Title:
MANIPULATION MECHANISM, ENDOSCOPE, AND MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2018166675
Kind Code:
A
Abstract:
To provide a manipulation mechanism capable of reliably fixing an operation wire to an operating object member, endoscope, and manufacturing method.SOLUTION: The manipulation mechanism according to one embodiment of the present invention, includes a sleeve member that is caulked into such a caulked shape as to retain a twisting shape of a plurality of wire strands of an operation wire, so that the sleeve member is caulked, with the wire strands retained in an original line contact state. This configuration can prevent the wire strands from getting into a point contact state and being damaged with each other so as to improve tension strength and bending durability of the operation wire, and reliably fix the operation wire to an operating object member. Further, the sleeve member externally fitted around the operation wire is fixed to the operating object member so as to dispense with another member for fixing, thereby downsizing the fixing member.SELECTED DRAWING: Figure 19
