<p>A vehicle door lock device includes a latch mechanism, a lever mechanism, a link mechanism, and an electric actuator, which are assembled to a housing. The housing includes a housing body and a housing cover joined to each other, and is arranged so that a joining surface between the housing body and the housing cover extends along an up-and-down direction. A sealing portion is formed along a joining portion between the housing body and the housing cover so as to surround an upper part of an inner space of the housing accommodating the link mechanism and the electric actuator. The sealing portion includes a communication path including one open end, and an inner welded portion and an outer welded portion formed continuously along the communication path on an inner side of the housing and an outer side of the housing with respect to the communication path, respectively. Accordingly, it is possible to achieve waterproofing measures (sealing portion) for the electric actuator (electrical part) simply at low cost, and to easily determine whether or not the sealing portion maintains satisfactory sealing properties (airtightness and fluid-tightness).</p> |
