A quarter turn fastener (10) fastens a first component (12) to a second component (14). The fastener (10) has a cap (20) covering and rotating about a cylindrical mounting member (24) with a spring (34) therebetween. The mounting member (24) attaches to the first component (12) by barbs (28). Rotation is limited by a slot and tab arrangement having a tab (42) extending inward from the cap (20) into a slot (44) in the mounting member (24). The slot (44) extends one fourth of the way around the circumference of the mounting member (24) for limiting rotation and includes ridges (46, 48) preventing free rotation of the tab (42) at the ends of the slot (44). A shaft (36) attached to the cap (20) and extends through the mounting member (24), first component (12) and second component (14). A curved retainer member (38) engages slot (18) and has sloping engaging surfaces (52, 54, 56) for guiding the retainer member (38) into and out of the slot (18) when the fastener (10) is twisted. |
