16. An electronic device comprising:
a first housing;
a second housing disposed movable with respect to the first housing;
a display disposed on the second housing and slidable into the first housing or sliding out from the first housing by the movement of the second housing;
a motor disposed in the first housing;
a pinion gear disposed in the first housing, and rotatable by receiving driving force from the motor;
a rack gear disposed in the second housing, engaged with the pinion gear, and movable by a rotation of the pinion gear;
a switching structure disposed between at least the motor and the pinion gear, and changeable between a gear-connected state in which the motor and the pinion gear are connected, and a gear-released state in which the motor and the pinion gear are disconnected; and
an actuator connected to the switching structure and configured to change a state of the switching structure,
wherein the switching structure includes:
a first axis to which a driving gear is coupled and rotatable by the motor, one end of the first axis coupled to the motor;
a second axis to which a transmitting gear is coupled, spaced apart from the first axis, and penetrating the pinion gear; and
a cover housing including a first ring gear and a second ring gear spaced apart from the first ring gear along a direction parallel to the first axis, surrounding at least a part of the first axis and the second axis, and coupled to the actuator to be movable by the actuator;
wherein the first ring gear is engaged with the driving gear in the gear-connected state, is spaced apart from the driving gear in the gear-released state,
wherein the second ring gear is engaged with the driving gear in the gear-connected state and the gear-released state.
