1. A washing machine comprising:
a tub;
a drum rotatably installable inside the tub; and
a bearing housing to rotatably support a shaft configured to drive the drum while the drum is installed in the tub, the bearing housing comprising:
a stator coupling portion to which a stator of a drive motor configured to rotate the shaft is coupled;
a plurality of leg portions spaced apart from each other along a circumferential direction of the stator coupling portion; and
a connection portion provided to connect between adjacent the plurality of leg portions to each other,
wherein each of the plurality of leg portions comprises:
a leg plate having a first end connected to the stator coupling portion and a second end formed to extend along a radial direction of the stator coupling portion from the first end;
an outer rib spaced apart from the stator coupling portion along the circumferential direction of the stator coupling portion, the outer rib being formed to protrude from the leg plate along an edge of the leg plate; and
a central rib formed to extend from the stator coupling portion to a portion adjacent to the second end,
wherein the connection portion includes a first edge that is further apart from the stator coupling portion than a second edge along the circumferential direction of the stator coupling portion,
wherein the outer rib and the central rib are respectively formed to protrude from the leg plate in an axial direction of the shaft.
