PROBLEM TO BE SOLVED: To provide a quantitative coating tool which is easy to handle, which can apply a constant quantity of liquid such as a medicine irrespective of a service condition, and which is suitable for deriving a highly viscous liquid.SOLUTION: A quantitative coating tool 1 derives a predetermined quantity of liquid by knocking an operation part (an outer cylinder 2 and a knock rod 3) while an application part 10 being applied to an object to be applied. The operation part or a knock rod 3 constituting a portion of the operation part is moved downward, and a pin 4b of a rotor 4 moves from the upper positions to the lower positions of helical guide grooves 6e and 6d so that the knock rod 3 rotates. Moreover, a screw rod 5 is rotated by the rotation of the knock rod 3, and the screw rod 5 and a piston 12 are moved downward by a screw body 7 so that a liquid of a predetermined quantity is derived from the application part 10. |
