1. An electronic device comprising:
a main body having a storage space therein;
a door configured to open and close the storage space; and
a hinge coupled to the door and the main body in order to rotate the door with respect to the main body,
wherein the hinge comprises:
a first bracket supported by the main body;
a second bracket supported by the door;
a link rotatably coupled between the first bracket and the second bracket; a resilient member provided on the link and having an elasticity;
a cam provided on the second bracket and formed in a shape to contact the resilient member, so that according to a rotation direction of the door, the elasticity of the resilient member acts as an opening force or a closing force of the door; and
a cam stopper integrally formed with the second bracket to prevent the cam from being moved by the elasticity of the resilient member,
wherein the cam comprises a triangular column and is anchored to the second bracket by a single through-hole.
