Abstract:
1. A fastener adapted to be attached to a sheet-shaped member, so that the sheet-shaped member can be attached to a mounting member via the fastener, the fastener comprising: a tubular shank adapted to be inserted into a mounting hole of the sheet-shaped member; a plurality of individual holding piece arms, extending radially outward from corresponding partial portions of the periphery of a first end of the shank, and substantially in a same plane as the first end of the shank, the holding piece arms being separated from each other by open spaces in said plane that are substantially greater in width than width of said holding piece arms in said plane; a flange extending outward from a second end of the shank, and having an outer cross-dimension greater than an inner cross-dimension of the mounting hole of the sheet-shaped member; and at least one stud-engagement pawl extending into the interior of the shank, wherein the shank has a length less than that of a stem of a stud fixed to a mounting member with which the fastener is to be engaged, so that the stud stem protrudes from a first surface of the sheet-shaped member after the shank is inserted into the mounting hole, with the holding piece arms leading, until the holding piece arms are adjacent to the first surface and the flange is adjacent to an opposite second surface of the sheet-shaped member, and the stud is passed through the shank and the pawl is engaged with the stud, and wherein protrusion of the stud stem allows an auxiliary member to be mounted thereto.
