OPENING AND CLOSING DEVICE FOR DOOR
Document Type and Number:
Japanese Patent JP3899912
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an opening and closing device for a door capable of coping with space saving when a request signal resonance circuit for transmitting a request signal and a sensor resonance circuit for detecting the approach of a person based on electrostatic capacity are set in a door handle.
SOLUTION: The opening and closing device is set in the door handle for opening and closing a vehicle door 3, it is equipped with an antenna 10 generating a magnetic field component to the outside by resonance and a sensor electrode 19 set in the door handle 2 and varying in electrostatic capacity by the approach of the person to the door handle 2, the antenna 10 is equipped with a second antenna 52 comprised of a coil 55 and resonance capacity C2, and the sensor electrode 19 comprises the second antenna 52.
