PROBLEM TO BE SOLVED: To reduce a rugged feeling in coating and to ensure the fail-proof opening of a valve even with a small load so as to smoothly discharge a coating agent by projecting a deflection displaceable projecting piece part in the direction of coating application tip in front of a valve part and providing the front end of the projecting piece part 4a with a broad part larger than the thickness size of the projecting piece part. SOLUTION: A valve member 4 having a valve function and a spring-like function is disposed in the through-hole of a coating tip 3. The front end of the valve member 4 is provided with the deflection displaceable projecting piece part 4a. The projecting piece part 4a is formed to a planar shape having a square shape in cross-sectional shape and projects into the coating application part 3b through the aperture 3f of the coating application tip 3. The projecting piece part 4a is provided with the projecting parts 4b projecting so as to flare on the rear side at two right and left points of the forward flank. The rear end of the projecting piece part 4a is successively provided with the valve part 4d of a spherical shape and is provided with two spiral spring parts 4e behind the valve part 4d successively therewith. The collar part of a tip body 5 mounted at the front end of the projecting piece part 4a is formed larger than the thickness size of the projecting piece part 4a and is formed as the broad part. |
