The present invention relates to a spring for a slide module, which is applied to a small terminal having a slide module and a electrical line such as a data line or a power line penetrating therethrough, such as a portable communication terminal operating in a sliding system, to reduce the thickness of the terminal employing the spring, and wherein said spring has a structural stability to maintain the elasticity or shape thereof in a good condition, and to thus smoothly assist in the sliding motion of the terminal over a long period of time. The spring for a slide module according to the present invention couples units of a slide-type portable terminal operating when supplied with power such that the units are slidable relative to one another, and comprises a coil unit and a pair of leg units. The coil unit includes an interconnection portion, and a first coil and a second coil which are stacked into layers, in such a manner that at least a portion of the first coil and at least a portion of the second coil are out of line when viewed from the front of the circle of the layer to enable the circle of the layer of the first coil and the circle of the layer of the second coil to have different centers. The leg units are extended in opposite directions, from each end of the first coil and the second coil, and the extended ends of the leg units are rotatably coupled to the slide module. The coil unit and the leg units are formed into a shape in which two sides facing each other are parallel to each other, and the segment perpendicularly interconnecting said two sides has a length shorter than that of any one of said two sides in the cross-section in the thickness direction of the shape. |
