Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door lock device in which a seal member for preventing rainwater from entering a body accommodating a rotating member is attached to an outer surface of the body.

[0002]

2. Description of the Related Art A conventional door lock device for an automobile has a structure in which rainwater intrudes into the inside of a body which accommodates a latch which can be engaged with and disengaged from a striker and a rotating member such as a locking plate which can be engaged with and disengaged from the latch. A seal member formed of rubber or the like for preventing the above is attached to the body with an adhesive or the like.

A stopper, which is formed of rubber or the like and is capable of contacting the latch and the locking plate, is provided inside the body in order to reduce the impact sound when the latch and the locking plate are stopped at a predetermined stop position. It is provided at a position (for example, see Japanese Utility Model Laid-Open No. 61-187871).

[0004]

However, in the conventional door lock device as described above, since each stopper and the seal member have to be attached to the body, the number of parts increases and the attaching work becomes complicated. Therefore, the cost of the door lock device may increase.

In view of the above problems of the prior art, the present invention simplifies the work of attaching the seal member having a waterproof effect and the stopper portion for mitigating the hitting sound, and consequently the door lock device. An object of the present invention is to provide an automobile door lock device that enables cost reduction.

[0006]

According to the present invention, the above-mentioned problem is solved as follows. (1) In a vehicle door lock device in which a turning member is rotatably housed inside a body having an entrance groove into which a striker enters, and an elastic seal member is attached to an outer surface of the body near the entrance groove, A stopper portion, which is fitted to a holding portion formed inside the body and stops the rotating member at a predetermined stop position when the rotating member abuts, is integrally provided on the seal member.

(2) In the above item (1), the rotating member is a latch which can be engaged with and disengaged from the striker, and a locking plate which restrains the rotation of the latch by engaging with the latch.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to the accompanying drawings. (1) is fixed in a door panel (A) pivotally supported in the vehicle body so as to be openable and closable as shown in FIG. 4, and is engaged with a striker fixed to the vehicle body side to close the door. In the restraining door lock device, the resin body (2) formed of a hard synthetic resin material and the resin body (2) so as to close the concave housing portion (2a) formed in the resin body (2). A metal plate cover plate (3) fixed to the front side and a metal plate base plate (4) fixed to the back side of the resin body (2) are provided.

A notch groove (3a) that overlaps with the entrance groove (2b) of the body (2) is cut out at approximately the center of the cover plate (3). The base plate (4) is bent into an L-shape, and has various doors such as a door handle for opening the door, a key cylinder for locking and unlocking the door lock device, and various levers connected to various operating systems such as a lock knob. It is rotatably arranged. Since these various levers are not directly related to the present invention, their explanations are omitted.

In the accommodating portion (2a) of the resin body (1), a shaft (6) is pivotally attached to a shaft hole (2f) formed above the entrance groove (2b), and normally urged by a spring. Then, the latch which stops at the release position shown by the two-dot chain line in FIG. 2 and engages with the striker that has entered the entry groove (2b) by the closing operation of the door, rotates to the closed position shown by the solid line ( 5)
And the shaft (7) in the shaft hole (2g) formed below the entrance groove (2b).
Is normally pivoted by a spring (9), and is normally urged clockwise by a spring (9), and is engaged with one of the first and second claws (5a) and (5b) of the latch (5). Locking plate that locks the door to the closed position and locks the door to the closed position
(6) and are stored.

The latch (5) is almost entirely covered with a resin material, and a tongue (5c) which is elastically deformable in the plate thickness direction and prevents rattling of the latch (5) is formed on the outer periphery thereof. It is integrally formed of a resin material.

In the resin body (2), as shown in FIG.
A concave entry groove that guides the striker when the door is closed
(2b) and the upper and lower portions near the entrance (2c) of the entrance groove (2b), and the cylindrical upper and lower holding portions (2e) at positions corresponding to the stop positions of the latch (5) and the locking plate (6). Are formed. The holding part (2e) on the upper side is the claw part (5) of the latch (5).
The side facing b) is open, and the lower holding part (2e) is open on the side facing the locking plate (6). The upper and lower holding parts (2e) are connected to the resin body (2) through the communication hole (2d).
Leading to the outer surface of.

As shown in FIG. 6, (9) is a seal member which is U-shaped in side view and which is formed of an elastic member of soft rubber.
As shown in FIG. 4, it is attached to the outer surface of the resin body (2) on the entrance (2c) side of the entrance groove (2b) so as to be sandwiched between the resin body (2) and the door panel (A). Seal part (9a)
And each arm part extended from both ends of the seal part (9a)
A cylindrical stopper portion (9c) (9d) provided at the tip of (9b) and fitted to the upper and lower holding portions (2e) is integrally formed.

On the back side of the sealing portion (9a) facing the resin body (2), the sealing portion (9a) is engaged with a hole (not shown) formed in the resin body (2). An engaging portion (9e) for fixing to (2) is formed to project.

The seal portion (9a) is fixed to the outer surface of the resin body (1) to prevent rainwater from entering the inside of the resin body (1). When the latch (5) moves to the stop position which is the release position, the upper stopper portion (9c) abuts the side edge of the claw portion (5b) to mitigate the tapping sound at the time of stop, and the lower side When the locking plate (6) is brought to the stop position at the engaging position where the locking plate (6) engages with the claw portion of the latch (5), the stopper part (9d) of the stopper abuts the tapping sound at the time of stop. To do.

The seal member (9) engages the engaging portion (9e) with the hole of the resin body (2), and the upper and lower arm portions (9).
b) into the insertion part (2d), and the upper and lower stopper parts (9c) (9
After fitting d) to the upper and lower holding parts (2e) (2e) and temporarily fixing to the resin body, fix the cover plate (3) so as to cover the housing part (2a) of the resin body (2). As a result, the upper and lower stoppers (9c) (9d) and arm (9b) are
It is sandwiched between (1) and the carver plate (3) and is securely fixed to the storage section (2a). Therefore, the seal member (9) can be easily and surely attached to the resin body (1) without using an adhesive or the like.

[0017]

According to the present invention, the following effects can be obtained. The number of parts is reduced by integrally forming a seal part that prevents rainwater from entering the body and a stopper part that mitigates the tapping sound when the rotating member stops at the stop position. Therefore, it is possible to simplify the mounting work of the seal member and reduce the cost.
