<p>The present invention relates to a backpack including a backpack body having a space for receiving objects. In the backpack, a back plate made of a synthetic resin is disposed in a space defined within a back plate part, which is the area of the backpack body facing the back of wearer. Also, two shape supports, formed into a shape corresponding to that of the spine of the human body, are vertically disposed on the left and right sides of the synthetic-resin back plate. Two back supports are horizontally divided and disposed outside the back plate part. A coupling bolt protruding backward from the back surface of the back support passes through the back plate part, the back plate disposed within the back plate part, and the shape support, and is coupled and fixed by a coupling nut. In the synthetic-resin back plate, a horizontal contact part is vertically disposed at the center of a position on which the two shape supports are disposed to reduce the bending stiffness in the horizontal direction of the synthetic-resin back plate such that the synthetic-resin back plate is horizontally bent and folded so as to enable the back supports to be closely attached to the wearer.</p> |
