WIPO Patent Application WO/2023/112694

A1

A grommet (20) includes a tubular portion (21). The tubular portion extends along a first direction (DR1) and has a distal end (21a) and a proximal end (21b) opposite to the distal end in the first direction. A through hole (21c) that extends in the first direction and opens at the distal end and the proximal end of the tubular portion is formed in the tubular portion. A first opening edge (21d), which is an opening edge of the through hole at the distal end of the tubular portion when the tubular portion is viewed along the first direction from the distal end side, has a first portion (21da). The first portion includes a first end that is the intersection of the first opening edge and a first straight line (L1) passing through the center (C) of the through hole and along a second direction (DR2) orthogonal to the first direction, and a second end that is the intersection of the first opening edge and a second straight line (L2) passing through the center of the through hole and along a third direction (DR3) orthogonal to the first direction and the second direction.
