PROBLEM TO BE SOLVED: To enable the selection of a liquid injection direction by the turning of a nozzle.SOLUTION: When a grip part 21 is gripped by one hand and pulled by putting a forefinger on a finger hook part 22a, the finger hook part 22a is turned with a shaft 22c as a center. A pressure part 22b of the finger hook part 22a allows a shaft part 23n of a piston part 23m to be pushed in, so as to heighten the inner pressure of a liquid filling part 23j. A washing liquid W flows out from the inside of the liquid filling part 23j to an overflow tube 23i via a nonreturn valve 23l. Then, the washing liquid W is injected forward from a nozzle 24. When the washing liquid W is injected from the nozzle 24, the washing liquid W passing through a main injection hole is ejected in a front direction. The washing liquid W passing through a sub-injection hole is linearly ejected to be spread in a horizontal direction toward a wide head 31 attached to a distal end part 23, so as to be injected. The washing liquid W is attached onto a cleaned surface. |
