ABSTRACT:
A door handle includes a damper wherein a difference in torque changed according to a rotational direction becomes large. A rotor and a valve are completely separated and only the rotor rotates, so that it is possible to significantly reduce torque applied to the rotor. When the rotor and the valve are connected or separated, torque applied to the rotor is changed greatly. Accordingly, instead of gradually changing torque according to a rotational angle of the rotor, it is possible to set a specific point where torque is changed.
