The present invention relates to an elastic member for a sliding module used in a mobile phone of a sliding method, and more particularly, the elastic member for a sliding module is located on the left and right sides of the elastic member, respectively, on the rod moving in the transverse direction. A plurality of guide shafts are fixed and attached, and a spring is inserted into the guide shafts, and then the rods to which the guide shafts are attached are formed by engaging the body parts. In addition, in order to prevent shaking due to the movement of the rod in the lateral direction, by inserting the pin shaft through each rod and the body portion to configure the elastic member, it is possible to simplify the assembly process and improve the performance of the elastic member An elastic member for a sliding module.

The elastic member of various structures is used for the mechanism or apparatus which needs elastic force. An elastic member that provides an elastic force is mainly used in a sliding module, and a representative mobile phone of the sliding module is a sliding type phone.

Mobile phones for providing wireless communication services have become a necessity of people, and these mobile phones are manufactured in various forms (for example, bar type, flip type, and folding type) to suit people's preferences.

However, the bar type mobile phone has a problem in that the keypad is exposed to the outside and the keypad is easily damaged. In the flip type mobile phone proposed to solve this problem, the problem of the bar type mobile phone is solved by covering the keypad with a flip. However, the flip type mobile phone has a long length of the main body, which is inconvenient to carry.

In order to reduce the length of the main body of the bar-type and flip-type cell phones, a clamshell cell phone is proposed. The clamshell cell phone has a structure that can open and close a folder during a call or a cell phone. Connecting hinge parts are easily damaged.

In order to solve the problem of the clamshell mobile phone, a sliding type mobile phone has been proposed, and a conventional sliding type mobile phone has a sliding module between a receiving unit having a liquid crystal display and a calling unit having a keypad.
