補正昭６２．９．２８図面の簡単な説明を次のように補正する。明細書の第１０頁第６行目に「押圧力」とある
を「弾性エネルギー」と訂正する。Amendment September 28, 1982 The brief description of the drawing is amended as follows. On page 10, line 6 of the specification, "pressing force" is corrected to "elastic energy."

Claims

[Claims for Utility Model Registration] A plug made of a rubber material that is attached to a burring hole provided in a panel and has a burring flange projecting to one side to close the burring hole, A cylindrical portion to be fitted, a diaphragm-shaped closing portion that closes the cylindrical portion and is flexible and deformable in the axial direction, and a plurality of cylindrical portions formed on one side of the closing portion with gaps in the circumferential direction. a rib; a first flange portion formed at one end of the cylindrical portion and in close contact with one opening surface of the burring hole; and a press displacement in the axial direction of the closing portion formed at the other end of the cylindrical portion. As a result, it is pressed outward through the rib, and when it crosses the neutral point, it is reversed and brought into close contact with the outer peripheral surface of the burring flange from the other opening surface of the burring hole, and prevents the pressing displacement of the closing portion. An elastic plug comprising a second flange portion that maintains an inverted state even when released.
