A server realizing network communication number service is provided. Distal portions of deflection wires are connected to the shaft. An antisettling additive is present in the conductive thermoset material to support dispersion, optionally, homogenous dispersion of the conductive material in the resin. In one embodiment, the support mounted to the rail has upper and lower bars that are parallel to each other with a space between the two. Thereby the door hinge device can be compact, in which the checking-force generating mechanism can be disposed in the outer cylinder without increasing the diameter of the outer cylinder.
