PROBLEM TO BE SOLVED: To obtain the fastener that the shaft part is easily inserted and the extraction force is big. SOLUTION: When the extraction force (arrow direction A) acts on a pin 16, the extraction force (arrow direction B) is transmitted to the engagement piece 46 through a slope face 24A of an engagement recessed part 24 and a leg 44 rotates with the support of a root part 44A of the leg 44 and an overhung part 42 presses an external wall 20A of the pin 16 through an engagement part 48 (arrow direction C). Hereby, an overhung part 42 receives the reaction force (arrow direction D) from the pin 16 and the leg 44 rotates with the support of the root part 44A of the leg 44 through the engagement part 48 by this reaction force which is converted to the press force (arrow direction E) where the engagement piece 46 presses the slope face 24A of the engagement recessed part 24. Hereby, the extraction force of the pin 16 is prevented and the clip 12 that is difficult to come off is obtained although the pin 16 is easily inserted. Also, the plastic deformation of the engagement piece 46 is prevented by the extraction force of the pin 16 transferred to other parts through the engagement piece 46 so that a backlash is not arising between a body panel 14 and a decoration member 10.
