用新案登録請求の範囲第1項に記載の内視鏡。[Scope of Claim for Utility Model Registration] (1) In an endoscope that connects a flexible tube of an insertion section and a curved tube, the distal end portion of the core material of the flexible tube and the rear end portion of the core material of the curved tube. What is claimed is: 1. An endoscope comprising: a coupling means for directly fitting the two parts and coupling the two fitting parts within the wall thickness of the two fitting parts. (2) The coupling means is formed by forming an elastic cut-and-raised piece on one of the tip end portion of the core material of the flexible tube and the rear end portion of the core material of the curved tube that fits therein, and the other portion. The endoscope according to claim 1, wherein the endoscope has an engaging hole into which the cut-and-raised piece fits and locks. (3) The coupling means forms a first engagement hole with a small diameter in one of the tip end portion of the core material of the flexible tube and the rear end portion of the core material of the curved tube that fits therein, and the first engagement hole has a small diameter in the other side. A second engagement hole with a larger diameter is formed at a position corresponding to the first engagement hole, and a stepped engagement pin is formed between the first engagement hole and the second engagement hole. The endoscope according to claim 1, characterized in that the endoscopes are tightly fitted together.
