  However, in the marker lamp mounting depth adjusting device according to the above-mentioned Japanese Patent Application Laid-Open No. 2003-336230, the adjustment ring (D) to which the lamp (F) is mounted and the base (C) embedded in the road surface The separation distance (attachment depth of the lamp body) is configured to be adjusted up and down by screwing forward and backward operation of the first to third members (1), (2), and (3) interposed between the upper and lower sides, There are the following problems.

  That is, there is no female screw on the inner peripheral surface of the intermediate portion of the cylindrical third member (3), and partial female screws (3a) (3b) respectively carved only on the lower inner peripheral surface and the upper inner peripheral surface thereof. And the male screws (1b) and (2b) respectively carved correspondingly on the outer peripheral surfaces of the flat ring-shaped first and second members (1) and (2) are merely screwed and fastened. The adjustment amount of the lamp body mounting depth is still small, and it is easy to cause a situation that cannot be adapted to the actual road surface.

  If it does so, it cannot use the attachment depth adjustment apparatus for beacon lights estimated and produced from the design value, but it is necessary to produce this specially as a construction site match, resulting in a cost increase and a delay in delivery time.
