ABSTRACT:
A door handle system includes a door opening lever rotationally supported on a support member, and a damper having a linear piston sliding mechanism. The door opening lever has an angle change device for changing an angle when the door opening lever is actuated. The damper is attached to the support member and arranged to contact the angle change device so that a returning force of the door opening lever after being opened is reduced by the damper.
