Claim 0:
1. A door handle structure of a vehicle, comprising:
a hinge arm having a lever which is retractable from a door panel at one end thereof and a rotational axis to rotate the lever so as to be projected from the door panel; and
a driving unit to transmit a drive force to the hinge arm so as to project the lever from the door panel,
wherein said lever is configured to be rotatable among a storage position where the lever is flush with the door panel, a gripping position where the lever is projected from the door panel by said driving unit so that a user is able to grip the lever, and an open position where the lever is further projected from said gripping position,
the lever is biased in a storage direction by a biasing mechanism which is provided at said rotational axis,
a switch which is electrically connected to said driving unit is provided to closely face a vehicle inward side of the lever taking the storage position,
said driving unit comprises a motor and an output axis which is connected to said motor and said hinge arm so as to transmit an output of the motor to the hinge arm in a region from the storage position to the open position, and
said driving unit is configured such that a motor drive force is transmitted from the motor to the hinge arm via said output axis when the lever is moved from the storage position to the gripping position and a hinge arm drive force is transmitted from the hinge arm to the motor via said output axis when the lever is moved from the open position to the gripping position,
wherein a bracket rotatably supporting the hinge arm via said rotational support axis is provided, said driving unit comprises a crank which is fixed to said output axis at a base end thereof and has a slide member at a free end thereof, and a guide portion to guide a moving path of said slide member is provided at said bracket, and
a roller as said slide member is rotatably provided at an axis portion which is provided at the free end of said crank, and a ring-shaped guide rib as said guide portion extending downwardly from an upper wall of said bracket is integrally formed at said upper wall of the bracket in order that said roller guides a moving path of said lever from the storage position to the open position by way of the gripping position.
