Claims

[Scope of utility model registration request]

In a screw grommet, which is composed of a flange part and a body part, and has an insertion hole for the screw means formed from the flange part into the body part, the body part is inserted from the bottom surface of the flange into the inner wall surface of the body part defining the insertion hole. A certain area of the inner wall surface is made to protrude inward, and the diameter of the insertion hole portion defined by the protruding inner wall surface portion is smaller than the diameter of the other insertion hole portions, and the screw means is screwed in. A screw grommet characterized in that it is configured such that only the protruding inner wall surface portion expands outward.
