Abstract

A fastening device includes a case unit including an inner space, a spool received within the inner space and configured for a lace to be wound thereabout, an engaging unit disposed above the spool along an axis, a torque unit disposed above the engaging unit along the axis and including at least one torque portion, and a knob covering the case unit. As a rotation of the knob in a tensioning direction causes the torque unit to drive the engaging unit for allowing the knob to drive the spool, the spool is rotated in the tensioning direction to tension the lace, and as a force born by the at least one torque portion exceeds a threshold, the spool is not rotated in the tensioning direction.
