Abstract

The invention provides a hole plug which can cope with thickness change of a component and can restrain sloshing and be stably installed in an opening in a state that the hole plug is temporarily fixed in the opening. The hole plug (10) is provided with a main body part (20), and the main body part (20) is provided with a cover flange part (21) which covers the opening (5); an insertion part (25) inserted into the opening (5); and an engagement part (30) that engages with the back-side peripheral edge of the opening (5). A heat-softening resin member (50) that is affixed to the rear-side peripheral edge of the cover flange section (21) and that is heated and melted to affix the cover flange section (21) to the member (1), the heat-softening resin member (50) having an extension section (60) that extends obliquely outward toward the member (1), and the heat-softening resin member (50) being fixed to the rear-side peripheral edge of the opening (5) in a state in which the engagement section (30) is engaged with the rear-side peripheral edge of the opening (5) and the heat-softening resin member (50) is melted before the heat-softening resin member (50) is melted. The extension section (60) elastically abuts against the surface side of the component (1).

Description

technical field

[0001] The present invention relates to a plug for plugging an opening provided in a predetermined member. Background technique

[0002] Openings used in painting processes, assembly processes, etc. are sometimes formed in members such as body panels of automobiles. Openings like this are typically plugged with plugs.

[0003] As a conventional plug of this type, the following Patent Document 1 describes a plug comprising: a plug main body having a cover flange portion covering the opening of a plate-shaped member; and an annular meltable member disposed on Between the plate-like member and the lid flange is formed of thermosoftening resin, and the meltable member has a structure in which an extension protrudes from a side edge of a portion where a weld line occurs during resin molding. The plug main body is provided with an engaging portion engaged with the back peripheral edge of the opening. In addition, the lid flange portion is in the shape of a long ...

Embodiment Construction

[0037] Hereinafter, one embodiment of the plug of the present invention will be described with reference to the drawings.

[0038] Such as figure 1 As shown, the hole plug 10 is used, for example, to close an opening 5 provided in a predetermined member 1 such as a body panel of an automobile. In the case of this embodiment, the opening 5 has a circular shape, but it may be a rectangular hole, an elliptical or oblong long hole, or the like. In addition, as the member 1, the lid of the cargo compartment of an automobile, a trunk lid, a door, a fender, etc. may be sufficient, and it is not specifically limited.

[0039] And, if figure 2 , Figure 5 As shown, the plug 10 (hereinafter, simply referred to as “plug 10 ”) in this embodiment includes: a main body portion 20 ; and a thermosoftening resin member 50 (hereinafter, simply referred to as “resin member 50 ”).

[0040] First, the main body portion 20 will be described. The main body part 20 in this embodiment has: a co...
