Claims

[Scope of utility model registration request]

In a hydraulic retarder that is interposed in a power transmission system, includes a stator and a rotor, and absorbs energy on the rotor side using hydraulic oil supplied between the two as a medium, a row of blades forming each chamber of the stator is used. A portion of the blades can be rotated in the circumferential direction, and when the retarder is not in operation, the blade rows are shifted by the spring force of the spring to allow adjacent chambers to communicate with each other, and when the retarder is in operation, the hydraulic pressure of the hydraulic oil is applied to the spring force of the spring. A retarder characterized in that the blade rows are rotated against each other to align the blade rows to form mutually independent chambers.
