1. A flexible display device case that is mountable to a flexible display device including a first body and a second body configured to be movable relative to the first body, the flexible display device case comprising:
a first member mountable to the first body to surround a side surface portion of the first body, the first member comprising a first guide portion, wherein the first guide portion surrounds an upper side and a lower side of the first body, and a first slit formed along a first direction perpendicular to a direction in which the first body and the second body move relative to each other; and
a second member mountable to the second body to surround a side surface portion of the second body, the second member comprising a second guide portion, wherein the second guide surrounds an upper side and a lower side of the second body, and a second slit formed along the first direction,
wherein an area overlapped by the first member and the second member changes as the first body and the second body move relative to each other,
wherein the flexible display device further includes a flexible display,
wherein the first member and the second member further comprise an engaging member configured to be rotatable in one direction, and having an engaging surface,
wherein the engaging surface of the engaging member is inserted into the first slit when the flexible display device is such that the first body and the second body are moved closer to each other,
wherein the engaging surface of the engaging member is inserted into the first slit and the second slit when the flexible display device is such that the first body and the second body are moved away from each other such that an area of the flexible display that is exposed to a front surface of the first body is largest, so as to prevent the first plate and the second plate from being moved away from or closer to each other by an external force,
wherein the first member and the second member are configured such that:
the area overlapped by the first member and the second member is largest when the flexible display device is in a first state, in which the first body and the second body are located adjacent to each other such that an area of the flexible display that is exposed to a rear surface of the second body is largest; and
the area overlapped by the first member and the second member is narrowed while the flexible display device is changed from the first state to a second state, in which the first body and the second body are moved away from each other such that an area of the flexible display that is exposed to the front surface of the first body is largest,
wherein the first member and the second member further comprise a shock reducing portion,
wherein the shock reducing portion comprises:
a first plate formed to the first member; and
a second plate including a portion that overlaps the first plate formed to the second member, and
wherein the first plate and the second plate are configured to be capable of being:
disposed adjacent to each other when the flexible display device is in the first state so that the second slit is covered by the first plate; and
moved away from each other when the flexible display device is in the second state so that the first slit and the second slit communicate with each other.
