(How to install hole plug 10) Next, a mounting method for closing the through hole 21 of the body member 20 as shown in FIGS. 17 to 21 using the hole plug 10 having the above configuration will be described.
- the meltable member 40 is attached to the entry portion 60 of the plug body 30.
- the center hole 41 of the meltable member 40 is fitted in accordance with the protrusion 60 of the plug body 30.
- the inner diameter of the central hole 41 is formed to be slightly smaller than the outer diameter of the protruding part 60, so that the protruding part 60 fits while expanding the opening edge of the central hole 41.
- the meltable member 40 gets over the hook 64 and can be prevented from falling off by the hook 64.
- the meltable member 40 is inserted deeply to the lower side of the flange portion 50 of the plug main body 30, that is, to a position where it abuts on the flange portion 50.
- the opening restoring portion of the center hole 41 is brought into close contact with the outer peripheral surface of the entry portion 60 due to the compressive restoring force of the meltable member 40 and cannot be detached from the entry portion 60.
- the entry portion 60 of the plug body 30 is inserted in accordance with the through hole 21 of the body member 20.
- the hook 64 that protrudes from the outer peripheral surface engages with the opening edge of the through hole 21.
- the hanging portion 64 is pushed by the opening edge portion of the through hole 21, and the portion of the thin portion 66 is bent, so that the intrusion portion 60 is reduced in diameter, The hanging portion 64 can pass through the through hole 21.
- the rib 65 is pushed against the opening edge of the through hole 21 and bent as shown in FIG. 26, so that it is between the body member 20, that is, the outer peripheral surface of the entry portion 60 and the through hole 21.
- a gap 70 is generated between the inner edge and the inner edge.
- the hook portion 64 When the hook portion 64 passes through the through hole 21, as shown in FIG. 23, the hook portion 64 protrudes due to the elastic restoring force of the plug body 30, and is hooked on the back surface of the body member 20, that is, the lower surface in FIG. Cannot be removed from the through hole 21. At this time, the flange portion 50 elastically contacts the surface of the body member 20, that is, the upper surface in FIG.
- the body member 20 is elastically sandwiched between the flange portion 50 and the hook portion 64 from the front and back surfaces.
- the vicinity of the through hole 21 of the body member 20 is heated as a whole.
- the meltable member 40 is melted, and a molten resin is formed between the lower surface of the flange portion 50 and the surface of the body member 20, and between the outer periphery of the protrusion 60 and the opening edge of the through hole 21. Flows and then solidifies, thereby sealing between the plug body 30 and the through hole 21 of the body member 20, and fixing the plug body 30 to the body member 20.
- the molten resin flows into the gap 70 (see FIG. 26) generated between the outer peripheral surface of the entry part 60 and the inner edge part of the through hole 21, and closes the gap 70.
- the molten resin flows into the “gap” between the outer peripheral surface of the intrusion part 60 and the inner edge of the through-hole 21 of the meltable member 40, and the “gap” ”.
- the molten resin that has flowed into the gap 70 is then solidified, thereby closely contacting the lower surface of the flange portion 50, the outer peripheral surface of the protruding portion 60, and the surface of the body member 20, and the outer peripheral surface of the protruding portion 60 and the inner edge of the through hole 21
- the plug body 30 is fixed to the body member 20 as well as sealing between the two parts. Furthermore, when the meltable member 40 is melted and softened, the flange portion 50 is elastically restored to the initial shape, so that the molten resin flows out from between the flange portion 50 and the opening edge of the through hole 21 to the outside. It is suitably held without.
- the molten resin is pressed by the restoring force of the flange portion 50, and the space between the flange portion 50 and the opening edge portion of the through hole 21 is suitably filled, so that the gap between the two can be reliably sealed.
- the single heating step of the meltable member 40 can be omitted by simultaneously heating in the heating process at the time of dipping coating drying.
- FIG. 27 A gap 70 can be formed between the opening edge of the center hole 41 and the center hole 41. That is, when the inner diameter of the through hole 21 of the body member 20 is large or the rigidity of the rib 65 is high, the rib 65 maintains the protruding state as shown in FIG. At this time, the opening edge portion of the center hole 41 of the meltable member 40 rides on the rib 65, so that a gap 70 is generated between them. The molten resin melted by the meltable member 40 flows into the generated gap 70 during heating, and the sealing effect can be achieved by closing the gap 70.
- the entire contents of the description, claims, drawings and abstract of Japanese Patent Application No. 2013-012861 filed on Jan. 28, 2013 are incorporated herein as the disclosure of the description of the present invention. Is.
