Abstract:
A damper is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations. This damper 1, provided with a casing 1A linked to a first object and a rotating part 1B linked to a second object rotatably attached to the first object, damps rotation in either the direction closing or the direction opening the second object, and is provided with a sensor 20 which detects prescribed change in the external environment in the damper 1 or around the damper 1, and a control unit 21 which externally communicates, over a communication network, information relating to the change in the external environment detected by the sensor 20, wherein the sensor 20 is configured from at least one of: a rotation sensor for detecting the number of revolutions of the rotating part 1B; a sound sensor for detecting sound during rotations of the rotating part 1B; a temperature sensor for detecting temperature; and a torque sensor for detecting torque on the basis of friction during rotation of the rotating part 1B.
