FASTENER

WIPO Patent Application WO/2017/064912

A1

Provided is a fastener having a structure which makes the fastener unremovable after the fastener is affixed and which prevents the rotation of a male body relative to a female body. A male body 10 is provided with an engagement protrusion 14 comprising: a male body shaft section 15; a flange section 16; and a side guide wall 18. A female body 20 has formed therein a shaft hole 25 into which the engagement protrusion 14 of the male body 10 is inserted, and the shaft hole 25 has formed therein a fitting space 27 and an upward facing stepped section 26 which engages with the downward facing stepped section 17 of the male body 10. The female body 20 further has a split groove 28 formed in the portion of the female body 20, which extends from a female body base section 23 through the upward facing stepped section 26 to a part of a female body shaft section 24. When insertion is performed while the side guide wall 18 and the split groove 28 are matched to each other, the downward facing stepped section 17 and the upward facing stepped section 26 engage with each other, and the rotation of the male body 10 is prevented. When insertion is performed while the positions of the side guide wall 18 and the split groove 28 are shifted from each other, the upward facing stepped section 26 comes in pressure contact with the outer peripheral surface 18a of the side guide wall 18, and a temporarily affixed state is obtained.
