A hinge assembly is provided to prevent noise of a pair of rollers by rolling the rollers of a rotating unit along the inner wall of a guide hole of an elastic deformable unit. A hinge assembly includes a body unit(100), a deformable unit(200), a rotating unit(300), and a cover unit(400). The body unit has a receiving space(110) inside and forms a body of the hinge assembly. The deformable unit, made of rubber, is received in the space of the body unit and has a non-circular guide hole(210) inside. One end of the rotating unit is coupled with one end of a hinge shaft(13) to be rotated as the hinge shaft rotates, and the other end is inserted into the guide hole of the deformable unit and has a non-circular shape complementary to the shape of the guide hole. The cover unit closes the space of the body unit from the outside and has an exposure hole(410) to expose the other end of the hinge shaft. The guide hole has protrusions(220) to prevent vibration of the rotating unit, and a non-contact section(230) not in contact with the rotating unit. |
