The locking mechanism includes a latch 12 disposed on the front door 1 side and a striker (not shown) attached to the vehicle body side inserted into the groove 13a of the meshing tool 13 shown in FIG. The striker is locked by meshing the striker. This biting tool 13 is fastened to the inner surface of the bent portion 2a formed at the rear end of the inner panel 2 shown in FIG. 5 by inserting bolts (not shown) into the bolt holes 13b to 13d.
A detailed description of the latch 12 and the striker in this lock mechanism is well known and will be omitted.
[0010]
The back side of the key cylinder 6, that is, the inner side of the front door 1 is spaced from the rear end of the key cylinder 6 and between the key cylinder 6 and the window glass 4, as shown in FIGS. A plate-like key cylinder protector 8 is provided. The protector 8 has its main plate surface 8a extending in the same vertical direction as the extending direction of the guide sash 7 and in the front-rear direction of the vehicle body in a direction perpendicular to the extending direction.
[0011]
As shown in FIG. 4, the rear part of the protector 8 is formed with two mounting pieces 8b, 8c with screw holes that are bent to the outside of the vehicle body, and each of the mounting pieces 8b, 8c has one bolt hole 8f, 8g is formed. The mounting pieces 8b and 8c are fastened to the inner surface of the bent portion 2a formed at the rear end of the inner panel 2 by inserting bolts (not shown) into the bolt holes 8f and 8g (FIG. 5). Further, as shown in FIG. 7, a flange piece 8 d is formed at the lower end portion of the protector 8 so as to be positioned in front of the guide sash 7 and bent toward the wind glass 4. Further, a bent piece 8e is formed at the front end portion of the protector 8 so that the tip portion protrudes from the vehicle exterior side.
[0012]
As shown in FIG. 4, a sash bracket 14 is attached to the guide sash 7 below the position where the protector 8 is disposed. The sash bracket 14 is provided with a rear bracket 14 a extending in the vehicle width direction and in the extending direction of the guide sash 7, and the rear bracket 14 a is attached to the rear end surface of the guide sash 7 by projection welding. The sash bracket 14 is bent from the end of the rear bracket 14a in the front direction of the vehicle body, and has a front bracket 14b having a surface extending at right angles to the extending direction of the guide sash 7 and extending in the extending direction of the side bracket 7. Provided. Then, a rear flange 14c that is bent toward the rear of the vehicle body is formed from the upper end of the rear bracket 14a, and a front end portion is bent toward the wind glass 4 from the front bracket 14b. The front flange 14d is formed. The rear flange 14c and the front flange 14d surround the outer surface and the rear surface of the guide sash 7.
[0013]
The relationship between the flange piece 8d of the protector 8 and the front flange 14d described above is provided with an interval in the vertical direction as shown in FIG. As a result, a crank-shaped cutoff path 15 is formed between the flange piece 8d and the front flange 14d. Further, both the flange piece 8d and the front flange 14d protrude toward the wind glass 4, but the front end portion of the front flange 14d is closer to the window glass 4. Further, as shown in FIG. 7, the front-rear position of the flange piece 8d and the front flange 14d overlap each other when viewed from above, but the flange piece 8d is located on the front side. In addition, the gap between the position of the flange piece 8d and the front flange 14d and the window 18 of the window glass 4 disposed between the inner panel 2 and the outer panel 3 shown in FIG. And the position of the lock release lever 11 are arranged on substantially the same plane so that there is no deviation in the vehicle width direction. If possible, it is preferable that they overlap as much as possible in the vertical direction. In this way, when the unlocking tool enters at a vertical or shallow inclination angle as indicated by the entry direction arrow A of the unlocking tool shown in FIG. 4, the flange piece 8d and the front flange 14d are located with respect to the unlocking tool. It can be an effective obstacle.
[0014]
A sash mounting bracket 16 is fixed to the guide sash 7 at the lower end of the guide sash 7 by welding. The sash mounting bracket 16 is provided with a mounting portion 16a facing the inner surface of the bent portion 2a formed at the rear end of the inner panel 2, and the sash mounting bracket 16 is attached by a bolt hole 16c formed in the mounting portion 16a and a bolt (not shown). Fastened to the inner panel 2. Thus, the guide sash 7 is fixed to the inner panel 2. The upper end of the guide sash 7 is inserted and fixed to the mating portion of the inner panel 2 and the outer panel 3. The latch 12 and the protector 8 of the key cylinder 6 are also fastened and fixed to the inner surface of the bent portion 2a formed on the rear end side of the inner panel 2 by bolts.
As shown in FIG. 7, the rear end portion of the window glass 4 is inserted into an opening of a guide sash 7 having a substantially U-shaped horizontal section, and a glass run 17 mounted on the inner side of the guide sash 7 is provided. And is slidably supported.
[0015]
With such a configuration, the present invention allows a third party to use a gap between the window 18 of the window glass 4 disposed between the inner panel 2 and the outer panel 3 as shown in FIG. An attempt is made to insert the unlocking tool up to the lock release lever 11 using the unlocking tool. Then, the unlocking tool first hits the flange piece 8d of the protector 8, and this flange piece 8d becomes a barrier, and the unlocking tool is prevented from being inserted further to the front end side. Further, when passing through the front end portion of the flange piece 8d, the unlocking tool reaches the front flange 14d positioned below, but the front flange 14d has the front end portion on the side surface of the wind glass 4 and the protector 8. Since the front flange 14d serves as a barrier and a crank-shaped cutoff path 15 is formed on the lower side of the flange piece 8d. The unlocking tool 11 is prevented from reaching the unlocking lever 11 so that the unlocking tool does not pass outward in the direction. In addition, neither the flange piece 8d nor the front flange 14d reaches the lock release lever 11 angularly if the unlocking tool tries to avoid it.
Further, even if the unlocking tool is to be inserted from the rear side of the guide sash 7, the rear flange 14 c of the sash bracket 14 extending rearward from the rear side portion of the guide sash 7 prevents the intrusion from reaching the lock release lever 11. Difficult to reach.
[0016]
A key cylinder 6 is disposed above the latch 12, and the key cylinder 6 and the lock release lever 11 of the latch 12 are connected to a rod 10 disposed in the vertical direction. Due to the relationship between the arrangement direction of the rod 10 and the lock release lever 11 operating in the vertical direction, it is difficult to provide the latch 12 with a protective wall extending in the horizontal direction. However, the latch 12 can be provided with a protective wall on the side (not shown). Therefore, it is difficult for the unlocking tool to enter from an oblique direction, and even if a protective wall is not provided, when the unlocking tool is inserted obliquely, the approach path becomes long and other than the vertical direction of the unlocking direction. The force is distributed to the door and the unlocking operation is difficult.
[0017]
The reason why the sash bracket 14 is attached to the guide sash 7 is as follows.
When the window glass 4 moves up and down, the window glass 4 moves relative to the guide sash 7 in the vehicle width direction. On the other hand, the upper end and the lower end of the guide sash 7 are fixed to the inner panel 2, but the guide sash 7 moves relative to the inner panel 2 in the vehicle width direction. The relative movement amount of the guide sash 7 in the vehicle width direction with respect to the inner panel 2 is at a level that does not hinder the raising and lowering of the window glass 4. In order to make this movement amount zero, it is necessary to reinforce the guide sash 7, the sash mounting bracket 16, and the inner panel 2, which increases the weight.
The amount of movement of the window glass 4 relative to the inner panel 2 in the vehicle width direction is the amount of movement of the guide sash 7 relative to the inner panel 2 in the vehicle width direction plus the amount of movement of the window glass 4 relative to the guide sash 7 in the vehicle width direction. Therefore, when the sash bracket 14 is attached to the guide sash 7, it can be brought closer to the window glass 4 to a minimum than when it is attached to the inner panel 2.
That is, the sash bracket 14 attached to the guide sash 7 can be disposed closer to the side surface of the window glass 4 than the protector 8 attached to the inner panel 2.
[0018]
Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications and changes can be made based on the technical idea of the present invention.
For example, the present invention can be applied not only to the front door 1 equipped with a key cylinder but also to other doors without a key cylinder.
