PROBLEM TO BE SOLVED: To provide a brake mechanism capable of extending a length between a fulcrum and a power point by allowing a part of a brake lever to rotate and slide, performing an operation other than a brake wire during an extending operation, providing an appropriate braking effect eve by an index finger alone, and applying a sufficient braking force even during emergency.SOLUTION: This brake mechanism is provided with: a small arcuate part; a connection part; a large arcuate part; and a slide base part. The small arcuate part is elastically and rotatably connected to the large arcuate part around the connection part, the large arcuate part is supported in a half-wrapped or saddle-riding shape with respect to the slide base part, the elastic and slidable configuration enables a length between a fulcrum and a power point to be extended, a steering wheel can be gripped by the other fingers while an index finger is engaged with a circle in the small arcuate part to be operated, and the wide range of braking forces from an appropriate braking force to a strong braking force can be obtained according to scenes and situations.SELECTED DRAWING: Figure 3
【課題】ブレーキレバーの一部が回動、スライドすることができることにより、支点と力点間の長さが延長できて、延長操作時にブレーキワイヤー以外の操作が出来て、人指し指一本でも適宜な制動効果が得られ、緊急時にも充分な制動力を得ることが出来るブレーキ機構を提供する。【解決手段】小弓形部と連結部と大弓形部とスライド基部と基台部とを備え、小弓形部は連結部を中心として大弓形部に弾性的に回動自在に連結され、大弓形部はスライド基部に対し、半包み状、または鞍乗り状に支持され、弾性的に、スライド自在であることにより支点と力点間の長さを延長することが出来て、小弓形部内円に人差し指を掛けた状態で他の指でハンドルを握って操向できて、適宜な制動力から、強力な制動力まで幅広く、場面、状況に応じた制動力を得ることが出来る。【選択図】図3
