PROBLEM TO BE SOLVED: To provide a valve type liquid material exudation tool which lasts long because of no need to frequently carry out a lead push-in operation and causes no blur in a written character or at a liquid-coated part.SOLUTION: A valve type liquid material exudation tool has a liquid material tank shaft 1, a valve storage tube 2 fitted to the liquid material tank shaft 1, and a lead 4 slidably retained in the valve storage tube 2. The valve storage tube 2 is equipped with a liquid material storage member 6 storing a liquid material and a valve unit case 7 with a built-in valve mechanism. The liquid material storage member 6 has a cone shape the apex of which has been removed. A lead insertion hole 8 to slidably store one half part of the lead 4 is formed so as to penetrate through the center, and many slits 9 to store the liquid material are formed radially from the lead insertion hole 8, so that the liquid material stored in the slits 9 can soak into the lead 4 stored in the lead insertion hole 8. |
