PROBLEM TO BE SOLVED: To prevent the dripping of a coating liquid following the erroneous recognition or the excessive opening of a valve mechanism by setting a part or the whole of a coating liquid occlusion body and a coating body recognizable. SOLUTION: A coating body 1 is inserted into a small diameter section of a through- hole 3 of a front shaft 2 consisting of a small diameter front a section and a large diameter rear section. Ribs 4 are formed on the inner wall of the through-hole 3 of the front shaft 2, and a space between ribs 4 is formed into an air flow opening. A coating liquid occlusion body 5 is disposed on the rear of the coating body 1, and the rear section of the coating body 1 is inserted into the front section of the coating liquid occlusion body 5. The front shaft 2 is molded by using transparent or translucent resin. The rear section 2a of the front shaft 2 is inserted into an engaging step section 2b of a front end opening of a rear shaft 8 and fixed thereon. The coating body 1 inserted from the engaging step section 2b of the front shaft 2 into the front section and the end of the coating liquid occlusion body 5 inserted from the rear opening end of the front shaft 2 are recognizable. The erroneous recognition of the generation of a trouble or the generation of dripping caused by the erroneous operation of excessive valve opening by an user can be prevented by the arrangement. |
