According to an aspect of the invention, the circumferential position of a protrusion portion of a light guide member is aligned with the position of a second groove portion of a pressing member and a tip portion of the light guide member is inserted into an insertion hole. Next, the light guide member is rotated to align the circumferential position of the protrusion portion of the light guide member with the position of a first groove portion of a mounting hole, and the tip portion of the light guide member is mounted in the mounting hole of a tip portion body. After that, a screw member is inserted into a through hole of the pressing member, is threadedly inserted into a screw hole of the tip portion body, and fixes the pressing member to a base end face of the tip portion body.

Endoscope and method of assembling endoscope

The insertion part of the endoscope has a cap fixed to the distal end face of a distal end body. A projecting part of the cap is inserted in a receiving hole formed on the distal end face. The inserted projecting part is fixed to the distal end body with a screw inserted in an attachment hole, which is formed on the periphery of the distal end body and connects with the receiving hole. Bending rubber covers the attachment hole as well as the outer periphery of the distal end body.

Endoscope

In an endoscope tip part in which a lens barrel is arranged and fixed to a mounting hole of a support body of the endoscope tip part and to this lens barrel, and an optical member such as an optical filter or a prism is connected by an optical part holding fixture, a part of an endoscope outer peripheral side of the optical part holding fixture is cut off, and to this notch part, the mounting hole is extended out like an extending part, and a step part on an outside of this support member is made deep (diameter is reduced). If an end part of an outer skin is bound with a string on this step part with a small diameter and fixed by adhesives, a swell of an outer skin fixing part is eliminated, and an insertion of the endoscope also becomes easy.
