Zusammenfassung:PROBLEM TO BE SOLVED: To provide a bicycle pedal capable of reducing a force required when performing detachment operation so as to satisfy a conflicting requirement; that is, while a strong spring force is essential when shoes are mounted thereon, a weak spring force is preferable when performing the detachment operation because the strong force hinders the detachment operation.SOLUTION: There is provided a so-called step-in/turnout type pedal including a fixed locking claw 3 in front of, and movable locking claws 4a and 4b in rear of, a pedal body. The movable locking claws are mounted side by side in a pedal axial direction as a plurality of independent movable locking claws, and each movable locking claw is energized upward by an individual energizing member. In the detachment operation of the shoes, the spring force of the movable locking claws to be rotated downward is reduced to a half or less, the movable locking claws are rotated with a small force, locking of a cleat is released, and the shoes can be detached. 【課題】装着時には強いバネ力が必須であり、他方強いバネ力は離脱操作の障害になるので弱いバネ力が好ましいという相反する要求を満たすために、離脱操作時に必要とする力を低減することができる自転車用ペダルを提供する。【解決手段】ペダルボディの前方に固定係止爪3を、後方に可動係止爪4a、4bを備えたいわゆるステップイン・ターンアウトタイプのペダルであって、前記可動係止爪を独立した複数の可動係止爪としてペダル軸方向に並列して取り付け、各可動係止爪はそれぞれ個別の付勢部材によって上向きに付勢する。靴の離脱操作においては、下方に回動させるべき可動係止爪のバネ力は1/2以下に減少することとなり、小さな力で可動係止爪を回動させ、クリートの係止を解除し、靴を離脱することができる。【選択図】図7
