A masking member.

摘要

A masking member used to protect the inside and circumference of a hole of an article from a surface treatment such as coating. The masking member comprises an inserting part (2) having a vessel shape and a flange (3) extending from the end of said inserting part (2) wherein a cross-rib (21) is formed in the bottom surface of said inserting part (2) for reinforcement and a corrugated surface (31) is formed on the outer surface of said flange part (3) and further, a rim (32) is formed by the upper edge (32) of said flange being folded. The masking member is attached in a hole (5) of an article (4) by inserting said inserting part (2) into said hole (5) and after a surface treatment (6), said masking member (1) is removed by hooking said folded edge of said flange of said masking member (1) with a hook (7) and the like. Said hook may or may not also stick into the side of the flange. When said masking member (1) is removed by using said hook (7) as above described, the deformation of said masking member (1) is suppressed by the rib-effect of said corrugated surface (31) of said flange and said masking member (1) is removed effectively by using said hook (7). <IMAGE>
