A washing machine according to the present invention comprises a hinge device comprising a cam member, a lever, and an elastic member. The cam member has an outer peripheral surface comprising a first section and a second section, which are formed to have different curvatures, respectively, and a third section arranged between the first and second sections. The cam member is profiled such that, when the lever contacts respective sections, the same can be arranged in a first position in which the door is automatically opened, in a second in which the door is automatically closed, and in a third position in which the external resultant force of the cam member becomes zero, thereby controlling the closing rate of the door. The power transfer scheme is simplified using a cam, the material cost can be saved by reducing the number of components, and reliability of the washing machine driving can be secured.
