Abstract

A power closing door latch device for a motor vehicle comprises a latch engaged with a striker, a motor adapted to rotate when the latch is at a half latch position, an output member operative to rotate about a first shaft by the motor and having a slot extending radially and outwardly from the first shaft, a wire lever rotatably mounted on the first shaft and having an opening extending radially and outwardly from the first shaft, a slide member provided between the lever and the output member and having a first roller engaged with the slot and a second roller being engaged with the opening and being capable of rotating independent of the first roller, a spring for pushing the slide member in a direction in which the first roller is engaged with the slot. The wire lever is operatively connected to the latch, whereby the latch is moved by the lever to a full latch position if the output member is turned while the first roller is engaged with the slot. The device further has a canceling lever operative to slide the slide member against resilience of the spring when turned by operating an outer opening handle of a vehicle door, so as to disengage the first roller from the slot.
