<p>PURPOSE: To prevent a carrying article from being taken away together with a carrying device by arranging unfolding members so as to be unfoldable outward from side parts of a box body to house the carrying article, and starting unfolding operation of the unfolding members by a starting device. CONSTITUTION: In a theft preventive device 18, horizontal parts of unfolding members 18a are inserted into holders 18b arranged in both side parts of a stand part 14 of a carriage 10, and respective vertical parts of the two unfolding members are locked by a locking device 26. Coil springs 18d as energizing means for the unfolding members 18a are arranged in the holders 18b, and the vertical parts of the unfolding members 18a are energized outside from side parts of the carriage 10. The locking device 26 releases a locking action of the unfolding members 18a to a frame 12 when a receiver 20 receives an emergency signal from a transmitter of a carrying member. As a result, the unfolding members 18a unfold outward from the side parts of the carriage 10 by an energizing action of the coil springs 18d, and collide with surrounding things, so that a box body is hardly taken away.</p> |
