An apparatus for fastening a shoelace includes a housing, a rotating cover, a reel part, and a restricting member. The housing includes a ratchet gear. The restricting member includes a repulsion restricting part which is provided between the rotating cover and the reel part and includes a ratchet coupling part protruding from an external circumference thereof to restrict a rotation in one direction by the ratchet gear, and a pressure coupling part which is slidably contacted and pressed by a rotation of the restricting projection in the other direction along a rotational radius and is repulsively deformed and selectively coupled to the coupling accommodation part.
