材（１）を孔（３）とその周辺から取りはずす。Conventionally, as shown in FIG. 8, a plug-like masking material (1) is used, and the masking material (1) is inserted into the hole (3) of the member (2) to apply a surface treatment (4) such as painting. The masking material (1) prevents the surface treatment (4) from reaching the inside of the hole (3). After the surface treatment, the masking material (1) is removed from the holes (3). Alternatively, as shown in FIG. 9, tape (1) A or the like is used,
The tape (1) A is attached to and around the hole (3) of the member (2), and surface treatment (4) such as painting is performed, and the surface treatment (4) is applied to the hole (3) by the tape (1) A. ) And its surroundings. After the surface treatment, the masking material (1) is removed from the hole (3) and its periphery.

ト（５）の取付作業も困難になる。In the prior art shown in FIG. 8, the surface treatment (4) does not reach the inside of the hole (3), but does extend to the peripheral edge of the hole (3). For example, when the hole (3) is a drain hole and the surface treatment (4) is coating, as shown in FIG. 9, the coating (4) rises or is missing at the periphery of the hole (3). It's easy to do. When the masking material (1) is tapered so that it can be applied to holes (3) having different hole diameters to some extent, it becomes overhanging and the paint accumulates, or conversely The surroundings are bad, and the climax (41) and missing of the coating (4) become more prominent,
Further, even when the masking material (1) is removed, the coating (4) around the periphery of the hole (3) may be accompanied by the masking material (1) and peeled off. Therefore, coating (4) on the periphery of the hole (3)
The surface treatment such as is extremely uneven. Normally, a watertight hole (3) is fitted with a tight plug such as a grommet (5) as shown in FIG. 10, but the coating (4) is uneven on the periphery of the hole (3), so the grommet (5) is used. The hermeticity is impaired and problems such as water leakage occur, and the work of attaching the grommet (5) becomes difficult.

孔（３）に固定される。The hole insertion portion (11) A of the masking material (1) A is inserted into the hole (3) to be protected from the surface treatment to cover the hole (3),
At the same time, the peripheral edge (6) A is covered with the hole peripheral edge covering portion (12) A. When the masking material (1) A is attached to the hole (3) and then surface-treated, the hole (3) and its peripheral edge (6) A are protected from the surface treatment by the masking material (1) A. . Since the masking material (1) A is made of a hard thermoplastic foam, it is lightweight and inexpensive, and has an appropriate surface friction coefficient. Therefore, the masking material (1) A can be attached to and detached from the holes (3). When the masking material (1) A is attached to the hole (3), the hole insertion part (11) A of the masking material (1) A is tapered so that its diameter gradually decreases toward the tip. From
Even if the diameter of the hole (3) is smaller than the maximum diameter of the hole insertion part (11) A, the masking material (1) A can be attached to the hole (3) very easily, and the masking material (1) ) When A is attached to the hole (3), the peripheral wall of the hole (3) pushes the periphery of the hole insertion part (11) A of the masking material (1) A to destroy the foam structure of the part. Attachment of the masking material (1) A to the hole (3) is extremely easy due to elastic deformation accompanied by permanent deformation due to the destruction of the foam structure of the masking material (1) A, and the peripheral wall of the hole (3) is a masking material. (1) The masking material (1) A is very firmly fixed to the hole (3) by biting into A and repulsive elasticity based on the elastic deformation.

In addition, the masking material can be easily attached to and removed from the hole, and the masking material can be securely fixed to the hole, and the masking area becomes too large and untreated surfaces can be solved. .

であった場合には水漏れのおそれはなくなる。The present invention will be described with reference to one embodiment shown in FIGS. 1 to 7. The masking material (1) A has a tapered hole insertion portion (11) A whose diameter gradually decreases toward the tip. It comprises a disk-shaped hole peripheral edge covering portion (12) A formed at the root end of the hole inserting portion (11) A. The masking material (1) A is inserted into the hole (3) of the member (2) through the hole insertion portion (11) A, and the hole peripheral edge covering portion (12) A is protected from the surface treatment of the hole (3). Cover the peripheral part (6) A to be treated. When the masking material (1) A is attached to the hole (3) in this way, surface treatment (4) such as painting is performed, but the masking material (1) A is applied to the hole (3) and its peripheral portion (6) A. As a result, the surface treatment (4) is not effected, and therefore the masking material (1) A is removed from the hole (3) after the surface treatment, resulting in the state shown in FIG. Therefore, a grommet (5) is attached to the hole (3) and tightly plugged as shown in FIG. Grommet (5)
Peripheral part (6) of the hole (3) with which the lower surface of the groove (51) comes into contact
Since the surface treatment (4) is not applied to A, the lower surface comes into direct contact with the surface of the member (2) and has a high sealing property. Therefore, when the hole (3) is, for example, a water drain hole in an automobile trunk room. There is no risk of water leakage.

キング材で種々の孔径を有する孔に適用出来る。The masking material (1) A is made of a rigid thermoplastic foam such as polystyrene, polyethylene, polypropylene, or a composite of two or more of the above materials, and the hole insertion portion (11) A is tapered as described above. Therefore, even if the diameter of the hole (3) is set smaller than the maximum diameter of the hole insertion portion (11) A, the workability of inserting the masking material (1) A into the hole (3) is improved. In addition to being improved, it can be applied to holes having various hole diameters with the same size masking material.

上する。Since the hard thermoplastic foam has an appropriate coefficient of surface friction, the masking material (1) A made of this material is very easily attached to and detached from the hole (3), and the masking material (1) A is When it is attached to the hole (3), it is pushed by the peripheral wall of the hole (3) to destroy the foamed structure of that portion of the masking material (1) A, thereby causing elastic deformation accompanied by permanent deformation. The peripheral wall of) bites into the masking material (1) A, and is further firmly fixed by the repulsive elasticity. When the masking material (1) A is colored with a color corresponding to the hole (3) to which the masking material is to be attached, which masking material (1) A
It becomes easy to determine whether or not to install, and workability is improved.

ある。In order to remove the masking material (1) A from the hole (3), it is usually manually removed by using a hook or the like, but the masking material (1) A made of a hard thermoplastic foam is a hook. Is easily pierced, and when heated, it softens and shrinks and can be automatically removed. Such softening / shrinkability is remarkable in the masking material (1) A made of polystyrene foam.

In the figure, a masking material (1) B has a tapered hole insertion part (11) B whose diameter gradually decreases toward the tip, and a corner formed at the root end of the hole insertion part (11) B. The masking material (1) B is composed of a horseshoe-shaped hole peripheral edge covering portion (12) B.
Is the hole (3) of the member (2) as shown in FIG. 2 of the previous embodiment.
The hole peripheral portion (12) B is inserted through the hole insertion portion (11) B and covers the peripheral portion (6) B of the hole (3) which is to be protected from the surface treatment. And the masking material (1)
B protects the inside of the hole (3) and the peripheral portion (6) B from the surface treatment (4) as shown in FIG. The hole (3) is used as a cable insertion hole, and the cable (7) is inserted into the hole (3).
The horseshoe-shaped bracket (8) is attached to the hole (3) by rivets (9) to fix the cable (7) between the peripheral wall of the hole (3) and the bracket (8). The peripheral portion (6) B has a square horseshoe shape corresponding to the bracket (8), and therefore the bracket (8) directly contacts the surface of the member (2), so that the bracket (8) is loosened by the rivet (9). It is firmly attached to the member (2) without the risk of rattling.
