DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a vehicle door lock device.

(Prior Art) Conventionally, a door lock device for a vehicle such as an automobile is provided in a rear end portion of a door body composed of a door inner panel and a door outer panel, as disclosed in Japanese Utility Model Laid-Open No. 60-126671. A lock mechanism is provided, and the lock state of the lock mechanism can be arbitrarily released by a door outer handle or a door inner handle. While the lock mechanism is provided with a synthetic resin mounting caging usually called a lock base, the lock base is fixedly installed in the rear end portion of the door body, while the lock base is fitted to the vehicle body side. A lock mechanism that engages and disengages with the engagement piece on the vehicle body side, and a lock release mechanism for arbitrarily releasing the engagement state of the vehicle body side engagement piece of the lock mechanism are assembled in a state linked to each other. There is. The lock mechanism and the unlock mechanism are fixed to the lock base via a metal plate (chassis member) usually called a set plate for mounting various mechanical parts in the rear end portion of the narrow door body. . The lock release mechanism is connected to the door outer handle and the door inner handle described above via a predetermined link member, and the lock state is arbitrarily set by the lock release operation of each of the door outer handle and the door inner handle. It is supposed to be released.

By the way, the above-mentioned door outer handle is conventionally, for example,
As shown in the figure, one end 100a of a first lever member 100 called a push lever is connected via a door outer link 101, while a door inner handle is connected to a second lever member 103 via a door inner link 102. It is connected to one end. The first lever member 100 is the lock base 1 described above.
The lock lever 104 is pivotally mounted in the center of the rear surface of the lock base 104 through a set plate 105 integrated on the rear surface of the vehicle 04, while the second lever member 103 is the lock base. A side wall portion 105a of the set plate 105, which is formed by bending an end portion of the vehicle body 104 on the vehicle compartment side to a front side of the vehicle body at a substantially right angle, is axially supported and rotatably supported in a vehicle body front-rear direction. When the door outer handle 101 is pushed downward by pulling the door outer handle, the third lever 108 on the lock release mechanism side pivots downward, and the pivotal action moves the lock release lever 109 downward. The locked state is released by pressing. In addition, the side wall portion 105a of the set plate 105 has the first
The other end 100b of the lever member 100 is loosely fitted in the vehicle compartment direction and the tip of the lever member 100 is projected by a predetermined length,
A rotation position regulating stopper hole 107 for regulating the rotation angle of the lever member 100 in the arrow D or C direction to an arbitrary range is formed. On the other hand, when the distal end of the second lever member 103 is engaged with the other end 100b side of the first lever member 100, and the pulling operation of the door inner handle is performed, the second lever member 103 is pulled. The member 103 rotates the first lever member 100 in the direction of arrow C, and pushes the third lever 108 in the same manner as when the outer door handle is pulled and the outer link 101 is pushed downward. The lock release lever 109 is pushed and rotated to release the lock with the engagement piece on the vehicle body side.

(Problems to be solved by the invention) However, in the case of the configuration of the prior art as shown in FIG. 9, the side wall portion 105a of the set plate 105 is normally shown by a phantom line in the figure. On the door inner panel 120
Are adjacent to each other, so that, for example, when the vehicle suffers a side collision, the interior side end portion 100b of the first lever member (push lever) 100 and the door inner panel 120 interfere with each other. , Between the vehicle compartment side end portion 100b of the first lever member (push lever) 100 and the door inner panel 120 so as not to operate the first lever member 100 unnecessarily. Since it is necessary to provide a space, there is a problem that the lock mechanism becomes large and the degree of freedom in design is restricted.

(Means for Solving Problems) The present invention has been made for the purpose of solving the above problems, and includes a lock base mounted in a rear end portion of a door body including a door inner panel and a door outer panel. , A set plate having a side wall portion fixed to the lock base and extending a predetermined width forward from the door inner panel side end of the lock base along the door inner panel to a vehicle body; A lock release push lever connected to the door outer handle side at a position whose one end is closer to the door outer panel side than the side wall portion of the set plate, and a rotation angle of the push lever is restricted. In the vehicle door lock device, the push lever has the other end as the door inner panel. It extends in a direction orthogonal to the side wall of the set plate and extends to the vicinity of the door outer panel surface side, and the extended end is connected to the door inner handle side, while the other pivotal portion of the set plate extends along the door inner panel. Is rotatably supported by a shaft arranged in parallel with the front-rear direction of the vehicle body as a fulcrum, and the lower part of the pivotal part projects downward, while the stopper means includes both lower parts of the pivotal part of the push lever. Is located at a predetermined distance from the push lever and is fixed to the set plate or the lock base. It is composed of first and second projecting stopper members for restricting rotation.

(Operation) That is, in the above configuration, the lower part of the pivotally-attached portion of the push lever is projected downward, and both sides of the projecting portion are brought into contact with each other at the time of rotation to regulate the bidirectional rotation position of the push lever. , A stopper structure is provided by providing a second projecting stopper member, and the range of rotation of the push lever in both directions is separated from the side surface of the door outer panel of the side wall of the set plate in the vehicle exterior direction and below the push lever. The stopper members of the first and second protrusions provided on the set plate or the lock base, which are located on both sides of the lower portion of the projecting pivot portion, are used to properly regulate the protrusions.

Therefore, the other end of the push lever extending in the direction of the side wall of the set plate may be located at least on the vehicle outer side than the side surface of the door outer panel of the side wall of the set plate. As a result, the malfunction (door opening) due to the interference with the door inner panel at the time of a side collision can be prevented, and the push lever itself can be designed to be sufficiently small and compact. In addition, since the push lever is compact, the operating space is small, and the space factor can be improved by downsizing the lock mechanism.

Moreover, in the stopper structure, since the stopper members of the protrusions are arranged on both sides of the lower portion of the push lever pivotal attachment portion as described above, the rotation locus of the push lever should be made as small as possible. In addition to the downsizing of the push lever itself, the lock mechanism itself can be made sufficiently small.

Further, according to the stopper structure as described above, it becomes easier to process parts as compared with the conventional structure in which the stopper hole is formed in the side wall portion of the set plate.
