<P>PROBLEM TO BE SOLVED: To facilitate the attachment/detachment of a stopper without greatly protruding a knob part from a tubular part for locking, in terms of the stopper for preventing the descent of a nozzle, which is to be used for the ejection pump of an article distributed/sold in a state wherein the nozzle is kept in an upper limit position. <P>SOLUTION: This stopper 2 for preventing the descent of the nozzle is formed in such a manner that ribs 2b are paired in the almost opposed positions of the tubular part 2a in the vicinity of the maximum outside diameter part of the tubular part 2a, parallel to a virtual surface F for connecting edges of a notched part 2c which makes the tubular part 2a discontinuous in a circumferential direction. The rib 2b is elongated in the axial direction of the tubular part 2a by being slightly protruded from the outer surface of the tubular part 2a, with respect to the elastically deformable tubular part 2a with an almost C-shaped cross section. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
