SPEED CONTROLLER AND BLIND DEVICE
To provide a speed controller capable of increasing the degree of freedom in the setting range of a braking torque.SOLUTION: A speed controller 6 of the present invention is configured such that a pressing force that varies depending on the moving direction of a cord (for example, the lifting code C1, C2, C3) is applied to the cord in a sandwich manner for limiting the moving speed of the cord moving in one direction in order to brake the moving speed of a shielding member (for example, the slat of a horizontal blind) in a blind device to a specific value or less, the speed controller being configured to include: a pair of roller portions 632 and 642 which are journaled by respective roller shafts and which sandwich the cord therebetween, at least one of the roller portions being allowed to move close to or away from the other depending on the moving direction of the cord; and a braking portion 6a for applying a braking torque due to the centrifugal force to one (or both) of the roller shafts 642 of the pair of roller portions 632 and 642, the roller shaft 642 being positioned on the outer peripheral side of a carrier 65 with external teeth forming a part of a brake portion 6a.SELECTED DRAWING: Figure 7
【課題】制動トルクの設定範囲の自由度を高めることが可能な速度調整装置を提供する。【解決手段】本発明の速度調整装置６は、コード（例えば昇降コードＣ１，Ｃ２，Ｃ３）の移動方向に応じて異なる押圧力で挟み込み一方向に移動するコードの移動速度を制限して遮蔽装置における遮蔽材（例えば横型ブラインドのスラット）の移動速度を一定値以下に制動するよう構成され、当該コードを挟み込み、当該コードの移動方向に応じて少なくとも一方に近接又は離間可能にそれぞれのローラー軸で軸支される一対のローラー部６３２，６４２と、一対のローラー部６３２，６４２のいずれか一方（又は双方）のローラー軸６４２に対し遠心力による制動トルクを作用させるブレーキ部６ａとを備えており、ローラー軸６４２がブレーキ部６ａの一部を構成する外歯付キャリア６５の外周側に位置するよう構成されている。【選択図】図７
