ABSTRACT:
To provide a fluid feeder of an applicator having a structure that allows a fluid to flow into a tubular member and be positively pressurized at the time of an ejecting operation, which can readily eject the fluid even if the fluid becomes unlikely to flow out and which allows the user to readily use over a long period of time even if a high-viscosity fluid is used. In the fluid feeder of an applicator, at the time of the closed state, the periphery of a base of a rod-like part comes into hermetic contact with the inner peripheral surface of a fore part of a tubular member. When the thrust against pressing end is weakened after an open state and then the fluid is pressurized before returning to the closed state, the plunger-like part is inserted into the cylinder surface so as to pressurize the fluid held in the space between the inner surface of tubular member and the outer surface on the front side of a step of a valve member, whereby the fluid is flowed out from an ejection opening that is in a state where the periphery of base of valve member is released from the inner peripheral surface of fore part of tubular member.
