Claims

[Scope of utility model registration request]

The vehicle has a rotor fixed to the power shaft of the vehicle, a stator surrounding the rotor, and an oil seal attached to the part where the power shaft passes through the stator, and an oil drain pipe is connected to the retarder outlet on the outer periphery of the stator. an oil cylinder to which the intermediate port is connected through the oil cylinder; an oil pushing piston and a circuit closing piston with a return spring provided in the oil cylinder; and an oil cylinder at one end of the oil cylinder in order to operate the oil pushing piston. A connected air supply pipe, an oil supply pipe connecting an end port that communicates with and is cut off from the intermediate port by actuation of the circuit closing piston and a retarder inlet in the intermediate portion of the stator are provided. A retarder device for a vehicle, characterized in that a lubricating oil circuit is provided, comprising an oil passage from the retarder outlet to the oil seal, and an oil passage from the oil seal to the retarder inlet.
