摘要： An endoscope includes a curving operation portion which performs a curving operation of a curving portion by rotating around a pivot shaft in a first rotation direction and in a second rotation direction opposite to the first rotation direction from a neutral position where the curving portion is in a non-curved neutral state, a first operation wire which is pulled by the curving operation in the curving operation portion to curve the curving portion in the second curving direction, and a second operation wire which is pulled by the curving operation in the curving operation portion to curve the curving portion in the first curving direction. The endoscope includes a wire crossing portion in which the second operation wire crosses the first operation wire, and a movement regulating portion which regulates the movement of the wire crossing portion from within the operation portion into the insertion portion.
