<p><P>PROBLEM TO BE SOLVED: To provide a door handle device and a keyless entry device having this device, capable of controlling opening-closing operation, by using a piezoelectric sensor having a flexible structure, and providing sufficient detecting sensitivity even at a light touch. <P>SOLUTION: This door handle device 100 is arranged on a door 13 having a handle 11 for opening-closing operation, and can release a lock of a door lock means for locking door opening operation of this door 13 by operation of the handle 11. The door handle device is provided with the piezoelectric sensor 15 arranged on the handle 11, and formed of a flexible piezoelectric element, and a control part for releasing the lock by the door lock means, by receiving a detecting signal from the piezoelectric sensor 15 generated by contact with the handle 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
