する。According to a first aspect of the present invention, a rail is provided near a top edge of a passenger doorway on a side wall of a vehicle body and extends in the width direction of the passenger doorway, and is suspended movably on the rail. An automatic door device for a vehicle comprising a sliding door and a driving means for opening and closing the sliding door in a width direction of a passenger doorway, wherein the driving means is disposed above the sliding door and the width of the passenger doorway is increased. A cylinder extending in the direction and formed of a non-magnetic material, a piston having a magnetic force slidably inserted into the cylinder, coupled to the sliding door, and slidably fitted on the cylinder. A slider that is attracted to the piston by a magnetic force through the cylinder, and a sliding door that interlocks with the piston reciprocates by supplying and discharging fluid to both airtight chambers facing the piston in the cylinder. Characterized by comprising a body intake means.

In this case, since the sliding door is suspended on the rail via the rollers, the sliding resistance can be sufficiently reduced and the driving means can be downsized. Preferably, the cylinders may extend above or below the rails in parallel. In this case, it is possible to prevent the cylinder and the slider externally fitted to the sliding door from being juxtaposed in the vehicle width direction and protruding into the vehicle compartment, so that the width of the vehicle compartment in the vehicle width direction is more reliably reduced. It can be prevented.
