ABSTRACT:
A fastener is provided for securing a first panel-like member to a second panel-like member by securing, in a state with a fastener temporarily secured to the first panel-like member, an elastic fastening portion of the fastener projecting from the first panel-like member toward the second panel-like member. It includes a first flanged portion having long and short sides, a second flanged portion having long and short sides, projecting from the center of the first flange and spaced apart from the first flange by means of a distance corresponding to the thickness of the first panel-like member, an elastic fastening portion projecting from the top of the second flange, and an elastic portion projecting from the second flange toward the first flange and engaged within a hole of the first panel-like member. The long side of the first flange is longer than the long side of the second flange. The short side of the first flange is longer than the short side of the second flange. The first and second flanges are disposed so that the respective long sides traverse each other substantially at right angles. The second flange is inserted within the hole of the first panel-like member and turned by means of a predetermined angle, thus clamping the first panel-like member between the first and second flanges.
