ABSTRACT:
A slack absorbing device in the bending operation mechanism of an endoscope. Slack absorbing members are moved along the passage ways of connecting wires as the bending section is bent. Each slack absorbing member has a long groove extending along the direction of movement of said slack absorbing member and a theaded groove formed in a portion of the long groove. Threaded rods connect the ends of the wires extending to the bending section provided in the top end part of the endoscope in such a manner that the threaded rods are moved together with the wires at least when the wires are pulled towards the manual operating section. A part of each threaded groove is cut off so that the threaded rod can engage the threaded groove by aligning the theaded rod, in a direction corresponding to the direction of movement of the wire, and placing it into the groove.
