PURPOSE:To smooth the opening and closing motion of a door and to simplify a function by a method wherein a moving member having viscous shearing resistance, a one-way clutch part to engage and disengage the moving member, and a power generating part are formed integrally, and disposed to a moving part for opening and closing a door. CONSTITUTION:A one-way clutch part 7' engages and disengages a moving shaft 3 with and from a moving part 4, generating viscous shearing resistance through rotation of viscous fluid C, according to the rotation direction of the moving shaft 3 rotatable through opening and closing of a door. The one-way clutch part and a power generating part 7'' of a spring are integrally formed through a coil spring 7. A part of the coil spring 7 is pressed in the moving member 4. The opening and closing motion of a door is smoothed through the coil spring 7 and resistance produced by a viscous shearing force. This constitution simplifies a function and reduces size compared with a device in which a spring for generating a power and a one-way clutch are separately formed. |
