PURPOSE:To heighten airtightness at the time when a door is closed by providing a door drawing-in device that is engaged with a pin in the door rear upper part, to the peripheral part of an entrance in the door rear upper part of the door, and by providing a drawing-in cam that has both a first claw which is abutted on the pin for starting a drawing-in cylinder in the final stage the door is closed, and a second claw for drawing in the pin toward the inside of a vehicle. CONSTITUTION:In an upper drawing-in device 11, a rod 61a is extended in the door- closed condition. In the final stage a door 3 is closed, a pin 63 is curvedly moved in the direction of the arrow f. When the pin 63 abuts on the first claw 57a of a drawing-in cam 57, the drawing-in cam 57 is turned in the counterclockwise direction, and also a timing cam 58 on the same axis is turned. Accordingly, a lever 59a is oscillated in the clockwise direction, and a changeover valve 59 is changed over, and pressurized air is supplied to the rod-side chamber of a drawing-in cylinder 61. The drawing-in lever 57 is turned from the position shown by the two-dot chain line to the position shown by the continuous line, and a second claw 57b strongly draws in the pin 63 toward the vehicle body 1 side, and also the door rear upper part is closed in the vehicle body 1. In other words, the door 3 is supported by the upper and lower parts both on the door front side and on the door rear side, or at four points. |
