Claims

[Scope of utility model registration request]

(1) In an optical fiber bundle for an endoscope formed by bundling a large number of optical fiber strands used as an illumination light supply means or image transmission means of an endoscope, the outer periphery of the optical fiber strand is made of synthetic resin. At the same time, a large number of these optical fiber strands are bundled together and a pipe member is fitted on both ends of the optical fiber strands to tightly bind both ends of the bundle. 1. An optical fiber bundle for an endoscope, characterized in that a flexible exterior tube is placed over the bundle of optical fiber strands between the members so as to cover the optical fiber strands in a rough state.

(2) The optical fiber strand is characterized in that a protective layer laminated on the outer periphery of the pipe member at one end or both ends is omitted, Optical fiber bundle for mirrors.

(3) The optical fiber bundle for an endoscope according to claim 1, wherein the optical fiber strand has an anti-friction layer laminated on the outermost periphery.
