している。2. Description of the Related Art A key cylinder device is usually used for locking and unlocking an automobile door (see Japanese Utility Model Laid-Open No. 62-27966). this is,
It consists of a key cylinder that is linked to the door locking and unlocking mechanism via a link, and a cylindrical key cylinder case that locks and locks this key cylinder to fix it to the door. In this key cylinder case, a ridge corresponding to a groove that engages with the engagement protrusion on the key cylinder side is formed on the outer circumference. On the other hand, an infrared keyless entry device has also been developed in which an infrared remote control device is used to drive an actuator and the drive force is used to operate a door locking and unlocking mechanism. Here, the keyless entry device is often used together with a key cylinder device. In this case, in the infrared method, an infrared light receiving portion is arranged near the key cylinder to facilitate the position confirmation.

赤外線受光部の取付位置精度および取付け作業性を向上
することを目的とする。By the way, when looking at the mounting structure of the infrared ray receiving part, it is common to use a type that two-point screws are attached to the escutcheon of the door handle, and the positioning accuracy is poor and the workability of mounting the escutcheon from the receiving window is poor. There is a problem. Therefore, an object of the present invention is to improve the mounting position accuracy and mounting workability of the infrared light receiving portion with respect to the escutcheon of the door handle.

止め固定してなる。To this end, the present invention relates to an infrared ray receiving portion for keyless entry arranged near a key cylinder, in which one outer circumference is engaged with a groove on a convex portion of a key cylinder case to which the key cylinder is fitted and fixed. By this engagement, the rotation is restricted by this engagement, and the door handle is fixed to the escutcheon with a one-point screw.

光窓2aに対する位置ズレが防止される。An embodiment of the present invention will be specifically described below with reference to the drawings. In FIG. 3, reference numeral 1 is a door handle of an automobile, and 2 is an escutcheon of the door handle. A key cylinder 3 is arranged on the escutcheon 2 and an infrared ray receiving portion 2a is formed above it. The key cylinder 3 is connected to a door locking / unlocking mechanism through a link (not shown).
It is inserted into a cylindrical key cylinder case 4 integrally formed with (see FIG. 2). This key cylinder case 4
A concave groove 4a that engages with an engaging protrusion 3a provided on the outer periphery of the key cylinder 3 to prevent the engagement protrusion 3a from rotating is provided on the inner periphery of the key cylinder 3 along the longitudinal direction. As shown in FIG. 1, the ridge 4b is formed. A snap ring 5 is attached to the notch 4c formed in the ridge 4b so as to prevent the engagement protrusion 3a of the key cylinder 3 from coming off. Here, the infrared light receiving portion 6 in the infrared type keyless entry device is arranged on the back surface of the escutcheon 2 corresponding to the infrared light receiving portion 2a. This infrared light receiving section 6 is
The concave groove 6a formed on the lower surface of the key cylinder case 4 is engaged with the convex groove 4b of the key cylinder case 4 to be positioned, and the protruding piece on the upper side thereof is positioned.
6b is a mount for the escutcheon 2 via one screw 7.
It is fixed to 2b with screws. In the above configuration, the infrared receiving section 6 is restricted from rotating around the screw 7 by the engagement of the concave groove 6a and the convex strip 4b, and maintains a constant positional relationship with the key cylinder case 4. A position shift with respect to the window 2a is prevented.

業性が良い。As described above, according to the present invention, the infrared ray receiving portion is fixed to the escutcheon of the door handle while maintaining a fixed positional relationship with the key cylinder case, so that the mounting position accuracy is improved. Therefore, the infrared light receiving portion does not shift from the light receiving window of the escutcheon, and the aesthetic sense near the door handle is improved. Also, since there is only one screwing point, workability such as mounting is good.
