PURPOSE: A hinge mechanism and a mechanical joint using a volume change of urethane or resin are provided to maintain tilting properties for a long time by easily restoring the tilting properties. CONSTITUTION: A hinge mechanism and a mechanical joint using a volume change of urethane or resin comprises a support tab(2), a coupling member, and an elastic friction member(4). The coupling member comprises a frictional force control bolt(3) and a rotary cap(5). The frictional force control bolt is rotatably coupled to the support tab. The rotary cap is axially moved by the frictional force control bolt, and pressurizes the elastic friction member. The elastic friction member is composed of urethane or resin, and changes the frictional force of the support tab and the coupling member. |
