PURPOSE: To finely adjust the inclination of a door in all directions by storing a spherical internal easing fastened to the tip of an arm in a cavity of an external casing rotatably connected to a fastening plate and providing a clamp collar. CONSTITUTION: An external easing 11 is connected to a fastening plate 3 fitted to a door 4 to be freely rotated by a pivot 5. A substantially spherical internal caseing 21 fastened to the tip of an arm 2 is stored in a cavity having a semispherical bottom of an external casing 11. The pivot 5 is passed through a cylindrical hole of the internal casing 21. A clamp collar 13 is passed through the arm 2 and slidably fitted to the external casing 11, and pressure is applied to the internal casing. The inclination of the door can be finely adjusted in all directions by a clearance gap between the internal casing and the pivot and a clearance gap between the arm and the clamp collar. |
