Carrier {Carrier}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a conveying apparatus, and more particularly, to a conveying apparatus capable of conveying a conveying object in a narrow space by fastening a conveying object to the inside or the other side.

Workers should place their bulky and heavy objects in a narrow space such as a ship's cabin. At this time, the heavy object may be overturned, resulting in a safety accident of the worker, and the worker may place the heavy object directly, which increases the working time.
