An objective of the present invention is to reduce or interrupt delivery of sounds and vibration and improve sound shielding efficiency by an air layer in a space formed inside a hole plug that closes an opening of a panel, such as a vehicle body. The hole plug (200) includes an annular first flange part (220) that is in contact with the circumferential periphery (for example, an upper circumferential periphery) of one side of an opening (211) formed in a panel (210), a first cover part (230) that closes the opening (211) together with the first flange part (220), and a closing part (240) that includes a specific space (250) between the first flange part (220) and the first cover part (230) to close the opening (211) as the first cover part (230) is caught by the circumferential periphery (for example, a lower circumferential periphery) of an opposite side of the opening (211).

    (과제) 차체 등의 패널의 개구를 폐색하는 홀 플러그에 관해서, 내부에 공간을 형성함으로써 이 공간 내의 공기층에 의해서 소리 및 진동의 전달을 저감 내지는 차단하고, 차음성을 향상시키는 것을 과제로 한다. (해결 수단) 홀 플러그(200)는, 패널(210)에 형성된 개구(211)의 일방측 둘레가장자리(예를 들면 상측 둘레가장자리)에 맞닿는 환형상의 제 1 플랜지부(220)와, 제 1 플랜지부(220)와 함께 개구(211)를 폐색하는 제 1 덮개부(230)와, 개구(211)의 타방측 둘레가장자리(예를 들면 하측 둘레가장자리)에 걸어맞춤으로써, 제 1 플랜지부(220) 또는 제 1 덮개부(230)와의 사이에서 소정의 공간(250)을 구비하여 개구(211)를 폐색하는 폐색부(240)를 구비한다.
