BRAKING DEVICE
To provide a braking device capable of reducing braking force applied during low speed rotation while obtaining sufficient braking force at high speed rotation of a rotary body.SOLUTION: A braking device includes: a fixed body 12; a rotary body 14 rotatably provided relative to the fixed body 12; a conductive member 16 and a magnet 18 which are disposed to face each other in a rotational axis direction or a radial direction of the rotary body 14, and one of the conductive member 16 and the magnet 18 being rotatably provided integrally with the rotary body 14, and other of them being provided on the fixed body 12; and an interval adjusting mechanism 20 capable of adjusting an interval so that, as the rotational speed of the rotary body 14 increases, the interval between the conductive member 16 and the magnet 18 in an opposing direction decreases.SELECTED DRAWING: Figure 2
【課題】回転体の高速回転時には十分な制動力を得つつ、その低速回転時に付与される制動力を小さくできる制動装置を提供する。【解決手段】固定体１２と、固定体１２に対して回転可能に設けられる回転体１４と、回転体１４の回転軸方向又は径方向に対向して配置される導電性部材１６及び磁石１８であって、導電性部材１６及び磁石１８の一方は回転体１４と一体的に回転可能に設けられ、それらの他方は固定体１２に設けられる導電性部材１６及び磁石１８と、回転体１４の回転速度が大きくなるほど、導電性部材１６と磁石１８の対向方向での間隔が小さくなるように、その間隔を調整可能な間隔調整機構２０と、を備える。【選択図】図２
