Abstract: An endoscope includes a first breakable portion provided between a part of an outer peripheral surface of a distal rigid section main body and a second inner peripheral surface, and including a fragile portion which is formed in a concaved-shape and which is more easy to break than any other part of the outer peripheral surface except for thereof. The endoscope includes a second breakable portion provided between a first inner peripheral surface and the second inner peripheral surface, and a third breakable portion provided between the first inner peripheral surface and a part of the outer peripheral surface of the distal rigid section main body, which differs from the fragile portion.

Abstract: An endoscope including an operation portion, an insertion portion pivotable relative to the operation portion, and a rotation knob to pivot the insertion portion about an axis of the insertion portion, includes: an insertion portion neutral position indicating portion, provided on an outer circumferential face of the rotation knob, configured to indicate a neutral position; and an indication ring, provided at the operation portion configured to include an operation portion neutral position indicating portion linearly aligned with the insertion portion neutral position indicating portion in an axis direction and indicating that the insertion portion is positioned at a neutral position, and two rotational angle indicating portions provided so as to be apart from the operation portion neutral position indicating portion in a circumferential direction, each of the two rotational angle indicating portions indicating rotation of the insertion portion.
