ABSTRACT:
A rotary damper with a directional property is disclosed which is capable of being simplified in structure, manufactured with a low cost, and stably and precisely operated. The rotary damper is constructed in such a manner that a clutch spring is interposed between a revolving shaft and a rotor to selectively carry out the integral rotation of the rotor with the shaft or the stop of the rotor independent from the shaft.
