Abstract: A slide door is suitable for use in a vehicle slide door of a type where a window glass is lowered and a window is opened. This slide door includes an intermediate stopper mechanism. The intermediate stopper mechanism includes an intermediate striker disposed at a vehicle side, a first pole rotatably disposed at a slide door side and detachably engaged with the intermediate striker, a first latch which is a latch to engage with the first pole rotated to a position where it cannot abut on the intermediate striker and to restrain the first pole to that position, and which releases restraint of the first pole when a window glass of the slide door is opened to a predetermined position. By this structure, switching of the intermediate stopper mechanism can be carried out without fail.
