Abstract: A mobile terminal comprises: a case that has an insertion hole formed on a side surface thereof; a metal beam that includes a side metal covering the side surface of the case, and a connection bridge penetrating the insertion hole and extending towards the inside of the case from the side metal; a fixing device that is inserted into a fixing hole formed on the connection bridge so as to be fastened to the case; and a waterproof packing that is interposed between the side surface of the case and the side metal, and that has an opening part through which the connection bridge passes. As a result, water cannot get inside the terminal, and malfunctioning due to water permeation can be prevented thereby.

Abstract: A mobile terminal further comprises: a case having an opening formed therethrough so as to communicate with the inside thereof; and a card tray inserted in the opening, wherein the card tray further comprises a cover part for covering the opening; a support part positioned inside the opening and comprising a seating part on which a card is stably placed; and a flexible part connecting the support part and the cover part and fitted/coupled to the circumference of the opening. The mobile terminal wherein the relative position of the cover part to the support part changes with morphological changing of the flexible part allows the positions of the cover part and the support part in the card tray to be flexibly variable. Therefore, even when positions of the opening and a card socket are mismatched, a card can be mounted in the mobile terminal, thus reducing an initial detective rate and an operationally detective rate.

Abstract: A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, and a lubrication rail. The lubrication rail is made of self-lubricating engineering plastic, and is provided as a pair of lubrication rails. When the first body and the second body move relative to each other, a surface of the lubrication rail significantly reduces friction that occurs in a contact portion between the first body and the second body.
