Abstract: A hinge structure includes: a lower member which is to be attached to a container; an upper member which is to be attached to a lid; a rotary shaft connecting the lower member and the upper member to each other; and a link mechanism connecting the lower member and the upper member to each other at a position different from the position of the rotary shaft. The link mechanism includes a plurality of links pivotably connected to each other, and a spring mechanism of a torsion coil type configured to give spring force to the upper member in a direction in which the lid is opened.
