral surfaces and the other side inner peripheral surfaces of the storage holes (4b) in the circumferential direction of the support part (4a) are formed of arc faces having the same curvature radius as the radius of the planetary gears (5), and the centers of the curvatures of the arc faces forming one side inner peripheral surfaces and the other side inner peripheral surfaces of the storage holes (4b) are separated from each other in the circumferential direction of the support part (4a), whereby intervals between one side inner peripheral surfaces and the other side inner peripheral surfaces of the storage holes (4b) can be increased by an amount of separated distances between the curvature centers more than the outer diameters of the planetary gears.
