PURPOSE:To ensure the safety and maintenance by forming a recess at the top of a base table, forming projection detaining with this recess at the lower part of a support, wherein the location of the projection in deteining shall be adjustable, and making adjustment of the light projection angle of a beacon light body between the base table and the support. CONSTITUTION:A base table A is mounted on the ground, and a support B is fitted to this base table A. The base member of a beacon light body which has undergone adjustment of the optical system previously, is mounted to the support B. After mounting in this arrangement, locational adjustment for adjustment of the light projection angle is made between the base table A and support B. This adjustment of light projection angle is made in such procedures that first a screw 20 is inserted in a long hole 4 in the base table A from inside the support B through a through hole 11 and moved along the long hole 4 as angle adjusting work, and then fastening is made at the desired angle using a wind nut 22 with a washer 21 interposed. This ensures that the works are performs simply and quickly. |
