Patent ID: 11428289

Abstract:
Provided is a rotary damper that can be easily changed in specifications and can be improved in economic efficiency by an existing rotary damper that can be continued to be used. A rotary damper 100 includes a main housing 101. The main housing 101 includes a module mounting portions 108 for detachably mounting the other functional module 200 to 500. The functional modules 200 to 500 respectively have module rotors 206, 306, 406 and 506 which are rotationally driven by receiving a rotational driving force from the outside, and module output portions 206b, 307a, 407a and 507a formed to be connectable to a main rotor 110, in module housings 201, 301, 401 and 501. Further, the functional modules 200 to 500 include input adjustment mechanisms 205, 305, 405 and 505 having a function of changing at least one of characteristics of the rotational driving force and modes of transmission of the rotational driving force, between the module rotors and the module output portions.
