<p><P>PROBLEM TO BE SOLVED: To compatibly attain the improvement in working efficiency when mounting a nozzle, and the improvement in a retaining property of the nozzle in the mounted state, in a structure for mounting the fluid delivery nozzle to a nozzle support hole at the distal end of an insertion section of an endoscope. <P>SOLUTION: In this nozzle mounting structure of the endoscope, the fluid delivery nozzle includes: a head section having a fluid delivery outlet; the tubular insertion section extending from the head section and being inserted in the nozzle support hole; and an external-diameter protrusion section formed at a partial area in the axial direction of the tubular insertion section, protruding from the peripheral face of the tubular insertion section so that its diameter becomes larger than the internal diameter of the nozzle support hole and being inserted in the nozzle support hole along with the tubular insertion section. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
