Abstract
A liquid painting instrument according to the present invention includes a neck portion of a cross-sectionally noncircular configuration provided on a wall having a passage hole that allows the neck member of the inner shaft to pass therethrough at a certain position in a circumferential phase while preventing the neck member from passing therethrough at other positions in the circumferential phase. The control wall is located at a position in front of the neck portion in the unknocked state. Projections are also provided on the front face of the neck member; each has a cam face that slides on the rear face of the control wall so as to displace the inner shaft rearward with respect to the fixed position where the valve is closed when the inner shaft is rotated preventing the neck member from passing through the passage hole.
