BRAKING DEVICE

PROBLEM TO BE SOLVED: To provide a braking device that is compact, can be readily operated without the necessity of a strong force, and can realize a safe and smooth braking action.SOLUTION: A braking device includes: a cylindrical internal wall surface that internally forms a cylindrical through hole; a cylindrical external wall surface that houses the internal wall surface in a separated state; and a slit that makes a part of the external wall surface open in a circumferential direction. The braking device includes: a fixing part that houses and fixes a handle in the through hole; a winding part that is housed in a cavity formed between the internal wall surface and the external wall surface, and is constituted by a curved shape in which a diameter from the center of a sectional circle of the through hole continuously varies from a small diameter to a large diameter so as to wind up the other end of a brake wire along the curved shape; and an operating part that is connected to the winding part through the slit and is formed with a projection-like operation lever that is movable along the slit.SELECTED DRAWING: Figure 1 【課題】 コンパクトな形状で、強い力を要することなく、操作が容易で、安全且つ滑らかなブレーキ動作を実現できるブレーキ装置の提供する。【解決手段】ブレーキ装置は、内部に円筒形状の貫通孔を形成する円筒形状の内壁面と、当該内壁面を離隔状態で収容する円筒形状の外壁面と、当該外壁面の一部を円周方向に沿って開放されたスリットと、から構成され、当該貫通孔に前記ハンドルを収容して固定する固定部と、前記内壁面と前記外壁面との間に形成される空洞部に収納され、前記貫通孔の断面円中心からの径が、小径から大径へと連続的に変化する曲線形状で構成され、当該曲線形状に沿って、前記ブレーキワイヤーの他端側を巻き取る巻取部と、前記スリットを介して前記巻取部に接続され、前記スリットに沿って可動性を有する突起状の操作レバーから形成される操作部とを備える。【選択図】図１
