description PROBLEM TO BE SOLVED: To enable detecting of the state of inclination at an arbitrary accuracy by guiding the body of a laser surveying device by a guide means while being moved by a fine adjustment by a screw drive means to finely adjust the position of projection. SOLUTION: Firstly, a drive screw 2 is turned to move a laser surveying apparatus body 10 to an adaptor 1 in a desired direction and an alignment work is performed so that a visible laser beam 13 vertically projected from the laser surveying apparatus body 10 matches a ground marking line 14 drawn on a floor surface 20. Then, the position 15 of the visible light laser beam 13 projected onto the ceiling 30 is marked on the ceiling 30. Then, the laser surveying apparatus body 10 can be finely moved along V-shaped grooves 3 and 4 by the drive screw 2 thereby facilitating the matching of the laser beam 13 with the marking line 14 on the floor surface 20.
