Abstract
A fastening device for attaching a heat sink to a heat producer, which is supported on a board having through-holes aligned with mounting holes of the heat sink. The fastening device includes a tube adjacent to one mounting hole, a fastening member movably received in the tube, and an elastic member fitted around the fastening member. The fastening member has an enlarged resilient head, a shoulder and a neck extending between the head and the shoulder, with the head adapted to squeeze through the mounting hole and the through-hole for engaging with a side of the board opposite to the tube. The elastic member includes a minimum diameter section fitted around the heck and abutting the shoulder of the cylinder, a maximum diameter section abutting a distal end of the tube, and an intermediate diameter section stretchable between the minimum and maximum diameter sections.
