1. A laundry treating apparatus comprising:
a tub configured to store water therein;
a drum rotatably located in the tub to receive laundry therein;
a pulsator rotatably located in the drum to agitate the laundry;
a driver coupled to the tub, the driver being configured to provide power to rotate at least one of the drum and the pulsator; and
a clutch located between the driver and the pulsator to transmit the power to the at least one of the drum and the pulsator, the clutch including:
a gear assembly rotatably engaged with the driver;
a rotation shaft coupled to the gear assembly to rotate the pulsator;
a housing coupled to the drum to rotate the drum, the housing being configured to receive the gear assembly and the rotation shaft therein; and
a coupler configured to connect and disconnect the driver and the housing to selectively rotate the housing, the coupler being located in the housing,
wherein the driver includes:
a stator coupled to the tub;
a rotor configured to be rotated by the stator; and
a driving shaft coupled to the rotor and the gear assembly, the driving shaft being located in the housing,
wherein the coupler is configured to selectively couple the housing and the driving shaft to each other,
wherein the driving shaft includes:
a shaft body extending from the rotor to the gear assembly; and
a power serration disposed on an outer circumferential surface of the shaft body, the power serration configured to be coupled to the coupler to rotate the coupler, and
wherein the housing includes:
a connection housing receiving the driving shaft therein, the connection housing being configured to allow the coupler to ascend and descend therein; and
a coupling serration located on an inner circumferential surface of the connection housing, the coupling serration configured to be coupled to the coupler to rotate the connection housing.
