Claims

[Claims for Utility Model Registration] A cylinder unit including a base, a mounting portion for placing an exhibit, a cylinder with one end open, and a bottomed space, the space being connected to the cylinder. and is arranged near the opening end of the space and is rotatable to the cylinder unit;
In addition, when a force is applied in a direction that presses the surface that is provided so as to be slightly movable in the axial direction of the rotating surface and that can be slid on the cylinder unit, the sliding surfaces are pressed against each other and the cylinder a rotating part that is prevented from rotating with respect to the unit; a through hole is formed in the length direction; one end is fixed to the cylinder unit; the through hole is connected to a first cylinder of the cylinder unit; an arm; a second arm having a through hole drilled in the length direction, one end of which is fixed to the rotating section, and the through hole communicating with the space of the rotating section; a first connecting the other end of the arm and the base;
a second ball joint that connects the other end of the second arm and the mounting section, and a second ball joint that connects the other end of the second arm and the mounting section; and when a pressing force is applied, the first and second
a pressing force for fixing the ball joint at an arbitrary inclination angle and pressing the sliding surface of the rotating part and the cylinder unit to fix the rotating part at an arbitrary rotating position with respect to the cylinder unit; 1. A display device comprising: means; and a handle for adjusting the pressing force on the pressing means.
