PROBLEM TO BE SOLVED: To provide a fastener capable of preventing refuse and moisture from entering, raising an extraction force for a pin, and reducing insertion resistance in inserting the pin. SOLUTION: Since a base 26 of a grommet 16 is formed in a bag shape, refuse and moisture do not enter into the base 26. Accordingly, a water content does not ooze from the base 26 to a floor carpet 14 through an insertion hole 22 of the grommet 16. Also, a through hole 24 is formed in a flange 20 along a direction crossingly perpendicular to the axial direction of the grommet 16, and the flange 20 is divided into an upper part 20A and a lower part 20B. Accordingly, a locking claw 38 or a locking claw 40 can be locked to the upper part 20A. Since the upper part 20A of the flange 20 is recessed along a direction perpendicularly crossing the axial direction of the grommet 16, an extraction force can be increased more than in the case that the upper part 20A is formed in a tilted state relative to the axial direction of the grommet 16 despite the fact that the insertion resistance for the pin 18 is approximately the same.
