A track device includes a first track, a second track slidably received in the first track, and a slide-aiding member mounted between the first track and the second track. A retaining member is securely mounted on a front end of the first track and includes a resilient hook rod. When the second track is removed from the first track, the resilient hook rod of the retaining member is engaged with an engaging notch in a front end of the slide-aiding member, thereby retaining the slide-aiding member in place. When the second track is reinserted into the slide-aiding member and the first track, an unlatching member on the second track urges the resilient hook rod of the retaining member to disengage from the engaging notch of the slide-aiding member, allowing further inward sliding movement of the second track into the first track.
