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. two sub-passages that communicate these oil passages, a check valve provided in each sub-passage that only allows pressure oil to flow in opposite directions, and a check valve on the side that allows pressure oil to flow during operation. A driving force transmission device for a four-wheel drive vehicle, comprising an orifice provided in a sub-passage for suppressing the flow of pressure oil, and an orifice provided in another sub-passage and having a larger throttle opening than the orifice.
