FIG. 6 is an enlarged view of the 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, a screw protection portion 6d, and a forward / backward movement preventing portion 6e. And is formed by pressing one plate of steel. Since steel is used, the protection member 6 is very 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 with a mounting screw 7.

The screwing portion 6a is obliquely bent so that the surface thereof is oriented in the direction orthogonal to the direction in which the screw hole of the screw mounting portion 4c of the key cylinder 4 extends, rather than the direction of the door edge. There is. A screw penetration portion 6b is formed in the screw fastening portion 6a.
The screw penetrating portion 6b is a through hole through which the mounting screw 7 penetrates, and by tightening the mounting screw 7 from the temporarily assembled state of the protective member 6 (see FIG. 8), the protective member 6 is inserted in the state where the mounting screw 7 penetrates. It is formed as an elongated hole so that it can slide.

  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. The peripheral base member 2 is protected 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 outer surface side of the door panel 8 to the inner surface side (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 have to completely cover the screw mounting portion 4c, and if the screw mounting portion 4c is partially covered, it is possible to make destruction difficult.

  The advance / retreat blocking portion 6e extends in parallel to the peripheral protection portion 6c in a direction away from the edge side (to the right in FIGS. 4 and 5) and is also formed in parallel with the peripheral protection portion 6c. There is. The advancing / retreating portion 6e is formed on the inner surface side of the door panel 8 with respect to the surrounding protection portion 6c, and inhibits the advancing / retreating of the key cylinder 4 in the insertion direction at the assembly completion position where the mounting screw 7 is tightened. The advancing / retreating portion 6e engages with the key cylinder 4 in both the direction in which the base member 2 is sandwiched with the surrounding protection portion 6c and the key cylinder 4 is removed and pushed in.

  As described above, the engagement recess 4d is formed on the sleeve 4f and the housing 4g that cover the key cylinder body 4e. Therefore, the protection member 6 of the present embodiment is generally used as a component for fixing a key cylinder component so as not to move in the key insertion direction, which is commonly used for fixing a key cylinder. The function of the stopper plate is included.

  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 perimeter protection part 6c protects the periphery of the key cylinder 4 and the advance / retreat blocker 6e prevents the key cylinder 4 from advancing / retreating, it is wider when the key cylinder 4 is to be removed. You will have to destroy the area, making it difficult to destroy.

  The protective member 6 of the present embodiment has a configuration in which the peripheral protective portion 6c is housed inside the base member 2. However, without being limited to such a form, for example, the peripheral protection portion 6c may be arranged on the front side of the base member 2, or conversely, the peripheral protection portion 6c may be arranged on the inner side of the base member 2. You may arrange.

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 installation portion 2e of the base member 2. Further, the mounting screw 7 is only temporarily assembled. When the position of the protective member 6 becomes indefinite, for example, the base member 2 may be provided with a locking shape or the like that can temporarily hold the position of the protective member 6.

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.
When the grip member 1 is assembled to the base member 2 and then the key cylinder 4 is assembled after the state of FIG. 7, the state of 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 into a predetermined position. When the mounting screw 7 is tightened, the key cylinder 4 and the protection member 6 are connected 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. The screw penetration portion 6b of the protection member 6 is provided between the screw head of the mounting screw 7 and the base member penetration portion 2f of the base member 2.
With this configuration, when the screw tip of the mounting screw 7 is inserted into the screw mounting portion 4c of the key cylinder 4 and the mounting screw 7 is tightened, the protection member 6 pressed by the screw head slides in the mounting portion 2e. Then, the forward / backward movement preventing portion 6e is engaged with the engagement concave portion 4d of the key cylinder 4.

  Further, since the screw mounting portion 4c of the key cylinder 4 is arranged on the door edge side, the mounting screw 7 can be tightened from the door edge side when the door handle device 10 is assembled. Assembly of the door handle device 10 is often performed in a state where the door has already been installed in 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.

  Further, 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 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 by 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 an appropriately compressed state, and the assembly is performed without any unnecessary gap. Done. As a result, it is possible to prevent the components 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 high-strength protective member 6 arranged around the key cylinder insertion portion 2c into which the key cylinder 4 is inserted. It is possible to prevent the act of destroying the member 2.
Further, since the door handle device 10 connects the protective member 6 and the key cylinder 4 to the base member 2 with one mounting screw 7, even if the base member 2 is broken, the key cylinder 4 can be easily removed. Without being removed, the anti-theft property is improved.
Further, the protection member 6 is formed with the forward / backward movement preventing portion 6e for preventing forward / backward movement of the key cylinder 4 in the insertion direction. Therefore, when the key cylinder 4 is improperly pushed or pulled out, only the mounting screw 7 is used. Without it, the protective member 6 can also receive the force of tampering, and the resistance against the pushing and pulling of the key cylinder 4 can be greatly improved.

Further, since the door handle device 10 has the protective member 6 formed by press working using one plate material (for example, made of steel), it can be a protective member having high strength.
Furthermore, since the peripheral protection portion 6c formed on the protection member 6 is formed at a position that covers the periphery of the key cylinder 4, if the key cylinder 4 is to be removed illegally, a wide area is destroyed. It becomes necessary to protect the key cylinder 4 from being destroyed by fraudulent acts such as hitting and destroying the periphery of the key cylinder 4.
Further, since the forward / backward movement preventing portion 6e that engages with the key cylinder 4 is formed integrally with the protection member 6 and the base member 2 is sandwiched between the forward / backward movement preventing portion 6e and the peripheral protection portion 6c, the periphery of the key cylinder 4 is prevented. It is possible to protect the resin base member 2 from breakage, and it is possible to achieve an improvement in the resistance against the pushing or pulling of the key cylinder 4 with a simple configuration.
Further, 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 the screw fastening portion 6a and the protection member 6 are integrally formed without being a separate member. Since it is formed, the strength of the screw fastening portion 6a can be increased.

Further, in the door handle device 10, the arranging portion 2e for arranging the protective member 6 is formed so as to intersect the insertion direction of the key cylinder 4, and the protective member 6 is arranged around the key cylinder 4. Because of the structure, the key cylinder 4 has high resistance against pushing and pulling.
Further, without any change from the assembling work of tightening the mounting screw 7 and fixing the key cylinder 4 to the base member 2, by tightening the mounting screw 7, the protective member 6 slides the disposition portion 2e. Thus, the advance / retreat blocker 6e and the key cylinder 4 can be engaged with each other.

  Furthermore, since the protection member 6 has a screw protection portion 6d formed at a position that hides the screw mounting portion 4c from the outside so as not to be destroyed, protect the peripheral portion of the mounting screw 7 from being destroyed by fraudulent acts. You can
