DAMPER DEVICE AND FIXTURE
PROBLEM TO BE SOLVED: To provide a damper device and fixture capable of carrying out attenuation force depending on a moving speed, regardless of a position of a movable body.SOLUTION: A hinge 10, as a damper device configured to control a moving speed of a door 1 as a movable body, includes: a rotational shaft 25 configured to rotate along with movement of the door 1; a dynamo 46 configured to generate power by rotation of the rotational shaft 25; a magnetic viscous fluid 64 having a nature that viscosity varies according to a magnetic field, and configured to apply resistance depending on viscosity to the rotation of the rotational shaft 25; and a reaction coil 70 configured to make a magnetic field act on the magnetic viscosity fluid 64 by flow of current generated in the dynamo 46.SELECTED DRAWING: Figure 2
【課題】移動体の位置に関わらず、移動速度に応じた減衰力を作用させることができるダンパ装置及び建具を提供すること。【解決手段】移動体としてのドア１の移動速度を制御するダンパ装置としてのヒンジ１０は、ドア１の移動に連動して回転する回転軸２５と、回転軸２５の回転動作により発電する発電機４６と、磁界に応じて粘度が変化する性質を有し、回転軸２５の回転に対して粘度に応じた抵抗を付与する磁気粘性流体６４と、発電機４６で発電された電流が流れることにより、磁気粘性流体６４に磁界を作用させる抗力用コイル７０と、を備える。【選択図】図２
