Provided is a door handle device which can prevent rattling of a handle grip using an existing base member. A door handle device includes: a base member having a first shaft portion or a first bearing portion formed on one end side thereof, and having a guide hole which has a restricting portion projecting into an inner space formed on the other end side thereof; a handle grip having a second bearing portion which rotatably supports the first shaft portion or a second shaft portion which is rotatably supported by the first bearing portion on one end side thereof, and having an inserting portion advanceable into and retractable from the guide hole formed on the other end side thereof; and a slide guide having a slide contact portion which is brought into slide contact with the restricting portion.

Door handle device

An antenna unit incorporated into a door handle of a vehicle includes: an unlock sensor plate (first detection electrode) of a capacitive sensor configured to detect a driver's approaching or touching the door handle; and an antenna for wireless communications. The unlock sensor plate has an antenna fixing part for positioning and fixing the antenna. The antenna fixed on the antenna fixing part and the unlock sensor plate are molded into a unit with a molded resin. The unlock sensor plate has a circuit board fixing part for positioning and fixing a circuit board including a detection circuit of the capacitive sensor mounted thereon. An electrode fixing part for positioning and fixing a lock sensor plate (a second detection electrode) of the capacitive sensor is provided on an opposite surface of the circuit board from a surface on which the unlock sensor plate is arranged.

Antenna unit and door handle device including the same

Provided is a door lock system for locking a rear door to a vehicle body of a vehicle in which an ingress/egress opening is opened and closed by a front door and the rear door being double opening doors, comprising: a disablement mechanism for switching an inner handle and latch units between connected/unconnected states, the inner handle provided in the rear door, the latch units being capable of keeping the rear door closed to the vehicle body; a base member provided with the disablement mechanism; and an operation member coming into contact with the front door, working in response to the opening-and-closing of the front door, and switching the disablement mechanism between connected/unconnected states, wherein the door lock system is provided in a front end portion of the rear door, and the operation member to come into direct contact with the front door is movably provided in the base member.

Door lock system

A door handle device includes: a base member having handle supporting portions provided between a pair of supporting boards facing each other; a handle grip provided with an arm portion protruding at one end of the handle grip, shaft support portions provided on an extreme end of the arm portion and pivotally supported by the handle supporting portions of the base member, and an operating portion provided at the other end of the handle grip and configured to operate a lever provided on the base member; and a double torsion spring having a restriction portion extending between the pair of supporting boards of the base member, and hooked to the supporting boards of the base member by its own biasing force, in which a recessed portion with which the restriction portion of the double torsion spring is engaged is formed in the arm portion of the handle grip.

The invention can securely carry out an operation by a reduced number of the parts. The invention is provided with a base member having a gear lever arranged portion and a pinion member arranged portion, and provided with a communication hole communicating with the gear lever arranged portion in a closed wall portion of the pinion member arranged portion, a gear lever rotatably arranged in a bearing portion, having a gear portion and driving an output member (a control wire) based on a rotation, a pinion member rotatably arranged in the pinion member arranged portion and having a pinion portion engaging with the gear portion via the communication hole, a holder having a retention portion retaining the pinion member in one end, and having a fixing portion fixing to the base member in the other end, and an operation knob arranged so as to be outside fitted to the pinion member and integrally rotating the pinion member.
