Claims

[Scope of utility model registration request]

An oil chamber is formed between a casing connected to either one of the rotating shaft connected to the front wheel and the rotating shaft connected to the rear wheel, 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. road and
a first pressure regulating valve provided across the pair of oil passages and capable of allowing flow from one oil passage where pressure is generated during forward braking to the other oil passage; and a first pressure regulating valve provided across the pair of oil passages. a second pressure regulating valve that is opposite to the first pressure regulating valve and is allowed to flow at the same pressure as the first pressure regulating valve; and a second pressure regulating valve that is provided across the pair of oil passages and that is allowed to flow even at a pressure lower than that of the first pressure regulating valve and the second pressure regulating valve. a third pressure regulating valve that is allowed to flow and is oriented in the same direction as the first pressure regulating valve; and a cutoff valve that is provided between the third pressure regulating valve and either one of the pair of oil passages and that is capable of blocking the flow. A driving force transmission device for four-wheel drive vehicles.
