Abstract

A hinge module of a cellular phone according to the present invention, includes: a first rotation member, connected to a first body, having the substantially same rotaional displacement as the first body; a second rotation member, connected to a second body, having the substantially same rotaional displacement as the second body; and a first elastic body connected to the first and second rotation members to provide elastic force in a direction opposite to the any one of the rotaional displacement of the first and second rotation members, wherein the first rotation member comprises a cylindrical housing having an opening at one end thereof and a cover to open/close the opening of the housing, wherein the second rotation member comprises a fixing cam inserted into the housing and a pin shaft being installed to be substantially coaxial to a rotation axis of the first and second rotation members to pass through the fixing cam to restrict the fixing cam and having a fixing projection restricting the fixing cam and a projected part connected to the second body, wherein one end of the first elastic body is connected to the cover and the other end is connected to the fixing cam.
