Claims

[Scope of utility model registration request]

An oil cylinder comprising a rotor fixed to a power shaft of a vehicle and a stator surrounding the rotor, and an intermediate port connected to a retarder outlet on the lower outer periphery of the stator and disposed below the retarder outlet. , an oil pushing piston with a return spring provided in the oil cylinder, and an air supply pipe connected to one end of the oil cylinder to operate the oil pushing piston;
An oil supply pipe is provided that connects an end port that communicates with the intermediate port and a retarder inlet in the intermediate part of the stator, and the oil supply pipe is connected to open the oil supply pipe, shut off the oil supply pipe, and connect the retarder to the retarder inlet. 1. A retarder device for a vehicle, characterized in that a switching valve for switching between opening and opening an inlet to the atmosphere is interposed, and an atmosphere communication port is provided in a portion of the stator near the power shaft.
