Claims

[Scope of claim for utility model registration] Two pulleys installed in the lintel above the entrance of the vehicle, a transmission band wound around the two pulleys,
A vehicle door closure comprising two left and right doors connected to the upper and lower parts of the transmission band via connecting members, respectively, and a drive source connected to one of the two doors to drive the door in the opening/closing direction. In a double-opening mechanism of a machine, a lever shaft provided between an upper part and a lower part of the transmission band, a lever provided to be biased to rotate in one direction by the lever shaft, and a lever provided immediately before the door is in a fully closed position. a pressing portion provided on a connecting member of the door connected to the drive source so as to rotate the lever against the rotation biasing force of the lever; and a pressing portion provided on a connecting member of the door connected to the drive source so as to rotate the lever against the rotation biasing force of the lever, and another pressing portion provided on the connecting member of the door connected to the driving source so as to be located on the closing direction side from the lever when the door is fully closed. A double-opening mechanism for a door closing machine for a vehicle, characterized in that it is equipped with a safety lock device consisting of a locking part provided on a connecting member of a door.
