Abstract:
1. An endoscopic device comprising: an endoscope, the endoscope including an insertion main body which extends along a longitudinal axis, the insertion main body including a low-strength outer surface portion, and a high-strength outer surface portion which is harder than the low-strength outer surface portion and which thereby has a higher strength against friction than the low-strength outer surface portion, a cavity being formed inside the insertion main body, the cavity being opened with respect to an outside of the insertion main body on the high-strength outer surface; a rotary gear which is attached to the insertion main body and which is located within the cavity of the insertion main body; a rotor which is attached to an outer peripheral direction side of the high-strength outer surface of the insertion main body, the rotor including a gear portion which is provided on an inner peripheral portion of the rotor and which is configured to mesh with the rotary gear in the cavity, the rotor being configured to rotate with respect to the insertion main body about the longitudinal axis when the rotary gear meshed with the gear portion of the rotor rotates; and an attachment unit which is attached to the outer peripheral direction side of the insertion main body and rotor, the attachment unit including:
