Angle adjustment device, support, and display device
An angle adjustment device capable of being kept at a desired angle is provided. The angle adjustment device can fix and keep the relative positions of the first base component and the second base component, and a support with a combination of the angle adjustment device and components such as a flat plate can keep the entire body in a shape opened on a plane, a folded shape, a shape kept at a desired angle, or the like. In addition, the angle adjustment device can make a bending movement in one direction, which prevents bending in a reverse direction. Therefore, it is possible to prevent an accidental bending movement of an apparatus including the angle adjustment device to prevent breakage or the like of the apparatus.
