An electronic device comprising a first body and a second body, the first body comprising a first printed circuit board, PCB, and the second body comprising a second printed circuit board, PCB,, wherein the second body is movable between a first position at which the second body at least partially overlaps the first body, a second position at which the second body is configured to slide from the first body, and a third position at which the second body is configured to rotate with respect to the first body, the electronic device comprising: a slide member disposed between the first and second bodies (1, 2), the slide member being rotatably coupled to the first body and slidably coupled to the second body; a flexible connection member to electrically connect the first and second PCBs (81, 82); a first opening formed in an upper surface of the first body, the flexible connection member extending through the first opening; a second opening formed in a lower surface of the second body, the flexible connection member extending through the second opening, the upper surface of the first body and the lower surface of the second body being adjacent to and facing each other when the second body is disposed at the first position, and the first opening and the second opening being disposed at opposite sides of the upper surface and lower surface, respectively, when the second body is disposed at the first position; an exposure prevention member coupled to the slide member and configured to prevent the flexible connection member from being externally exposed when the second body is rotated with respect to the first body a rotation shaft about which the second body is configured to rotate to the third position; a protection member configured to prevent interference between the rotation shaft and the flexible connection member, wherein the protection member is disposed between the exposure prevention member and the rotation shaft to form together with the exposure prevention member a space through which the flexible connection member passes, wherein the protection member is configured to prevent the flexible connection member from interfering with the rotation shaft when the second body is disposed at the first position, the second position, and the third position. a slide member disposed between the first and second bodies (1, 2), the slide member being rotatably coupled to the first body and slidably coupled to the second body; a flexible connection member to electrically connect the first and second PCBs (81, 82); a first opening formed in an upper surface of the first body, the flexible connection member extending through the first opening; a second opening formed in a lower surface of the second body, the flexible connection member extending through the second opening, the upper surface of the first body and the lower surface of the second body being adjacent to and facing each other when the second body is disposed at the first position, and the first opening and the second opening being disposed at opposite sides of the upper surface and lower surface, respectively, when the second body is disposed at the first position; an exposure prevention member coupled to the slide member and configured to prevent the flexible connection member from being externally exposed when the second body is rotated with respect to the first body a rotation shaft about which the second body is configured to rotate to the third position; a protection member configured to prevent interference between the rotation shaft and the flexible connection member, wherein the protection member is disposed between the exposure prevention member and the rotation shaft to form together with the exposure prevention member a space through which the flexible connection member passes, wherein the protection member is configured to prevent the flexible connection member from interfering with the rotation shaft when the second body is disposed at the first position, the second position, and the third position.
