Reference numeral 4 designates a case body 1 provided with a carrying hand 2,
A synthetic resin carrying case including a lid 3, wherein the case body 1 and the lid 3 are connected to each other by connecting a lower surface of each peripheral edge 1 ′, 3 ′ with a bendable hinge band 5, and a half of the inner surface center of the hinge band 5. The reinforcing ridge 6 having a circular cross section is projected, and the case main body 1 and the lid 3 are freely opened and closed by the hinge band 5. A locking device 11 is provided on each of the peripheral edges 1 ′ and 3 ′ of the case body 1 and the lid 3 on the side opposite to the connecting portion by the hinge band 5, and further, on the peripheral edge 1 ′ of the case body, a thin hinge piece 7 having a small lateral width is provided. , The inverted U-shaped handle 2 is integrally formed with the hinge piece 7,
In the center of the height 7, reinforcing protrusions 8 having a proper cross-section such as a semicircular cross-section are protruded, and the carrying hand 2 is erected and hinged by a hinge piece 7 provided with reinforcing protrusions 8. The body 1 is free to swing in a direction crossing the outer surface of the peripheral edge 1 '.

On the lower surface of the carrying hand 2, the carrying hand 2
A locking piece 9 extending in the direction of falling is formed in a protruding manner, and a resilient projection 10 for locking the above-mentioned fallen hand 2 in a non-standing state is provided at the tip of the locking piece 9. The elastic projection 10 of the locking piece 9 has a lower surface that is inclined as shown in FIG. The locking piece 9 and the elastic projection 10 can be hollow, which is open toward the inner surface of the peripheral edge 1 '.

In the locking device 11 described above, from the peripheral edge 1'of the case body 1 on the side opposite to the portion where the hinge band 5 is formed, the lid 3 is formed.
A square block block 12 having an engaging strip 13 protruding toward the upper surface of the peripheral edge 3'is formed, and a slightly taller support piece 14 is provided on the back surface of the block 12 and the support piece 14 is provided.
A hard piece 16 that is freely bent by a thin flexible elastic piece 15 formed at the upper end of the
