DOOR HANDLE DEVICE

摘要

Disclosed is a door handle device capable of operating the door opening/closing mechanism of a vehicle. The door handle device comprises a support member (21), a door handle (10), a circuit substrate (30), a lock detecting electrode (31), an electrostatic capacity sensor (41), and an auxiliary electrode (35). The circuit substrate (30) is disposed in the door handle (10), and has an earth electrode (GNDB). The lock detecting electrode (31) is so mounted on the circuit substrate (30) that it may be coupled in an electrostatic capacity to an outer panel (20) of the door. The electrostatic capacity sensor (41) is connected with the lock detecting electrode (31), and detects the issuance of a door locking command on the basis of the change in a first electrostatic capacity (CPANEL) between the outer panel (20) and the lock detecting electrode (31). The auxiliary electrode (35) is coupled in such an electrostatic capacity to the earth electrode (GNDB) that a second electrostatic capacity (CBOARD) to be connected in parallel with the first electrostatic capacity (CPANEL) may be interposed between itself and the earth electrode (GNDB).
