Document Type and Number:
WIPO Patent Application WO/2020/059392
Kind Code:
A1
Abstract:
A grommet 10 has an inner lip 17 and an outer lip 16 having an annular shape and protruding from a facing surface 12b toward an attachment surface 90a so as to provide a seal between the facing surface 12b and the attachment surface 90a over the entire circumference. A first angle α1 formed by the inner circumferential surface 16a of the outer lip 16 and the attachment surface 90a is an acute angle and a second angle α2 formed by the outer circumferential surface 16b of the outer lip 16 and the attachment surface 90a is larger than the first angle α1. Moreover, a third angle α3 formed by the inner circumferential surface 17a of the inner lip 17 and the attachment surface 90a is an acute angle and a fourth angle α4 formed by the outer circumferential surface 17b of the inner lip 17 and the attachment surface 90a is larger than the third angle α3.
