Eyelet

Abstract

Provided is an eyelet in which a mounting strength to a material is equal to or higher than that in a two-piece type using a washer, and which can Solve a problem of an eyelet coming off of a mounting hole of the material due to material cutting or expansion and contraction of the material during swaging or in use. By holing the material between the tip of each of claws which have been cut and raised from a flange toward the material and the inner surface of a flange-backing portion, a mounting strength of the eyelet can be acquired without concentrating a material-pressing force at one place; the end of the flange-backing portion can be prevented from acting as a cutting edge to cut the material; and an additional position to hold the material is provided, which is different from the holding position by between the end of the flange-backing portion and the end of the flange.

1 . An eyelet to be mounted to a mounting hole which has been formed in a material comprising:
 a flange which is to be placed around the mounting hole; and   a flange-backing portion integral with the flange, which is to be placed around the mounting hole at a position opposite to the flange to hold a part of the material around the mounting hole against the flange;   wherein the flange has a plurality of claws arranged in the circumferential direction with a given space therebetween, the claws being cut and raised toward an inner surface of the flange-backing portion, each of the claws having one or more tips facing the inner surface of the flange-backing portion,   wherein the flange-backing portion and the flange hold the part of the material therebetween, and the tips and the inner surface of the flange-backing portion hold the part of the material therebetween.   
     
     
         2 . The eyelet according to  claim 1 , wherein the one or more tips of each of the claws can pierce the material and press and contact the inner surface of the flange-backing portion. 
     
     
         3 . The eyelet according to  claim 1 , wherein the one or more tips of each of the claws can press the inner surface of the flange-backing portion via the material without piercing the material. 
     
     
         4 . The eyelet according to any one of  claims 1  to  3 , wherein the claws are formed so that the tips point radially outward in the flange. 
     
     
         5 . The eyelet according to any one of  claims 1  to  3 , wherein the claws are formed so that the tips point radially inward in the flange. 
     
     
         6 . The eyelet according to any one of  claims 1  to  3 , wherein the tips of the claws are made sharp.
