To provide a hole blocking lid body which can suppress the deterioration of a function such as water tightness or the like by setting an insertion force amount small so as to contribute to an improvement of workability or the like, and suppressing the reduction of the withdrawal force amount.SOLUTION: A lid body for blocking a hole of a vehicle body panel comprises a lid main body having a flat plate shape, a columnar wall part having an internal peripheral face and an external peripheral slant face, a bendable connecting bend part for connecting the lid main body and the columnar wall part, and a fillet part for covering an opening peripheral edge of the hole at attachment, and having a groove for positioning the hole. The lid main body has a heavy thickness part in a center region, and a flange part which is formed thin in a thickness at a peripheral edge of the heavy thickness part. The heavy thickness part has a first circular protrusion exposed to the outside, and a second circular protrusion formed at the inside, and a diameter of the first circular protrusion and a diameter of the second circular protrusion are the same with each other, or the diameter of the first circular protrusion is larger than that of the second circular protrusion.SELECTED DRAWING: Figure 3

    【課題】挿入力量を小さく設定し作業性等の向上に寄与すると共に抜去力量の低下を抑えて水密性等の機能低下を抑止し得る穴閉塞用蓋体を提供する。【解決手段】車体パネルの穴を閉塞する蓋体であって、平板形状の蓋本体と、内周面と外周斜面とを有する柱状壁部と、蓋本体と柱状壁部とを連結し屈曲自在な連結屈曲部と、装着時に穴の開口周縁を覆い、穴に対し位置決めする溝を有するヒレ部とを備え、蓋本体は中央領域の厚肉部と、厚肉部の周縁に薄肉に形成したフランジ部とを有し、厚肉部は外側に露呈する第1円形凸部と、内側に配置される第2円形凸部とを有し、第1円形凸部の直径と第2円形凸部の直径は、同径又は第1円形凸部の方が第2円形凸部より大径である。【選択図】図3
