Definitions

  • the present invention relates to a plug door device.
  • Patent Literature 1 discloses a plug door device including a door leaf, a rotatable pillar connected to the door leaf and being rotatable, a support oriented in a direction in which the door leaf is slidable, a first locking mechanism provided on a top portion of the door leaf, and a second locking mechanism provided on a bottom portion of the door leaf.
  • the door leaf becomes slidable by moving the support and the rotatable pillar with a driving force from a motor or other drive source.
  • Another known plug door device includes a stationary base fixedly attached to a vehicle body, a slidable base having a door attached thereto and being slidable in a width direction of the vehicle relative to the stationary base when acted upon by a driving force from a drive source, and a lock mechanism configured to lock the door.
  • the lock mechanism includes a locking roller rotatable around an axis extending in a height direction of the vehicle. When the door is fully closed and the lock mechanism is in a locked state, an external force is applied to move the locking roller, so that the locking roller touches a block of a door hunger. In this manner, the door is locked by the locking roller when fully closed.
  • a pressure difference may occur between the inside and the outside of the vehicle, creating a negative pressure outside the vehicle. If such is the case, the slidable base may rotate around the locking roller depending on where the locking roller is placed.
  • Patent Literature 1 Japanese Patent Application Publication No. 2016-538171

  • the slidable base 4 is positioned below the stationary base 3.
  • the slidable base 4 extends in the front-rear direction along the upper edge of the doorway 15.
