PROBLEM TO BE SOLVED: To suppress the mounting height of a case for a vehicular beacon head in horizontal mounting specifications capable of corresponding to an incline and reduce costs. SOLUTION: This case attaches a flat plate to one side of the side edge orthogonal in the light receiving direction of a lower case 2 as a seating 20 free of rotation and detachably with a bolt 17 alone, and at the point midway in the rotational range, it is made securable tight to a case 10 with the bolt 17. In the case where it is mounted on an incline surface 52', the case 10 is angled so as to make it be horizontalized. Since a mounting position of the flat plate 20 is situated in a 'corner' at the base side in the flank of the case 10, height from the incline on a case surface becomes as far as merely almost height of the case 10, the height from the incline surface 52' is thus checked as compared with the case where such a seating 21 as a small structure in the past is attached to a case bottom cross direction center. Moreover, as the seating 21 is comprised of one flat plate 20 and one bolt 17, material cost and time-labor in the manufacturing process both are inexpensively reducible.
