A purpose of this invention is to provide a door handle device by using a piezoelectric sensor which has a pliable structure and which provides sufficient detection sensitivity even with a light-touch, thus making it possible to control the opening and closing operation; and a keyless entry device having the same. A door handle device (100) is designed such that a door lock means which is installed on a door (13) having a handle (11) for opening and closing operation and which locks the door opening operation for this door (13) is unlocked by the operation of the handle (11). The door handle device is provided with a piezoelectric sensor (15) disposed on the handle (11) and formed of a piezoelectric element having flexibility, and a control section adapted to receive a detection signal from the piezoelectric sensor (15) produced by contact with the handle (11), and to cancel the lock imposed by the door lock means.

Cette invention vise, d'une part, un dispositif de poignée de porte qui utilise un capteur piézo-électrique muni d'une structure pliable et possédant un degré de sensibilité de détection suffisant pour réagir même à un effleurement, ce qui permet d'effectuer les opérations d'ouverture et de fermeture; et, d'autre part, un dispositif d'entrée sans clé muni du dispositif en question. Un dispositif de poignée de porte (100) est conçu de telle manière qu'un système de verrouillage de porte monté sur une porte (13) et muni d'une poignée (11), qui assure les opérations d'ouverture et de fermeture et qui verrouille la porte (13), soit déverrouillé par l'action de la poignée (11). Le dispositif de poignée de porte est muni d'un capteur piézo-électrique (15) disposé dans la poignée (11) et formé d'un élément piézo-électrique flexible et d'une partie de commande destinée à recevoir un signal de détection provenant du capteur piézo-électrique (15) et formé par le contact de la poignée (11), ainsi que pour enlever le verrouillage produit par le système de verrouillage de porte.
