PROBLEM TO BE SOLVED: To provide an assembling structure of a grommet capable of reducing an insertion force and securing a holding force of the grommet and sealability when assembling the grommet with a bracket.SOLUTION: A grommet (10) includes a small-diameter flange part (11) and a large-diameter flange part (12) from one end portion, and an annular lock groove (13) is formed between the small-diameter flange part (11) and the large-diameter flange part. In the assembling structure of the grommet, the lock groove (13) of the grommet (10) is fitted to an edge of a hole (21a) of a bracket (20) including the hole (21a), such that the grommet is locked to the bracket. In the grommet, areas from an end portion to the small-diameter flange part are connected by a conical slope (15) and on the conical slope (15), a plurality of vertical grooves (16) in an axial direction are formed over a full circumference. |
