- a front end body provided on a front end of the elongated insertion portion; and,
- a detachable front end cap which alone covers said front end body said detachable front end cap having an easily deformable member having a relatively high resiliency and a deformation restricting member having a relatively low resiliency with respect to said easily deformable member;
- wherein said easily deformable member and said deformation restricting member are interconnected to form said front end cap.
- 2. An endoscope according to claim 1, wherein said front end body is provided, on the front end of the insertion portion, with a view window, and wherein said front end cap is provided with an opening corresponding to the view window, so that the view window can be exposed outside of said endoscope through the opening.
- 3. An endoscope according to claim 1, wherein said front end body is provided, on the side surface thereof, with a view window, and wherein said front end cap is provided with an opening corresponding to the view window, so that the view window can be exposed to the outside through the opening.
- 4. An endoscope in accordance with claim 1 wherein said easily deformable member and said deformation restricting member are provided with mating hook portions adapted to interconnect with each other to form said front end cap.
- 5. An endoscope having an elongated insertion portion, comprising:
- a front end body provided on a front end of the elongated insertion portion; and,
- a detachable front end cap which alone covers said front end body,
- wherein said front end cover is comprised of a cover portion which covers the front end body and an engaging portion which engages with the front end body, and,
- wherein said engaging portion is made of a relatively easily deformable member having a high resiliency, and said cover portion being made of a deformation restricting member having a relatively lower resiliency than the easily deformable members and wherein said engaging portion and said cover portion are interconnected to form said front end cover.
- 6. An endoscope according to claim 5, wherein said front end body is provided, on the front end of the insertion portion, with a view window, and wherein said front end cap is provided with an opening corresponding to the view window, so that the view window can be exposed to the outside through the opening.
- 7. An endoscope according to claim 6, wherein said front end body is provided on the front end portion thereof with an air supply passage and a water supply passage, and wherein said front end cap is integrally provided with a nozzle portion oriented toward the view window and connected to the air supply passage and the water supply passage when the front end cap is attached to the front end body.
- 8. An endoscope according to claim 7, wherein said front end body and said front end cap are both cylindrical.
- 9. An endoscope according to claim 7, wherein said front end cap is provided on the outer peripheral surface thereof with at least one engaging recess which can be engaged by a tool which is used to remove the front end cap from the front end body.
- 10. An endoscope according to claim 9, wherein said engaging portion is provided on the inner peripheral surface thereof with an engaging projection corresponding to the engaging recess and extending in the axial direction, said front end body being provided with an axially extending engaging groove in which the engaging projection of the engaging portion can be engaged when the front end cap is attached to the front end body.
- 11. An endoscope according to claim 5, wherein said front end body is provided, on the side surface thereof, with a view window, and wherein said front end cap is provided with an opening corresponding to the view window, so that the view window can be exposed to the outside through the opening.
- 12. An endoscope according to claim 11, wherein said front end body is provided with an air supply passage and a water supply passage, both opening toward the view window, and wherein said front end cap is integrally provided with a nozzle portion connected to the air supply passage and the water supply passage when the front end cap is attached to the front end body.
- 13. An endoscope in accordance with claim 5 wherein said easily deformable member and said deformation restricting member are provided with mating hook portions adapted to interconnect with each other to form said front end cap.
- 14. An endoscope having an elongated insertion portion to be inserted in a human body, comprising:
- a front end body provided on a front end of the elongated insertion portion;
- a detachable front end cap which is detachably attached to the front end body to cover the front end body; and,
- a view window which is provided on a side surface of the front end portion and is exposed to the exterior of said endoscope through the front end cap;
- wherein said front end cover further comprises an easily deformable member having a high resiliency; and,
- a deformation restricting member having a lower resiliency than the easily deformable member, said easily deformable member being supported, at least at the portion thereof that engages with the front end body, by the deformation restricting members said front end cap being provided with at least one slit which enables said front end cap to elastically deform when the front end cap is attached to the front end body.
- 15. An endoscope according to claim 14, wherein said front end body is provided with an air supply passage and a water supply passage, both opening toward the view window, and wherein said front end cap is integrally provided with a nozzle portion connected to the air supply passage and the water supply passage when the front end cap is attached to the front end body.
- 16. An endoscope according to claim 14, wherein said front end cap and the deformation restricting member are cylindrical and wherein said at least one slit of said front end cap is provided on said deformation restricting member on a portion thereof corresponding to the engaging portion of the front end cap.
- 17. An endoscope having an elongated insertion portion; and,
- a detachable front end cap which alone covers said front end body, said front end cap having a deformable member and an undeformable member,
- wherein said deformable member and said undeformable member are interconnected to form said front end cap.
