Abstract
An outer shaft of an applicator axially slidably receives an inner shaft, which is axially moved through a push-out operation thereof; and the inner shaft is provided a valve unit, an opening/closing operation of which is interlocked with such push-out operation of the inner shaft, which valve unit is connected with an application-liquid intake conduit fixed to an inside of the outer shaft; in a front end portion of the outer shaft is mounted an application-liquid applying member to which is fed the application-liquid such as an ink, a nail polish and like liquids having passed through the valve unit and the application-liquid intake conduit. A clearance is provided between a front end of the valve stem of the valve unit and the rear end of the application-liquid intake conduit, and a spring means is provided between the liquid intake conduit and the outer main shaft to compensate for undesired looseness.
