Abstract
Provided is a laundry treatment machine which may include at least one hinge that supports a lid on a main body. The hinge may include a hinge housing, an elastic member disposed inside the hinge housing, and a pair of cams disposed in the housing to move in linkage with the lid and the elastic member. The cams may include contact surfaces that are inclined relative to each other in an axial direction of the cams, and when a contact surface of one of the cams slides along a contact surface of the other cam, a distance between the pair of cams may be changed to deform the elastic member. The contact surface of at least one of the cams may be divided into at least three sections by a prescribed angular range along the circumferential direction, each of the three sections having a separate contact surface.
