摘要： A button cover holding mechanism in which an angle between a button cover and a body is constantly maintained when the button cover of a portable telephone is in an open condition, and the button cover is maintained in a closed condition when the portable telephone is in the closed condition, which is more convenient for a user to open and close the button cover. The button cover holding mechanism of a portable telephone has a cylindrical bush, a cylindrical ring and a spring inserted into circular holes of a button cover, covered with a cover mounting projection, and sealed by an ultrasonic connection technique; such that an opposite cylindrical ring is inserted into a reception guide rail of a body by positioning the cylindrical bush of the button cover toward a projection bar of the body, and the cylindrical bush and the cylindrical ring are outwardly positioned by a restoring force of the spring so that a trough portion of the cylindrical bush is assembled in contact with the projection bar. Wave projections of the cylindrical bush and the projection bar of the body are in contact with each other to directly apply the restoring force of the spring to the cylindrical bush; and the restoring force is generated by a change in a moving distance of the spring according to a phase of the cylindrical bush which causes a moment for rotating the button cover, to open and close the button cover.
