摘要:
A bending control mechanism for an endoscope, provided with a control body and a bendable section including an insertion section, the bending control mechanism includes a pulley which is rotatably provided in the control body, and a wire connected between the pulley and the bendable section. An outer peripheral profile of the pulley, onto which the wire is wound, includes a non-circular section including a small-radius section having a small radius from a rotational axis of the pulley, and a large-radius section having a radius from the rotational axis that is larger than the small radius. The wire is wound onto the large-radius section at an initial winding stage at which the bendable section is at a non-bending position. The wire is wound onto the small-radius section at a stage where the bendable section is bent by a maximum amount.
