WIPO Patent Application WO/2016/098559
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve, in a grommet to be fitted into a track-shaped through hole, a water-stopping property between an inner circumferential edge of the through hole and a bottom surface of a ring-shaped groove of the grommet. A grommet of the present invention comprises: a cylindrical part; and a fitting part that is formed so as to protrude to an outer circumferential part of the cylindrical part and that has formed, in an outer circumferential part thereof, a ring-shaped groove into which the inner circumferential edge of the through hole can be inserted. A bottom surface of the ring-shaped groove is formed in a track shape that has a pair of straight-line portions and a pair of arc-shaped portions that are each formed in an outwardly convex arc shape and that connect the two ends on one side of the pair of straight-line portions and the two ends on the other side of the pair of straight-line portions. An inner circumferential part of each arc-shaped portion includes a part having a thickness that gradually increases from the center thereof toward connecting parts between the arc-shaped portions and the straight-line portions.
