Claims

[Scope of utility model registration request]

a tip protrusion that has an outer diameter larger than the diameter of a hole formed in the plate and that is to be closed, passes through the hole and protrudes to the opposite side, and locks onto the plate from the back side; a proximal lid portion having a large outer diameter and covering the hole from the opposite side of the distal end protrusion; and a connecting portion having a smaller diameter than the hole diameter and connecting the distal end protruding portion and the proximal lid portion. In this grommet, the distal protrusion, the connecting part, and the proximal lid are coaxially and integrally formed of a soft material, and the distal protrusion has a tapered shape at the distal end, and a center It is formed of a shaft portion and a plurality of axially long fins extending substantially radially from the central shaft portion, and a portion of the tip of the tip protrusion is formed on the end surface of the base end lid portion. A grommet characterized by forming a recess that can be coaxially fitted.
