  By providing the protector 7 as described above, the internal space S is communicated with the space S1 in which the flange portion 6b of the key lever 6 and the key rod 5 are disposed, and the space d2 between the side door body 1 and the side window 2. And is defined. Therefore, even if the tool 10 is inserted through the gap d1 between the side door body 1 and the side window 2 and the key lever 6 of the door lock device 3 is operated, the tool 10 is prevented from entering by the protector 7, and the tip of the tool 10 is The key lever 6 is not reached. Therefore, unauthorized unlocking of the door lock device 3 can be prevented.

  Even if the key rod 5 is to be removed from the key cylinder 4, the tool 10 is prevented from entering by the protector 7, and the tip of the tool 10 does not reach the key rod 5. Unauthorized unlocking can be prevented.

  Thus, in this embodiment, the protector 7 is attached in order to achieve the antitheft performance. However, in order to avoid interference between the protector 7 and the door lock device 3 (key lever 4) and to improve the workability of assembling the door lock device 3 into the side door body 1, the protector 7 and the door It is necessary to set a certain gap between the locking device 3 and the locking device 3. For this reason, if the protector 7 is merely provided, an entry path to the key lever 6 of the tool 10 for performing unauthorized unlocking is formed, although only slightly.

  Therefore, in this embodiment, the cover 9 is restricted from entering the tool 10 through the gaps d2 and d3 formed between the edge portions 71c and 72a of the protector 7 on the door lock device 3 side and the door lock device 3. Formed a regulation section.

  Specifically, as a restricting portion that protrudes in a direction intersecting the intrusion direction of the tool 10 and protrudes so as to overlap with end edge portions (edge portions) 71c and 72a on the door lock device 3 side of the protector 7. Protrusions 91 and 92 were formed on the cover 9.

  In the present embodiment, a rib-shaped protruding portion 91 protruding upward is formed on the upper surface 9 a of the cover 9. That is, the projecting portion 91 is formed so as to project upward, which is a direction orthogonal to (crossing) the vehicle width direction (inner / outer direction: left-right direction in FIG. 2), which is the entry direction of the tool 10a. Furthermore, the protrusion 91 is protruded so as to overlap with the edge 71c of the upper protector 71 on the side of the door lock device 3 by D1 when viewed from the intrusion direction of the tool 10a (the left-right direction in FIG. 2). At this time, the gap d2 formed between the edge 71c of the upper protector 71 on the door lock device 3 side and the door lock device 3 (in this embodiment, the cylindrical portion 6a of the key lever 6) is intruded by the tool 10a. It will be covered with the protrusion 91 in the state seen from the direction (left-right direction in FIG. 2). Further, in the present embodiment, as shown in FIG. 4, the protruding portion 91 is formed so as to protrude not only upward but also in the vehicle front-rear direction and downward. That is, the protruding portion 91 protrudes in the radial direction of the cylindrical portion 6a of the key lever 6, and is formed so as to substantially surround the periphery of the cylindrical portion 6a. The protruding portion 91 is simply protruded from the cover 9 and is not connected to the end edge (edge) 71c of the upper protector 71 on the door lock device 3 side.

  Further, a flange-shaped protruding portion 92 that protrudes outward is formed on the side surface (outer side surface) 9 b of the cover 9. That is, the protruding portion 92 is formed so as to protrude outward (width direction), which is a direction orthogonal to (intersects with) the vertical direction as the penetration direction of the tip of the tool 10b. Furthermore, in a state viewed from the intrusion direction of the tool 10b (vertical direction in FIG. 2), the protruding portion 92 is overlapped with the end edge portion (edge portion) 72a on the door lock device 3 side of the lower protector 72 by D2. Is protruding. At this time, the gap d3 formed between the edge (edge) 72a on the door lock device 3 side of the lower protector 72 and the door lock device 3 (the side surface 9b of the cover 9 in this embodiment) The tool 10b is covered with the protruding portion 92 in a state viewed from the intrusion direction (vertical direction in FIG. 2). The protrusion 92 is also simply protruded from the cover 9 and is not connected to the end edge (edge) 72a of the lower protector 72 on the door lock device 3 side.

  Thus, in the present embodiment, the protrusions 91 and 92 are closer to the front side (inner side and lower side) of the tool 10 than the end edges (edges) 71c and 72a of the protector 7 on the door lock device 3 side. ). That is, the protrusions 91 and 92 are formed such that the positions in the intrusion direction of the tool 10 are offset from the end edges (edges) 71c and 72a of the protector 7 on the door lock device 3 side. Thus, by forming the protrusions 91 and 92, a path bent in a U shape or a crank shape is formed on the space S2 side in the vicinity of the gaps d2 and d3. In the present embodiment, the protruding portions 91 and 92 are integrally formed with the cover 9.

  As described above, in the present embodiment, the tool 10 from the gaps d2 and d3 formed between the edge portions 71c and 72a on the door lock device 3 side of the protector 7 and the door lock device 3 is attached to the cover 9 in the present embodiment. It forms a regulation part that regulates intrusion. Therefore, even if the tool 10 is inserted through the gap d1 between the side door body 1 and the side window 2, the gaps d2 and d3 between the edge portions 71c and 72a of the protector 7 on the side of the door lock device 3 and the door lock device 3 are used. Intrusion of the tool 10 into the space S1 in which the key lever 6 and the key rod 5 are disposed is restricted by the restricting portion.

  By the way, when the cover 9 is not provided with the protrusion 91, the tool 10a is moved from the gap d2 by sliding the tool 10 (the tool 10a in FIG. 2) along the surface of the door lock device 3 (the upper surface 9a of the cover 9). There is a possibility that the space 10 enters the space S1 and the tip of the tool 10a reaches the key lever 6 to be illegally unlocked. However, by providing the protrusion 91 on the cover 9, even if the tool 10a is slid along the surface of the door lock device 3 (the upper surface 9a of the cover 9) as shown in FIG. Before entering from the gap d2, the protrusion 91 is contacted to restrict the tool 10a from entering. Thus, even if it is going to make the tool 10a reach the key lever 6 for the purpose of unauthorized unlocking, since the intrusion of the tool 10a into the space S1 is restricted by the protruding portion 91, the anti-theft performance can be further improved. .

  Further, when the cover 9 is not provided with the protruding portion 92, the tool 10b enters the space S1 from the gap d3 by turning the hook-shaped tool 10b (see FIG. 2) to the lower side of the door lock device 3, There is a possibility that the tip of the tool 10b reaches the key lever 6 and unauthorized unlocking is performed. However, by providing the projection 92 on the cover 9, even if the hook-shaped tool 10b (see FIG. 2) is turned to the lower side of the door lock device 3 as shown in FIG. Before entering from the gap d3, the protruding portion 92 is contacted and the entry of the tool 10b is restricted. Thus, even if it is going to make the tool 10b reach the key lever 6 for the purpose of unauthorized unlocking, since the intrusion of the tool 10b into the space S1 is restricted by the protruding portion 92, the anti-theft performance can be further improved. .

  Further, according to the present embodiment, the protrusions 91 and 92 are formed so that the positions in the intrusion direction of the tool 10 are offset from the edge portions (edge portions) 71c and 72a of the protector 7 on the door lock device 3 side. doing. That is, a path bent in a U shape or a crank shape is formed on the space S2 side in the vicinity of the gaps d2 and d3. Therefore, even if the tool 10a or the tool 10b gets over the rib-shaped protrusion 91 or the flange-shaped protrusion 92 and enters the vicinity of the key lever 6, the tool shape is maintained when the soft tool 10 is used. Unable to unlock. In addition, when the hard tool 10 is used, a rubbing force is generated with the protrusions 91 and 92, so that the elastic deformation of the tool 10 is induced, and the key lever 6 is illegally operated at the tip of the tool 10. Can be difficult.

  Thus, according to this embodiment, it can suppress more reliably that the key lever 6 will be operated with the tool 10, and can improve crime prevention performance more.

  Moreover, in this embodiment, the protrusion part 91 protrudes in the radial direction of the cylindrical part 6a of the key lever 6, and is formed so that the circumference | surroundings of the cylindrical part 6a may be enclosed. Therefore, even if the tool 10a is slid along the surface 9c in the front-rear direction while sliding along the surface of the door lock device 3 (the upper surface 9a of the cover 9), the protrusion of the tool 10a into the space S1 is projected. It becomes possible to regulate by 91, and anti-theft performance can be further improved.

  Moreover, in this embodiment, the protrusion parts 91 and 92 are formed in the cover 9 provided for waterproofing. Therefore, it is not necessary to provide a new member for the anti-theft property, and the increase in cost can be suppressed. Furthermore, there is also an advantage that the defense performance against unauthorized unlocking of the door lock device can be further improved without deteriorating the assembling workability.

  The protector structure of the vehicle door lock device according to the present invention has been described above by taking the above embodiment as an example. However, the present invention is not limited to the above embodiment, and other implementations are possible without departing from the spirit of the present invention. Various forms can be adopted.
