Plural contents such as a light guide and a forceps tube, which are inserted into an insertion part of an endoscope, are connected with each other via an elastic member such as thin wall tubes, etc. at one or more positions in the insertion part. The elastic member changes its form with the dislocation of the contents in the longitudinal direction of the insertion part resulting from the bending of the insertion part. If the insertion part is straightened, the contents are restored to their original positions by the restitutive force of the elastic member.
