PROBLEM TO BE SOLVED: To provide a fixed quantity feeding device which can apply a constant amount of a liquid without reversing or tilting a container in the fixed quantity feeding device for leading a constant amount of contents by pressing an application body against an object for the application.SOLUTION: A fixed quantity feeding device 1 includes: a tip shaft 3 provided at a front end part of a shaft cylindrical body 2; an application body 4 which moves forward and backward relative to the tip shaft 3 and where a discharge opening for discharging contents is formed at a tip end; a discharge mechanism part 9, 10 which moves a piston 10 to a rear end part side of the shaft cylindrical body and discharges a constant amount of the contents; and a pressing motion transmitting part 6, 7, 8 by which the application body 4 transmits a pressing motion to the discharge mechanism part. While the application body 4 projects from the tip shaft 3, the pressing motion of the application body 4 is allowed. When the application body 4 is housed inside the tip shaft 3, the pressing operation of the application body 4 is prohibited, the pressing motion transmitting part does not operate, and the discharge mechanism part 9, 10 does not operate.SELECTED DRAWING: Figure 1 |
