Abstract
The structure includes a pressure receiving section configured to receive an external pressing force or a reaction force due to the pressing force. The structure further includes a frame section, a first elastic section that is connected to the pressure receiving section and to the frame section and has positive stiffness in any displacement range of the pressure receiving section, a second elastic section that is connected to the pressure receiving section and to the frame section and has negative stiffness in a predetermined displacement range of the pressure receiving section, and a deformation suppressing section that is connected to the frame section and is configured to suppress deformation of the frame section due to deformation of the second elastic section by displacement of the pressure receiving section.
