  • Patent number: 9790976
    Abstract: An embodiment provides a fastener including a locking member and a pin member which are connected. The locking member has a pair of leg portions that are inserted into the mount hole and a flange portion that is brought into abutment with a portion of the mount-base member that lies on a circumference of the mount hole. The pin member has a head portion that is connected to the flange portion and an extending portion that extends from a rear side of the head portion. When the head portion of the pin member is forced into the locking member, a connection between the flange portion and the head portion is released, and the extending portion travels between the pair of leg portions to expand open the pair of leg portions or to restrict the pair of leg portions from moving towards each other.
