<P>PROBLEM TO BE SOLVED: To make a small-sized stopper member installed in a trigger type liquid injector capable of moving up or down a stopper member through a turning of a nozzle cap fitted to an outer surface of a fitting cylinder formed by a front end part of an injector cylinder and facilitate its moving-up or moving-down motion. <P>SOLUTION: A stopper member 10 is formed in such a way that a first engaging plate 12 is protruded rearwardly from the lower end of a sliding vertical plate 11, an engaging protrusion 12a is arranged at a lower surface of a rear section of the first engaging plate. The lower surface of an injector cylinder 3 and the upper surface of a cylinder 6 are connected by a reinforcing plate 3a. The front surface of the reinforcing plate is set in parallel with the sliding vertical plate 11, positioned at the same location as that the front end of the cylinder or in front of it, the rear surface is contacted with the front surface of the reinforcing plate to enable the first engaging plate 12 to be moved up and down. <P>COPYRIGHT: (C)2003,JPO |
