A winch is provided for mounting to a wheel of an automobile, including spaced and opposite first and second disks connected by an axle, a cable having a distal end forming a hook, and two nut members. The first disk forms two through holes at opposite locations and each through hole is constituted by a small-diameter outer hole section and a large-diameter inner hole section to form a circumferential internal shoulder therebetween, serving to support a nut member received in the through hole. The second disk forms two bores corresponding to the through holes for the extension of a tool for tightening the nut member. The axle has an outer circumference forming a notch to which a proximal end of the cable is received and fixed. The first disk is secured to the wheel by the nut members received in the through holes and engaging wheel studs. The hook of the cable can be releasably attached to a fixed object so that by operating an engine of the automobile to rotate the wheel, the axle winds the cable thereon to induce a driving force to the automobile by the cable thereby freeing the automobile from for example trapping mud.
