Abstract: A portable device includes: a front case comprising, about an edge of its border, a protruding front case fixing claw, and a recess formed on an inner side of this claw; a battery lid contoured to fit externally to a lower case at its outer border edge; a middle case contoured to fit into the front case and comprising, about an edge of its border, a protruding middle case fixing claw engaging in the recess; and the lower case coupled to the middle case and comprising a hole. Both the claws pass through the hole. The lid urges the front case claw toward the middle case claw while fitting externally to the lower case. With this configuration, the front case does not come off in use or on external impact, and the front case fixing element is not exposed to the outside of the device, thus providing excellent design.
