A laundry machine of the present invention comprises a main body that has a port access hole; a lid that opens and closes the port access hole; and a hinge part that supports the lid, to be able to rotate, against the main body. The hinge part comprises a hinge housing filled with fluid with predetermined viscosity; an elasticity member that is located within the hinge housing; and a pair of cams that has contact surfaces which have different heights along the circumferential direction. When a cam among the pair of cams rotates along with the lid, the contact surface of one cam slides along the contact surface of the other cam so that a distance between the pair of cams is varied and, as a result, the elasticity member is altered, and the contact surface of at least one cam among the pair of cams is formed respectively on at least three sections that are divided by a certain rotation angle along the circumferential direction. |
