  • Patent number: 9932761
    Abstract: A vehicular door device in which an inner handle is connected to a latch mechanism with a wire so as to be capable of being linked, and in which a latch release restriction device that disables and restricts a link between the inner handle and the latch is provided in an operation transmission path ranging from the inner handle to the latch with the wire in between. A release motor that actuates the latch in an engagement releasing direction is provided, the release motor being linked to the latch without having the wire between itself and the latch.
