FIG. 6 is an enlarged view of a range B in FIG. 2 with the cover member 5 removed. In FIG. 6, the protective member 6 and the mounting screw 7 are indicated by broken lines.

  As shown in FIGS. 1 and 4 to 6, the protection member 6 includes a screw fastening portion 6a, a screw penetration portion 6b, a peripheral protection portion 6c, and a screw protection portion 6d. It is formed by pressing the plate material. Since steel is used, the protection member 6 is extremely strong and extremely effective in preventing unauthorized destruction from the outside. The protection member 6 is fixed to the periphery of the key cylinder insertion portion 2c of the base member 2 by a mounting screw 7.

The screwing portion 6a is obliquely bent so that its surface is in a direction orthogonal to the extending direction of the screw hole of the screw mounting portion 4c of the key cylinder 4 so as to face the inside of the vehicle rather than the direction of the door edge. . A screw penetration portion 6b is formed in the screw fastening portion 6a.
The screw penetration portion 6b is a through hole through which the mounting screw 7 penetrates.

  The perimeter protection portion 6c is formed so as to extend in parallel to the position that covers the periphery of the key cylinder 4 in a direction away from the edge side (to the right in FIGS. 4 and 5), and to the key cylinder insertion portion 2c. It is possible to protect the peripheral base member 2 from unauthorized destruction from the outside.

  The screw protection portion 6d is provided so as to project to a position where the screw mounting portion 4c of the key cylinder 4 is hidden from the inside of the door panel 8 when viewed from the outside (see FIG. 6). This makes it difficult for an unauthorized person to break the screw mounting portion 4c of the key cylinder 4. The screw protecting portion 6d does not need to completely cover the screw mounting portion 4c, and if the screw protecting portion 4c is partially covered, it is possible to make the breakage difficult.

  In the present embodiment, as described above, since the screw protection portion 6d protects the screw mounting portion 4c, it is difficult to make an illegal act to destroy the screw mounting portion 4c in order to remove the key cylinder 4. You can Further, since the surrounding protection portion 6c protects the surroundings of the key cylinder 4, when removing the key cylinder 4, it is necessary to break a wider area, which makes the breaking difficult.

  In addition, most of the protection member 6 of this embodiment is accommodated inside the base member 2. However, without being limited to such a form, for example, the protection member 6 may be arranged on the front side of the base member 2, or conversely, the protection member 6 may be arranged on the inner side of the base member 2.

FIG. 7 is a perspective view showing the door handle device 10 before mounting the grip member 1 and the key cylinder 4.
When assembling the door handle device 10, first, as shown in FIG. 7, the protection member 6 is inserted into the disposition portion 2e of the base member 2. Further, the mounting screw 7 is only temporarily assembled.

FIG. 8 is a view showing the door handle device 10 after mounting the grip member 1 and the key cylinder 4 and before tightening the mounting screw 7.
After the state shown in FIG. 7, the grip member 1 is attached to the base member 2 and then the key cylinder 4 is attached, and the state shown in FIG. 8 is obtained. At this time, the locking portion 4a of the key cylinder 4 comes into contact with the locking portion 2d of the base member 2, and the key cylinder 4 is positioned at the correct position.

FIG. 9 is a perspective view showing the door handle device 10 with the mounting screw 7 tightened from the state of FIG.
As shown in FIG. 9, when the mounting screw 7 is tightened, the mounting screw 7 is screwed into the screw mounting portion 4c of the key cylinder 4 and screwed to a predetermined position. When the mounting screw 7 is tightened, the key cylinder 4 and the protection member 6 are joined with the base member 2 interposed therebetween.
Here, the screw mounting portion 4c of the key cylinder 4 is arranged on the door edge side, and the base member penetrating portion 2f and the screw penetrating portion 6b are arranged so that the mounting screw 7 is inserted from the door edge side. Therefore, when the door handle device 10 is assembled, the mounting screw 7 can be tightened from the door edge side. Assembly of the door handle device 10 is often performed in a state where the door is already mounted on the vehicle. According to the present embodiment, since the mounting screw 7 can be tightened from the door edge side, the work can be easily performed and the work space can be sufficiently secured only by opening the door.

  In addition, the base member penetrating portion 2f and the screw penetrating portion 6b generate a force of a component that pulls the key cylinder 4 toward the inner surface side of the door panel 8 when the mounting screw 7 is tightened. The insertion direction (imaginary line E) of the mounting screw 7 with respect to the imaginary line D in FIG. 5 is arranged so as to intersect at an angle (angle X in FIG. 5) other than perpendicular. Therefore, the resistance to the force of pushing in or pulling out the key cylinder 4 due to the illegal destruction work is high, and the safety can be further enhanced. Moreover, when the mounting screw 7 is tightened, the key cylinder 4 is pulled toward the inner surface side of the door panel 8, so that the sheet member 3 is mounted in a properly compressed state, and the assembly is performed without any unnecessary gap. Done. Accordingly, it is possible to prevent the parts from colliding with each other due to the vibration and causing unpleasant noise.

  As described above, according to the present embodiment, the door handle device 10 has the key cylinder mounting structure in which the high-strength protection member 6 is arranged around the key cylinder insertion portion 2c. The act of destroying can be prevented. Further, since the protection member 6 and the key cylinder 4 are connected by the mounting screw 7, even if the base member 2 is destroyed, the key cylinder 4 is not easily removed, and the antitheft property is prevented. Can be improved.

  Further, the door handle device 10 has a key cylinder mounting structure in which the screw mounting portion 4c of the key cylinder 4, the base member penetrating portion 2f of the base member 2, and the screw penetrating portion 6b of the protective member 6 are arranged on the door edge side. Therefore, the mounting screw can be tightened from the door edge side, and the assembling property can be improved.

  Furthermore, the door handle device 10 is configured to generate a force of a component that pulls the key cylinder 4 toward the inner surface side of the door panel 8 when the mounting screw 7 is tightened in the base member penetrating portion 2f and the screw penetrating portion 6b. The mounting structure of the key cylinder is arranged such that the insertion direction of the mounting screw 7 intersects the key insertion direction of No. 4 at an angle other than perpendicular. Accordingly, the door handle device 10 can bring the sheet member 3 into an appropriately compressed state only by tightening the mounting screw 7, and can prevent unpleasant noise.

  Further, since the door handle device 10 has the key cylinder mounting structure in which the disposition portion 2e of the protection member 6 intersects the insertion direction of the key cylinder 4, the key cylinder 4 is pushed in by an unauthorized destruction work. It is highly resistant to the force of pulling out and pulling out, which can further enhance safety.

Furthermore, in the door handle device 10, since the protection member 6 is formed by pressing a single plate material made of steel, it can be a protection member having high strength.
Further, since the screw protection portion 6d formed on the protection member 6 is formed at a position where the screw mounting portion 4c is hidden from the outside so as not to be destroyed, it is necessary to protect the peripheral portion of the mounting screw 7 from being destroyed by fraudulent acts. You can
Further, since the peripheral protection portion 6c formed on the protective member 6 is formed at a position covering the periphery of the key cylinder 4, it is necessary to destroy a wide area when the key cylinder 4 is illegally removed. It is possible to protect the key cylinder 4 from being destroyed by an improper act such as hitting and destroying the periphery of the key cylinder 4.
Furthermore, in order to tighten the mounting screw 7 from the door edge side, it is necessary to form the screw fastening portion 6a so as to face the door edge, but this is not formed as a separate member but integrally formed by bending. By doing so, the strength of the screw fastening portion 6a can be increased.
