Abstract: A fastener includes a fitted portion having an elastic piece that is disposed on a side of a base portion configured to allow insertion of the fitted portion into a through hole by elastic deformation in a direction of approaching a base portion and to engage the through hole at an insertion point of the insertion by elastic return in an end position of the insertion, and that is configured to, if force in a direction of pulling out the fitted portion from the through hole is applied, cause the elastic deformation in the approaching direction. The base portion includes an abutting portion abutting on the elastic piece if the force in the pulling-out direction is applied, and, if the force in the pulling-out direction is equal to or greater than a predetermined magnitude, the elastic piece bends in a direction toward a central axis of the fitted portion.
