Claims

[Scope of utility model registration request]

(1) A tip protrusion having an outer diameter larger than the diameter of a hole to be closed formed in the plate, passing through the hole and protruding to the opposite side, and engaging the plate from the back side; a proximal lid portion having an outer diameter larger than the hole diameter and covering the hole from the opposite side of the distal protrusion; and a proximal end cap portion having an outer diameter smaller than the hole diameter of the hole and connecting the distal protrusion and the proximal lid portion. In the grommet, the distal protrusion, the coupling part, and the proximal lid are coaxially and integrally formed of a soft material, and the distal protrusion has a tapered tip shape. Also, a grommet comprising a central shaft portion and a plurality of axially long fins extending substantially radially from the central shaft portion.

(2) At least one end surface of the distal end protrusion and the proximal end cap facing the gap between the distal end protrusion and the proximal end cap around the connecting portion is arranged in a plane perpendicular to the grommet center axis. On the other hand, the grommet according to claim 1, which is a utility model, has an inclined surface that expands outward.

(3) The fin is provided with an integral hinge in the radial direction of the grommet that allows the radially outer end to be bent radially inward. Grommets listed.

(4) The plurality of fins have a cross section orthogonal to the central axis and are curved in the same rotational direction around the central axis. 3
Grommet as described in section.

(5) A utility model in which the ends of the plurality of fins facing the base end lid are bent in the same rotational direction about the grommet center axis along a plane perpendicular to the grommet center axis. A grommet according to any one of registered claims 1 to 4.

(6) The plurality of fins are spirally twisted in the same rotation direction around the central axis of the grommet, according to any one of claims 1 to 5 of the utility model registration claims. grommet.
