Zusammenfassung:	Provided is an electronic device. The electronic device comprises: a housing including a first housing and a second housing which accommodates at least part of the first housing and moves relative to the first housing; a display which is unfolded on the basis of the sliding movement of the first housing; a motor structure which is arranged in the housing and generates a driving force for sliding movement of the first housing; a pinion gear which is rotated on the basis of the driving force generated by the motor structure; and a rack gear which is arranged in the housing, and is to be engaged with the pinion gear. The rack gear comprises: a first portion including at least one recess, the first portion being formed of a first material; and a second portion including a lower region disposed under the first portion and at least partially accommodated in the at least one recess.
