る。そこで、本考案はかかる問題点を解消するた
めになされたもので、塗型試験片を通気度試験装
置に設置した時、塗型剤にヒビや割れが発生しに
くい塗型試験片を提供するものである。(Problem to be solved by the invention) When installing a conventional painted test piece in an air permeability test device, as shown in FIG. 12, compressive stress is applied to the test pieces 11 and 12, which causes cracks and cracks in the coating agent 12. Therefore, the present invention was devised to solve such problems, and provides a coating mold test piece that is less likely to cause cracks or cracks in the coating agent when the coating mold test piece is installed in an air permeability testing device. It is something.
（課題を解決するための手段）
本考案は、筒状体の一側開口端に金網を設け、
金網に塗型剤を塗布せしめた塗型試験片である。(Means for solving the problem) The present invention provides a wire mesh at one open end of a cylindrical body,
This is a coated test piece made by coating a wire mesh with a coating agent.
（作用）
塗型の通気度試験に際して、筒状体の他側端部
を通気度試験装置に装着するため金網に応力が加
わらず、塗型剤にヒビや割れが発生しない。(Function) When testing the air permeability of the coating mold, the other end of the cylindrical body is attached to the air permeability testing device, so no stress is applied to the wire mesh, and no cracks or cracks occur in the coating agent.
（実施例）
第１図は本考案に係る塗型試験片であり、筒状
体１の一側開口端に金網２が設けられ、金網２は
粘着テープ又は接着剤等の固定手段３によつて筒
状体１に固着されている。金網２は400メツシユ
