The endoscope for obtaining a braking force to reliably maintain the bent state of the bending portion that requires the competence large bending for bending, it is located outside the side of the support plate, the axis of the first bearing member slidable in the direction, and the adjusting member to adjust the gap of the friction member and the members are disposed pressing member, holding the sliding rotation is arranged by screwing to the support plate, the contact state of the adjustment member It comprises a, positioning a plurality of members that can be moved away from the support panel and the adjusting member by varying, for adjusting the braking force applied to the cylindrical member of the friction member.湾曲させるために大きな曲げ力量を必要とする湾曲部の湾曲状態を確実に維持する制動力を得るための内視鏡であって、支持盤の外方側面に配置され、第1軸受部材の軸方向に摺動自在で、回動押さえ部材、摺動押さえ部材及び摩擦部材が配置される間隙を調整可能にする調整部材と、支持盤に螺合により配置され、調整部材との当接状態を変化させることによって該調整部材を支持盤から離間させて、摩擦部材の円筒部材に対する制動力を調整する複数の位置決め部材と、を具備する。
