Claims

[Claims for Utility Model Registration] A swinging operation structure for a fiberscope, which has at least an image guide and a light guide inserted through it, and a striated body whose tip part can swing. A grip body that can be gripped with one hand through which the guide passes is provided at the intermediate portion to the proximal end portion of the filament body, and a pinion gear is provided inside the grip body, and a grip body that meshes with the pinion gear in opposite directions in the longitudinal direction is provided inside the grip body. First and second rack gears that reciprocate are installed inside, and two swinging wires inserted from the tip of the grip body are fixed to the first and second rack gears, respectively. A swing operation structure characterized in that a rotary operation wheel that can be operated with one hand and is interlocked with a pinion gear is attached to the grip body.
