This spring is a flexible coil spring, which is coupled between the base member and the slide member through a plurality of rivet joints, and passes through a certain point during the movement of the slide member, thereby pushing the slide member by the repulsive force of the spring. .

Here, in the related art, the operating force is adjusted by changing the spring, so that it is difficult to adjust the operating force for each moving section. When the spring is changed, excessive load is applied to the end of the spring, thereby causing damage. In addition, since the parts to serve as a guide for changing the direction of the spring must be additionally provided, there is a problem in that the production cost of the slide module increases the assembly cost in the production of the slide module.
