First Claim
1. A fastener configured to mount a mounted member on a mount member by being inserted into a holding hole formed in the mounted member and a mounting hole formed in the mount member, comprising:
- a head portion which is disposed on a front side of the mounting hole;
a leg portion which extends from a rear surface of the head portion to be inserted into the holding hole and the mounting hole;
an engaging portion which is provided on the leg portion to be brought into engagement with a rear side of the mounting hole; and
an elastic projecting portion which projects outwards of the leg portion from a predetermined position on the leg portion for elastic deformation,wherein with the leg portion inserted in the holding hole and the engaging portion staying engaged with a rear side of the holding hole, the elastic projecting portion is disposed away from the holding hole,wherein with the leg portion inserted in the holding hole and the mounting hole and the engaging portion staying engaged with the rear side of the mounting hole, the elastic projecting portion is brought into abutment with an inner circumference of the mounting hole to thereby be bent, and a largest outside diameter of a portion of the elastic projecting portion which is positioned on the rear side of the mounting hole is set to be equal to or smaller than a bore diameter of the mounting hole.

Abstract
A fastener to be inserted into a holding hole of a mounted member and a mounting hole of a mount member, includes a head portion disposed on the mounting hole. A leg portion extends from the head portion to be inserted into the holding hole and the mounting hole. An engaging portion is provided on the leg portion to be brought into engagement with the mounting hole. An elastic projecting portion projects outwards of the leg portion. The elastic projecting portion is disposed away from the holding hole. The elastic projecting portion is brought into abutment with an inner circumference of the mounting hole to thereby be bent, and a largest outside diameter of a portion of the elastic projecting portion which is positioned on the rear side of the mounting hole is set to be equal to or smaller than a bore diameter of the mounting hole.

9. A fastener configured to be mounted by being inserted into a mounting hole, comprising:
-
a head portion which is disposed on a front side of the mounting hole; a leg portion which extends from a rear surface of the head portion to be inserted into the mounting hole; an engaging portion which is provided on the leg portion to be brought into engagement with a rear side of the mounting hole; and an elastic projecting portion which projects outwards of the leg portion from a predetermined position on the leg portion for elastic deformation, wherein with the leg portion inserted in the mounting hole and the engaging portion staying engaged with the rear side of the mounting hole, the elastic projecting portion is brought into abutment with an inner circumference of the mounting hole to thereby be bent, and a largest outside diameter of a portion of the elastic projecting portion which is positioned on the rear side of the mounting hole is set to be equal to or smaller than a bore diameter of the mounting hole, wherein the head portion has a fixed flange and a pair of movable flanges, wherein the leg portion has a stem portion extending from a rear surface of the fixed flange and elastic locking pieces respectively extending from rear surfaces of the pair of movable flanges and having the engaging portion, wherein the stem portion has a pair of shaft portions which extend from the rear surface of the fixed flange and the pair of shaft portions are shaped so that the shaft portions extend from positions on the fixed flange which are displaced from a center thereof to be connected to each other at distal end sides thereof, wherein the elastic projecting portion is made up of a pair of elastic projecting portions provided adjacently to the pair of shaft portions, and wherein when the pair of shaft portions and the pair of elastic projecting portions are seen from a direction along an axis of the leg portion, one of the elastic projecting portions projects outwards of the stem portion from a side surface of one of the shaft portions which is at an opposite side to the direction in which the one of the shaft portions is displaced from the center of the fixed flange and is disposed so as to face the other of the shaft portions with the engaging portion left in engagement with the rear side of the mounting hole, while the other of the elastic projecting portions projects outwards of the stem portion from a side surface of the other of the shaft portions which is at an opposite side to the direction in which the other of the shaft portions is displaced from the center of the fixed flange and is disposed so as to face the one of the shaft portions with the engaging portion left in engagement with the rear side of the mounting hole. - View Dependent Claims (10, 11)
