Disclosed herein is an elasticity control device for automatic hinges. This elasticity control device for automatic hinges includes a cylindrical housing (10), a shaft (12) axially set in the housing (10), a torison coil spring (13) fitted over the shaft (12) to apply a restoring force to the shaft (112), an elasticity control unit (14) provided at a lower end of the torsion coil spring (13) for controlling elasticity of the spring (13), and a hydraulic speed regulating unit connected to an upper end of the shaft (12) for controlling a rotation speed of the shaft (12). The elasticity control unit (14) has a worm wheel (15) connected to the lower end of the torsion coil spring (13), and a worm (16) installed in the housing (10) and engaging with the worm wheel (15). The worm (16) also has a maninpulation hole (17) at an end of its shaft (12) for allowing a user to rotate the worm (16). |
