A sliding-type mobile communication terminal having a first housing and a second housing opened or closed by means of a sliding movement in a longitudinal direction of the first housing, The terminal includes a spring module adapted to provide a sliding force, along the longitudinal direction, for closing of the second housing within a predetermined range of distance, and for providing the sliding force in an opposite direction for opening of the second housing beyond the predetermined range of distance. The spring module includes link bars rotatably coupled in one end onto the first housing, coil springs supported by one end of the link bar and coupled to enclose the link bar, and a slider slidably coupled to the link bar to be acted upon by an elastic force from the coil spring. The coil springs implement a semi-automatic sliding opening/closure of the second housing.
