Claims

[Scope of utility model registration request]

An oil chamber is formed between a casing connected to either one of the rotating shafts connected to the front wheels and the rotating shafts connected to the rear wheels, and the casing rotatably housed within the casing. and a rotor connected to the other rotating shaft, and at least a pair of oils each communicating with the oil chamber through the casing and through which pressure oil flows in an amount corresponding to the rotational speed difference between the two rotating shafts. a one-way valve provided in each of these sub-passages to allow pressure oil to flow in the opposite direction to the other, and a one-way valve that allows pressure oil to flow in the opposite direction to the other one, a first orifice installed in one of the auxiliary passages on the side where the flow is allowed; a second orifice installed in the other auxiliary passage and having a larger throttle opening than the first orifice; and a second orifice installed in the other auxiliary passage. A driving force transmission device for a four-wheel drive vehicle, comprising a switching valve that closes the other auxiliary passage when traveling backward.
