Description

  The present invention relates to an automobile door handle device.

  Recently, in automobiles that perform door locking / unlocking control using electronic authentication means such as radio, unlocking operation using a mechanical key is performed to avoid lock control failure due to failure of electronic authentication means. There is a case where a cylinder lock capable of performing the above is prepared. Since the cylinder lock provided for this purpose is used less frequently, there are fewer opportunities for self-cleaning of dust and the like associated with operation using the mechanical key. It is desirable to prevent.

  As a door handle device capable of preventing entry of dust or the like into the cylinder lock, for example, the one described in Patent Document 1 is known. In this conventional example, the door handle device is formed by fixing a cylinder lock to an escutcheon (handle base) to which a handle body is connected.

Since the cylinder lock is disposed behind the handle body in a non-operating state, the cylinder lock is not exposed to the outside when the handle body is not operated, and the chance of attaching dust or the like is reduced.
