である。Conventionally, as this type of masking material (3), a plastic foam material is used, and as shown in FIG. 11, it comprises a hole insertion part (3) A and a flange part (3) B. )
As A, a taper shape whose diameter gradually decreases upward is used. The masking material (3) is, for example,
As shown in FIG. 12, when painting the lower surface of a member such as a floor panel (1) of an automobile body, the floor panel (1) is inserted into a drain hole and a hole (2) such as a screw for attaching a component. Make sure that the inside of the hole (2) is not coated. In addition,
The taper shape of the hole insertion portion (3) A of the masking material (3) is adapted to accommodate holes having various diameters.

The periphery of is covered with the collar (13) B. At this time, as shown in FIG. 3, the masking material (13) has a solid rib (14) formed around the hole insertion portion (13) A and a peripheral wall (12) A of the hole (12).
Is crushed from the dotted line state to the solid line state by the result, the peripheral wall (12) A of the hole (12) bites into the solid rib (14),
The impact resilience due to the crushing of the solid ribs (14) is also synergistic,
It is tightly and firmly fixed to the hole (12) and is prevented from falling off from the hole (12). In this way, the hole (12) and its surroundings are protected by the masking material (13), and then the surface treatment such as painting is applied to the lower surface of the floor panel (11). For example, in the case of painting, the coating film (15) is applied to the lower surface of the floor panel (11), but the coating film (15) is provided inside and around the hole (12) for the masking material (13). ) Is not formed. After the surface treatment, the masking material (13) is removed using a hand key or the like, and, for example, when the surface treatment is painting, the masking material (13) is softened and shrunk by utilizing the heat of the coating baking process. As shown in FIG. 4, the masking material (13) is detached without being fused to the hole (12) and its surroundings.
