Abstract: A driving device including a stator; a rotor including a rotor frame and provided to be rotatable about a rotational axis of a clothing treatment device through interaction with the stator; and a clutch including a movable member configured to slide along the rotational axis to be selectively coupled to the rotor according to an operation mode of the clothing treatment device. The rotor frame may include a plurality of holes, and a plurality of coupling protrusions protruding toward the clutch so as to be coupled with the movable member when the movable member is slid to be coupled to the rotor. The plurality of coupling protrusions are integrally formed with the rotor frame and punched out of the rotor frame to form the plurality of holes.
