Claim:
A sliding portable terminal, comprising: a first case; a second case having a protruded part extending in a protruding direction toward the first case; a first connecting portion connected to the first case; a second connecting portion connected to the second case and slidably coupled to the first connecting portion for sliding between an open state and a closed state; and an elastic portion configured to provide, in the open state, a force to keep the open state, and, to provide, in the closed state, a force to keep the closed state, the elastic portion having a center coil portion between one end and an other end of the elastic portion, wherein in the opened state and the closed state, the center coil portion includes a large-diameter portion and a small-diameter portion which are spiraled and layered in a layered direction, wherein, when projected in a plane perpendicular to the layered direction, the small-diameter portion is disposed at a substantially opposite position to a position where the spiral of the large-diameter portion starts and ends, with respect to a center of the large-diameter portion, wherein a first side space and a second side space are formed between the first connecting portion and the second connecting portion in the closed state, the first side space disposed outward of the protruded part in a direction perpendicular to both the sliding direction and the protruding direction, and the second side space disposed outward of the protruded part in a direction perpendicular to the protruding direction and parallel to the sliding direction, and in the closed state, the one end of the elastic portion fixed to the first connecting portion is disposed in the first side space, and the other end of the elastic portion fixed to the second connecting portion is disposed in the second side space.
