<p>The present invention provides a simple method of manufacturing an insertion portion of an endoscope. The method includes preparing a first bending part (36) which includes a first tubular portion (38) which is elastic and is substantially tube-shaped, and a discontinuous portion which extends across the first tubular portion (38) which extends in a peripheral direction, preparing a second bending part (36) which includes a second tubular portion (38) which is substantially tube-shaped, changing a diameter of the first tubular portion (38) by deforming the first tubular portion (38) elastically, aligning a projecting portion (42) provided with one of the first and second bending parts (36) and extending in a radial direction of the tubular portion (38) with a receiving portion (46) provided with the other of the first and second bending parts (36) by moving the first and second bending parts (36) relatively, and connecting the first and second bending parts (36) swingably relative to each other by releasing the elastic deformation of the first tubular portion (38) to return the diameter thereof to its original state and inserting the projecting portion (42) into the receiving portion (46) rotatably.</p> |
