To provide an endoscope apparatus including a pair of jaws which are mounted an elongated member having a [Problems] both ends, and such that pivotal movement on the ends of one of the end portions. And an end wall extending between the side walls and opposed side walls, extending longitudinally along the jaw, [SOLUTION] Each jaw includes a cup-shaped portion. And a first toothed portion profile, the end walls, opposed side walls includes a second toothed portion profile different from the first tooth section contour. The apparatus includes an actuator member, and a closed position which is the position the ends of the jaws corresponding adjacent the jaws of the other, the ends of the jaws are separated from the jaw of the other are operatively connected to the pair of jaws to move the jaws between, an open position there is provided an actuator member. [Selection] Figure Figure 1【課題】両端部を有する細長い部材、および両端部のうちの一方の端部上で旋回運動するように据え付けられている一対の顎部を具備する内視鏡装置を提供すること。【解決手段】各顎部は、顎部に沿って長さ方向に延びる対向側壁、および側壁の間を延びる端部壁を有する、カップ状部を含む。対向側壁は、第1歯部輪郭を有し、端部壁は、第1歯部輪郭とは異なる第2歯部輪郭を有する。装置はまた、アクチュエータ部材であって、対応する顎部の端部がもう一方の顎部に隣接して位置されている閉位置と、顎部の端部がもう一方の顎部から離間されている開位置と、の間で顎部を動かすように一対の顎部に作用可能に接続されている、アクチュエータ部材を具備する。【選択図】図1
