<p>PROBLEM TO BE SOLVED: To provide a control device for an opening/closing door which is capable of appropriately maintaining the elevating/lowering speed of the opening/closing door without dependent on the change in temperature. SOLUTION: A control device is provided with a second transmission member 30 fixed to form a working chamber 40 in which a viscous fluid is sealed together with a first transmission member 20, a rotary plate set 50 which is arranged in the working chamber 40 and engaged with the first transmission member 20 in a relatively non-operational manner, and a fixed plate set 60 which is alternately arranged to the rotary plate set 50 and engaged with the second transmission member 30 in a relatively non-operational manner. In addition, an elastic means 80 is arranged between the fixed plate sets 60, and a temperature sensing means 70 which senses the atmospheric-temperature by exposing one end thereof outside the working chamber 40, and adjusts the interval between the fixed plate set 60 and the rotary plate set 50 according to the atmospheric temperature is provided.</p> |
