To provide a seal structure which attains high sealing performance and enables reduction of attachment work of an attachment component.SOLUTION: A seal member 70 is disposed between a bath room waterproof pan (an object) having an opening 16 and a support lid 30 (an attachment component). The seal member 70 is formed by arranging a main annular part 71, which is wide and thick, and a sub annular part 72, which is narrow and thin, adjacent to each other in a radial direction and connecting the annular parts. The support lid 30 has a support groove 33. A protruding height of a second rib 35 defining an inner periphery of the support groove 33 is low relative to a first rib 34 defining an outer periphery of the support groove 33. The main annular part 71 of the seal member 70 is housed in the support groove 33 and the sub annular part 72 is disposed facing the second rib 35. The seal member 70 is compressed in a state where the support lid 30 is attached to the bath room waterproof pan. Compressibility of the sub annular part 72 is higher than compressibility of the main annular part 71.SELECTED DRAWING: Figure 8
【課題】高いシール性能が得られ、装着部品の装着作業も軽減できるシール構造を提供する。【解決手段】開口部１６を有する浴室用防水パン（対象）と、支持蓋３０（装着部品）との間にシール部材７０が介在されている。シール部材７０は、幅が広く厚い主環状部７１と、幅が狭く薄い副環状部７２とを径方向に隣接して連なることにより構成されている。支持蓋３０は、支持溝３３を有している。支持溝３３の外周を画成する第１リブ３４に対して支持溝３３の内周を画成する第２リブ３５の突出高さは低い。シール部材７０の主環状部７１が支持溝３３に収容され、副環状部７２が第２リブ３５と対向して配置されている。支持蓋３０が浴室用防水パンに装着された状態で、シール部材７０が圧縮される。副環状部７２の圧縮率は主環状部７１の圧縮率より高い。【選択図】図８
