Patent ID: 8408610

Claim:
A door handle apparatus for a vehicle comprising: a door handle including a first handle case and a second handle case, the first handle case having a holding portion for holding the door handle, the holding portion being arranged to be distant from an outer surface of an outer panel of a vehicle door by a clearance, the second handle case serving as an outer portion of the door handle and being arranged to cover the first handle case; a rotational-portion extending portion provided in the vicinity of one end portion of the door handle in a longitudinal direction thereof and extending into the outer panel after passing therethrough to connect a rotational portion that is rotatably supported by a supporting member inside the outer panel; and an operational-portion extending portion formed in the vicinity of the other end portion of the door handle in the longitudinal direction thereof and extending into the outer panel after passing therethrough to connect an operational portion operating an opening and closing mechanism of the vehicle door, the operational-portion extending portion being provided with a lock detection electrode of an electrostatic capacity sensor, the lock detection electrode being arranged to face an inner surface of the second handle case facing the outer panel, the electrostatic capacity sensor detecting that a door lock command is inputted, on the basis of a fluctuation of electrostatic capacity, wherein the lock detection electrode includes an upper lock detection electrode and a lower lock detection electrode arranged to face an inner surface of an upper wall of the second handle case facing the outer panel and an inner surface of a lower wall of the second handle case facing the outer panel, respectively, wherein the upper lock detection electrode establishes a first capacitive coupling with the outer panel and the lower lock detection electrode establishes a second capacitive coupling with the outer panel, and wherein a first electrode end surface of the upper lock detection electrode and a second electrode end surface of the lower lock detection electrode, each of which faces the outer panel, are formed into different shapes from each other, so that a level of the second capacitive coupling established between the lower lock detection electrode and the outer panel is set to be smaller than a level of the first capacitive coupling established between the upper lock detection electrode and the outer panel.
