Claims

[Scope of utility model registration request]

A first rotating shaft that transmits driving force to the front wheels of the vehicle, a second rotating shaft that transmits driving force to the rear wheels, and an interposed device between the first rotating shaft and the second rotating shaft. and a hydraulic coupling mechanism capable of transmitting driving force to each other, the hydraulic coupling mechanism is configured as a vane pump type coupling mechanism, and the coupling mechanism has the first rotating shaft and the second rotating shaft. A casing connected to one of the shafts and a rotor connected to the other shaft and housed in the casing are provided, and a large number of rotors are attached to the outer peripheral surface of the rotor and slidably contact the inner peripheral surface of the casing. A vane and a vane biasing mechanism that biases the large number of vanes toward the inner circumferential surface of the casing are provided, and the axial clearance between the rotor and the casing is set to a distance that does not break the oil film. A drive coupling device for four-wheel drive, characterized in that: −
