PURPOSE: To take a large adjustment tolerance of a facial angle, to hold the adjusted facial angle without providing a fixing means, to facilitate the processing of the divided surface of a movable part and a fixed part and to secure the angle adjusting accuracy of a surface to be adjusted. CONSTITUTION: The spherical surface of a movable body 1 provided with the surface to be adjusted and the spherical surface is made to abut on the aperture end part 2b of a circular hole 2a formed on the fixed part 2. Besides, a screw 3a and a spring 4a are provided between a cover 5 fitted to the fixed part 2 and the movable body 1. By freely slidably pressing the movable body 1 to the fixed part 2 side and moving the screw 3a forwards and backwards, the angle of the surface to be adjusted is adjusted and the movable body 1 is supported on the fixed part 2 side at the same time. |
