Abstract:
A speed regulator for regulating a closing speed of an automatically closing slide door having a door roller, the closing speed of the slide door being regulated after the slide door has been manually opened, said speed regulator comprising:a generator activated by a rotation of said door roller for suppressing a rotational speed of said door roller; one-way clutch means for preventing transmission of, while said slide door is opening, and transmitting, while said slide door is closing, the rotation of the door roller to said generator; a resistor connected to an output of said generator; and speed change means for changing a closing speed of said slide door, at a predetermined position before a closed position of said slide door, from a first predetermined speed to a second predetermined speed which is slower than said first predetermined speed by changing a resistance value of said resistor.
