Problems solved by technology

[0005] However, in the vehicle door lock device described in Patent Document 1, since a waterproof cover is required, the number of parts increases.
In addition, although the water hole provided on the upper part of the casing can perform the desired function and expect the desired waterproof effect, it cannot guarantee that all the water that falls and adheres to the upper part of the casing will flow into the water hole, so there is concern about water intrusion. To the storage space of the case that houses the electric actuator (electrical component)

Embodiment Construction

[0018] Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 to Figure 5 A vehicle door lock device 100 based on the present invention is shown. The vehicle door lock device 100 is a device mounted on a door 201 mounted on the front right side of the vehicle, and the vehicle door lock device 100 includes a latch mechanism 10, The rod mechanism 20 , the link mechanism 30 and the electric actuator 40 are assembled in a housing 50 .

[0019] As known, the latch mechanism 10 is a device for holding the vehicle door 201 in a closed state (the door 201 is closed) relative to the vehicle body (body not shown in the figure), and therefore includes a vehicle body that can be fixed to the vehicle body. The striker (not shown) engages and disengages the locking piece 11 . The latch mechanism 10 is assembled to the vehicle door 201 in a state assembled to the casing 50 .

[0020] The lever mechanism 20 includes: an inward opening lever 2...

Abstract

The disclosed vehicle door lock device is equipped with a latch mechanism, a lever mechanism, a link mechanism and an electric actuator, which are assembled in a housing. The housing is provided with a housing body and a housing cover that are interconnected, and is arranged such that the connection surface extends vertically. A seal is formed at the connection between the housing body and the housing cover in a manner such that the seal surrounds the upper part of the housing space where the link mechanism and the electric actuator are accommodated. The seal is provided with a path, which has one open end, and inner and outer welded sections, which are contiguously formed along the passage on the inner side and the outer side of the housing. Thus, water-proofing measures (the seal) for the electric actuator (electrical part) are simply and inexpensively configured and it is easy to the condition of the seal.

Description

technical field [0001] The present invention relates to a door lock device for a vehicle. Background technique [0002] As a kind of door lock device for a vehicle, for example, the door lock device for a vehicle disclosed in the following Patent Document 1 includes a latch mechanism capable of keeping the door of the vehicle closed with respect to the vehicle body, and is connected to the housing. integrally assembled on the vehicle door; a lever mechanism assembled on the housing and driven by operating a door handle provided on the vehicle door; a linkage mechanism clamped on the lock in the housing between the piece mechanism and the lever mechanism, and can be switched to an unlocked state in which the operation force transmission from the lever mechanism to the lock plate mechanism is valid, or a locked state in which the operation force transmission is invalid; and An actuator (electrical component) is assembled in the housing and switches the link mechanism to the u...
