Electronic device comprising drive motor

An electronic device comprising:

• a first housing including a first space formed through a first lateral member and a first printed circuit board disposed in the first space;
• a second housing slidably coupled to the first housing and including a second printed circuit board disposed in a second space formed through a second lateral member;
• a rear surface cover disposed on an outer surface of the first lateral member;
• at least one electronic component disposed between the first lateral member and the rear surface cover;
• a rollable display that is disposed to be supported by the first housing and the second housing and of which a display area is expanded in the case of transitioning from a slide-in state where at least a portion of the second housing is accommodated in the first space to a slide-out state where the second housing is moving in a first direction, wherein the first direction is a direction in which the display area of the rollable display is expanded;
• a driving motor disposed in the second space, connected electrically to the at least one electronic component and including a pinion gear;
• and
• a rack gear disposed in the first space and gear-coupled with the pinion gear,
• wherein the at least one electronic component is connected electrically to the second printed circuit board through an expandable flexible printed circuit board that is extended into the second space from the first printed circuit board.

An electronic device comprising:

• a first housing including a first space in which a first extension member is disposed;
• a second housing slidably coupled to the first housing and including a second space;
• a support bracket disposed in the first space;
• a rollable display that is disposed to be supported by the first housing and the second housing and of which a display area is expanded in the case of transitioning from a slide-in state where at least a portion of the second housing is accommodated in the first space to a slide-out state where the second housing is moving in a first direction, wherein the first direction is a direction in which the display area of the rollable display is expanded;
• at least one electronic component disposed in the second space;
• a driving motor disposed in the second space, connected electrically to at least one electronic component and including a pinion gear;
• and
• a rack gear disposed on the first space and gear-coupled with the pinion gear,
• wherein the support bracket includes a support part of which an outer surface is formed in a curve to support at least a portion of a support member and a support plate extending from the support part toward the second housing, wherein the support plate is formed to support at least a portion of the support member in the slide-out state.
