[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door lock device incorporated in a door of an automobile or the like.

[0002]

2. Description of the Related Art A door of a vehicle such as an automobile generally has a door outer (outer plate) 1 and a door inner (inner plate) 2 having a service hole 2a welded to the door outer 1, as shown in FIG. And a service hole cover 3 made of a vinyl film whose peripheral portion is bonded to the door inner 2 in order to prevent cold air leakage and moisture from entering the room from the service hole 2a, and is fixed to the door inner 2 so as to cover the entire door inner 2. Door trim (lining) 4 and glass 5 to be taken in and out between door outer 1 and door inner 2
And basically consisted of

A conventional vehicle door lock device is:
For example, as shown in FIG. 6, a lock lever 6 pivotally attached to the door inner 2 so as to be horizontally rotatable, and one end connected to the lock lever 6 and the other end between the service hole cover 3 and the door trim 4. A first locking link 7 passing therethrough, a bell crank 8 pivotally attached to the door inner 2 and having one end protruding outside the service hole cover 3 and connected to the other end of the first locking link 7; A second locking link 9 was connected to the other end, and the other end passed between the door inner 2 and the service hole cover 3 and was connected to a door lock (not shown). Reference numeral 10 denotes an inside handle which is concentrically pivotally connected to the lock lever 6 to the door inner 2 and is used to release the door lock when the door is normally opened. Are linked.

[0004] Assembling and adjustment of a link mechanism between the lock lever 6 and a door lock (not shown) have been performed as follows. As shown in FIGS. 7 and 8, first, in a state where the service hole cover 3 is not bonded to the door inner 2, the female clip 12 is fitted into a hole 2 b formed at a predetermined position of the door inner 2, and then The male crank 13 is pivotally attached to the door inner 2 by fitting the male clip 13 to the female clip 12 through the center hole of the bell crank 8 to which one end of the second locking link 9 is already connected to the other end. Further, as shown in FIG. 9, a bendable gripper 14 is fitted to one end of the bell crank 8.

Next, a service hole cover 3 provided with a slit 3a for adjusting work at a position corresponding to the bell crank 8 is adhered to the door inner 2, and then a lock lever 6 to which one end of a first locking link 7 is connected. And link 1
The inside handle 10 having one end connected thereto is attached to the door inner 2. Lastly, as shown in FIG. 9, while passing a finger through the slit 3 a of the service hole cover 3, in order to absorb the above-described error in assembling parts and errors in parts, as shown in FIG. By adjusting the positional relationship between the other end (an uneven portion for retaining is formed) and one end of the bell crank 8, the gripper 1 is adjusted.
4 is bent and its tip is gripper 1
The other end of the first locking link 7 is gripped and fixed by engaging with the 4 main body.

[0006]

However, the adjustment of the conventional vehicle door lock device must be performed after the lock lever 6 is attached, that is, after the service hole cover 3 is bonded, as described above. Is separated from the center axis of rotation of the bell crank 8, so that the service hole cover 3 must be provided with a large slit 3a,
As a result, there has been a problem that it is insufficient to prevent a cold air from leaking into the room or infiltration of moisture. Further, in order to configure around the bell crank 8, a female clip 12, a male clip 13 and a gripper 14 are required in addition to the bell crank 8 itself, so that the number of parts is increased and the assembling man-hour is increased. Also, there is a problem that the manufacturing cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a vehicle door lock device which can effectively prevent cold air from leaking into a room and infiltration of moisture, and can be manufactured at low cost. I have.

[0008]

According to the present invention, there is provided a vehicle door lock device as described above, wherein the bell crank is coaxial with one or the other of the center of rotation of the bell crank.
And two levers, one of which is a door-in
Shaft that is rotatably fitted in the hole of the nut and the center hole of this shaft
With holes with coaxial serrations, and other
The other lever is fitted into the center hole of the shaft of one lever.
Shaft with a shaft part and serrations integral with this shaft part
The serrations of these two levers are fitted to each other after their relative rotational positions are adjusted.

[0009]

According to the above construction, the point that the adjustment of the vehicle door lock device must be performed after the service hole cover is adhered is the same as the above-described conventional example, but the adjustment portion coincides with the rotation center axis of the bell crank. The service hole cover requires only a small hole. Therefore, it is possible to effectively prevent the cold air from leaking into the room and the invasion of moisture. Further, since the bell crank circumference is composed of only two levers, the number of parts is reduced and the number of assembling steps is reduced, and as a result, the manufacturing cost is reduced.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings, in which the same members as those of the above-mentioned conventional example are given the same reference numerals. FIG. 1 is a schematic view of an embodiment of a vehicle door lock device according to the present invention, FIG. 2 is an exploded perspective view around the bell crank, and FIG. 3 is a partially exploded side view around the bell crank.

The bell crank 8 has two levers 15, 16
, And one of the levers 15 is a door inner 2.
Shaft portion 1 having a center hole rotatably fitted in hole 2b
5a and a hole 15b provided with serrations coaxial with the shaft portion 15a, and one end thereof is connected to the second locking link 9. Also, the other lever 16
Shaft 1 fitted into the center hole of shaft 15a of one lever
6a and a shaft 16b provided with serrations integral with the shaft 16a, and one end thereof is connected to the first locking link 7. As shown in FIG. 4, an adjustment hole 3 b is provided at a position corresponding to the shaft of the bell crank 8 (the shaft 15 a of one lever 15) of the service hole cover 3. .

This embodiment is configured as described above, and the assembling and adjustment of the link mechanism between the lock lever 6 and a door lock (not shown) are performed as follows. As shown in FIG. 4, first, the service hole cover 3 is attached to the door inner 2.
In the hole 2b of the door inner 2 without bonding the lever 1
The lever 15 is pivotally attached to the door inner 2 by fitting the shaft 15a of the fifth member 5 with the lever.

Next, the service hole cover 3 is bonded to the door inner 2, and then the lock lever 6 to which one end of the first locking link 7 is connected and the inside handle 10 to which one end of the link 11 is connected are attached to the door inner 2. Then, the lever 16 is connected to the other end of the first locking link.
One end. Finally, in order to absorb the above-mentioned errors in assembling the parts and errors due to the dispersion of the parts, the relative rotation position of the lever 16 with respect to the lever 15 is adjusted via the hole 3b of the service hole cover 3 while the lever 16 is being adjusted.
The shaft 16a of the lever 15 is fitted into the center hole of the shaft 15a of the lever 15, and the shaft 16b is fitted into the hole 15b.

The assembly and adjustment of the link mechanism between the lock lever 6 and the door lock (not shown) in this embodiment have been described above.
, The service hole cover 3 only needs to be provided with a small hole 3b, and as a result, it is possible to effectively prevent cold air from leaking into the room and intrusion of air. Also, around the bell crank 8 are two levers 1
Since it is composed of only 5 and 16, the number of parts is reduced and the number of assembling steps is reduced, so that the manufacturing cost is reduced.
