FASTENER
First Claim
1. A fastener which is made of a resin and which is to be attached to attachment holes of attachment members, the fastener comprising:
- a grommet havinga head portion with an opening, andplural leg pieces engageable with an edge of the attachment holes of the attachment members at their outer surfaces by being expanded; and
a pin member which is pushed in through the opening to thereby expand the plural leg pieces,wherein each of the leg pieces has;
a bendable portion which projects downward from the head portion and which is bendable to be expanded;
an inclined surface which is inclined downward as it approaches toward a center axis, and which receives a push-in force from the pin member when the pin member is pushed in; and
a recess formed between the bendable portion and the inclined surface, andwherein the inclined surface is formed so as to be distant from an inner surface of the bendable portion inward in a radial direction through the recess.

Abstract
A fastener attached to an attachment hole of an attachment member, wherein a grommet has a head section having an opening, and a plurality of leg pieces having an outer surface capable of engaging with an edge of the attachment hole of the attachment member by expansion of the leg pieces. A pin member is pressed in from the opening to splay the plurality of leg pieces. The leg pieces each have: a flexure section that extends downward from the head section and is flexible for spreading out; and an inclined surface that is formed radially inwardly away from an inner surface of the flexure section, inclined downwardly toward the center axis, and subjected to a pressing force from the pin member when the pin member is pressed in.
