PROBLEM TO BE SOLVED: To constitute a main body and a spray nozzle attached thereto detachably so as to drive simply and safely without leakage. SOLUTION: Detachable rapid rotational connection assembly (22, 24, 26, 28, 30) is formed between the spray nozzle (2) and the main body (4) and a terminal part in the rear side of the spray nozzle is formed as a male connection element (19) and an end part in the front of a fluid duct (12) of the main body is formed as a female connection element (18) housing the element (19). The spray nozzle has lock protrusion parts (22, 24) projecting to separate in the horizontal direction from the inserting part, a lock surface (32) facing the rear side is formed in the inserting element, the lock projecting part is turned to the rear side of the lock surface by turning the spray nozzle to a position in the axial direction to which the spray nozzle is completely inserted and as a result the spray nozzle is locked in the axial direction at the position in the axial direction. |
