Abstract
A hinge structure includes a rotatable plate member, a frame member, a spring member that connects the rotatable plate member with the frame member at each of two opposite positions along a rotation axis. The spring member includes a first axial section, a second axial section. An end of the first axial section is connected to the frame member, and an end of the second axial section is connected to the rotatable plate member. The spring member includes a first zigzag section and a second zigzag section formed on opposite sides with respect to the rotation axis, each of the first and second zigzag sections including parallel portions which are parallel with each other and with the rotation axis and bent portions each connecting adjacent parallel portions. A predetermined gap between the first and second axial section is smaller than a length of the parallel portions.
