PROBLEM TO BE SOLVED: To provide a hole plug for closing an opening of a panel of a vehicle body, which forms a space therein, to reduce or block transmission of sound and vibration with an air layer of the space, thereby improving sound insulation property.SOLUTION: A hole plug 200 includes: an annular first flange part 220 contacting with a one-side peripheral edge (for example, upper peripheral edge) of an opening 211 provided in a panel 210; a first lid part 230 closing the opening together with the first flange part; and a closing part 240 that is engaged to the other-side peripheral edge (for example, lower peripheral edge) of the opening, has a predetermined space 250 between the first flange part and the first lid part, and closes the opening.SELECTED DRAWING: Figure 22

    【課題】車体等のパネルの開口を塞ぐホールプラグに関し、内部に空間を形成することで、当該空間内の空気層により音及び振動の伝達を低減ないしは遮断して、遮音性を向上することを課題とする。【解決手段】ホールプラグ200は、パネル210に設けられた開口211の一方側周縁(例えば上側周縁)に当接する環状の第1フランジ部220と、第1フランジ部と共に開口を閉塞する第1蓋部230と、開口の他方側周縁(例えば下側周縁)に係合し、第1フランジ部または第1蓋部との間で所定の空間250を備えて開口を閉塞する閉塞部240と備える。【選択図】図22
