ABSTRACT:
A fastener includes a female body and male body. By forcibly inserting the male body into a male body insertion hole of the female body, the two bodies are temporarily coupled together. By further inserting the male body into the female body from this state, leg portions of the female body are caused to flare outwardly so that overlapped plates are fastened together between the flared leg portions and a head portion of the female body. By further inserting the male body into the female body from this state, the leg portions are released from the flared state, so that the plates can be unfastened. When and only when the leg portions are inserted through a hole of a plate to be fastened by means of the fastener disposed in the temporarily coupled state, can the male body be further inserted within the female body so as to fasten the two plates to each other.
