A hold-down support structure is coupled to a stem of a pintle to form a hinge, and includes a support board and a sleeve. The support board has a support section forming a support face. The sleeve includes first and second brackets. When the sleeve is mounted to the support board, a stem receiving space is defined by by the support board and the first and second brackets. The stem is inserted into the stem receiving space and an outer circumferential surface of the stem is subject to constraint by the support face of the support board and the resilient retention forces respectively applied by the first and second brackets symmetrically in directions toward the support face so that a predetermined rotational friction is induced between the outer circumferential surface of the stem and the inside surfaces of the first and second brackets.
