A liquid applicator according to the present invention includes an inner shaft as a liquid reservoir, an applying member, and a valve, wherein near the front end of the inner shaft there is provided a head portion which is non-circular in cross-section along the direction perpendicular to the axial line. At a position in front of the head portion of the inner shaft in an unknocked state, there is provided a controlling wall through which has been bored a through hole which is so designed that the head portion of the inner shaft can pass through the hole when it advances thereby keeping a position in a certain phase of the circumferential direction, while it cannot pass through that hole when keeping a position in another phase.
