A washing machine having a rotor (40) directly connected to a rotary shaft (20). The driving motor (30) includes a stator (31) mounted to an outer surface of a water tub (11), and a rotor (40) disposed around the stator (31) while being directly connected to the rotary shaft (20), which is connected to a rotary tub (12). An insertion hole (44) is formed at a center of the rotor (40), and a plurality of fitting holes (47) are formed around the insertion hole (44). At an end of the rotary shaft (20) is formed an inserting protrusion (21), which corresponds to the insertion hole (44). The rotor (40) is fixed to the rotary shaft (20) by inserting the inserting protrusion (21) through the insertion hole (44). To the rotor (40) is attached a reinforcing member (50) having a plurality of fitting protrusions (52), which vertically extend such that the fitting protrusions (47) are fitted into the fitting holes (47) of the rotor (40), respectively, such that the strength of the rotor (40) is increased.
