  • the opening / closing operation of the movable rails 15 and 16 can be performed manually by an operator. However, in some cases, a power source such as a motor is separately used, and the movable rails 15 and 16 are replaced by human power. It can also be opened and closed.
  • the configuration of the locking means 28 for connecting the inner end portions of the two movable rails 15 and 16 closed at the connecting action position is not limited to that of the above embodiment.
  • a long pin is used as the locking pin 31, and a hole is formed on the floor surface side where the lower end of the locking pin 31 inserted into the through holes 29a, 30a of the upper and lower plate members 29, 30 is inserted.
  • the position of the inner ends can be fixed to the floor surface.
  • the lock means 28 that switches to the locked state by human operation
  • the automatic lock that automatically engages when both the movable rails 15 and 16 are closed to the connecting action position (closed limit position) in series. It can also be a means.
  • the unlocking operation of the locking means 28 is not limited to manual operation. When specific conditions are met, such as a human switch operation in a situation where safety is confirmed, an appropriate operation such as a cylinder unit or a solenoid is performed.
  • the lock means can be automatically unlocked by a simple actuator. When providing the locking means having such an automatic unlocking function, it is desirable that the two movable rails 15 and 16 are opened by power in a predetermined order as described above.
  • the travel route structure of the transport traveling body of the present invention is a layout in which a transverse passage is provided so as to intersect the travel route of the transport traveling body traveling on a guide rail laid on the floor surface. It can be used as a means for safely passing other vehicles.
