The endoscope 1 pulls the second operation wire by rotating the bending operation lever 10 in the first rotation direction, and rotates the bending operation lever 10 in the second rotation direction. The first setting state in which one operation wire 23a is pulled, or by turning the bending operation lever 10 in the first rotation direction, the first operation wire 23a is pulled and the bending operation lever 10 is moved to the first position. Bending for setting the relationship between the turning direction of the bending operation lever 10 and the bending direction of the bending portion 5 to the second setting state in which the second operation wire 23b is pulled by turning in the second turning direction. A direction setting unit 40 is provided. The bending direction setting unit 40 includes a wire intersecting portion 41 where the first operation wire 23a and the second operation wire 23b intersect in the second setting state. The endoscope 1 also includes a movement restricting portion 36 that restricts the movement of the wire crossing portion 41 from the inside of the operation portion 3 to the inside of the insertion portion 2.内視鏡１は、湾曲操作レバー１０を第１の回動方向に回動することにより第２の操作ワイヤが牽引され、湾曲操作レバー１０を第２の回動方向に回動することにより第１の操作ワイヤ２３ａが牽引される第１の設定状態、又は、湾曲操作レバー１０を第１の回動方向に回動することにより第１の操作ワイヤ２３ａが牽引され、湾曲操作レバー１０を第２の回動方向に回動することにより第２の操作ワイヤ２３ｂが牽引される第２の設定状態に、湾曲操作レバー１０の回動方向と湾曲部５の湾曲方向との関係を設定する湾曲方向設定部４０を備える。湾曲方向設定部４０は、第２の設定状態の際に第１の操作ワイヤ２３ａと第２の操作ワイヤ２３ｂとが交差するワイヤ交差部４１を備える。また、内視鏡１は、操作部３の内部から挿入部２の内部へのワイヤ交差部４１の移動を規制する移動規制部３６を備える。
