1. A washing machine comprising:
a housing;
a drum rotatably disposed inside the housing, and including a rotation shaft that extends in a vertical direction;
a driving motor to generate rotational force to rotate the drum;
a driving shaft configured to transfer the generated rotational force from the driving motor to the drum; and
a driving shaft flange configured to connect the driving shaft to the drum,
wherein the driving shaft flange comprises:
a first surface;
a second surface parallel to the first surface, wherein the first surface and the second surface spaced apart from each other by a predetermined distance in the vertical direction; and
a plurality of connection portions formed perpendicular to the first surface and the second surface and connecting the first surface to the second surface,
wherein an outermost end of the first surface, an outermost end of the second surface, and an end of an outermost connection portion of the plurality of connection portions in a circumferential direction of the drum are substantially aligned in an axial direction of the driving shaft, and
the first surface, the second surface, and one connection portion of the plurality of connection portions are in an H-beam form having an ‘H’ shape such that at least a portion of a cross section of the driving shaft flange along an extending direction of the driving shaft is in the ‘H’ shape.
