PROBLEM TO BE SOLVED: To solve such problems that an operation handle is required according to the operation stroke of an operation knob for redesign of the cam and link of obtaining the projection amount of an interlock rod, that redesign of the cam and link is required when the operation stroke of an operation knob changes, and that it is required to design the cam and link of the operation handle depending on the attachment direction of a wiring circuit breaker and the projection direction of the interlock rod.SOLUTION: An operation handle mechanism performing open and close operation of a switching operation knob includes a rotary cam interlocked with the open or close operation of the operation handle to rotate, a reciprocal link linked with the rotary cam and switching operation knob, and displacing the switching operation knob to close or open position by reciprocating in accordance with the rotation of the rotary cam by the operation handle, and the interlock rod having one support end attached to the rotary cam and the other free end attached in the direction abutting on or engaging with an engaging portion provided in a control center housing, reciprocating in accordance with the rotation of the rotary cam and engaging with the engaging portion or disengaging therefrom.SELECTED DRAWING: Figure 4 【課題】インターロックロッドの突出し量を得るためには、操作ノブの動作ストロークにあわせ操作ハンドルのカムとリンクの再設計が必要、操作ノブの動作ストロークに変更があるとカムとリンクの再設計が必要、配線用遮断器の取付け方向とインターロックロッドの突出し方向によっても操作ハンドルのカムとリンクをその都度設計する必要がある。【解決手段】開閉操作ノブを開閉操作する操作ハンドル機構であって、操作ハンドルの開又は閉操作に連動して回動する回動カム、回動カム及び開閉操作ノブにリンクされ、操作ハンドルによる回動カムの回動に応じて往復動し開閉操作ノブを閉又は開のいずれかの位置に変位させる往復動リンク、一方の支持端部が回動カムに取り付けられると共に他方の自由端部がコントロールセンタ筐体に設けた係合部と当接又は係合する方向に取り付けられ、回動カムの回動に応じて往復動し且つ係合部と係脱するインターロックロッドを備えものである。【選択図】図４
