Driving structure and electronic device comprising same

An electronic device comprising:

• a first housing;
• a second housing configured to slide relative to the first housing;
• a display including a first display area and a second display area extending from the first display area, wherein at least a portion of the second display area is configured to be moved based on a sliding movement of the second housing;
• and
• a driving structure configured to provide a driving force for sliding of the second housing with respect to the first housing
• wherein the driving structure includes a motor fixed to the first housing, a pinion gear connected to the motor and configured to rotate in one direction or in another direction opposite to the one direction based on a driving force of the motor, a rack fixed to the second housing and including at least a portion configured to be engaged with the pinion gear, and a gear bracket receiving at least a portion of the pinion gear and at least a portion of the rack and fixed to the motor and the first housing,
• wherein the gear bracket includes a first first coupling portion and a second first coupling portion coupled to the first housing, and
• wherein a virtual first straight line connecting the first first coupling portion and the second first coupling portion are parallel to a sliding direction of the second housing.
