で、警光灯の内部構造の変更を容易に行える。Effects of the Invention As described above, the warning light according to the present invention is constructed by slidingly inserting the support plate in the form of a strip to which internal equipment is attached into the transparent globe body in the form of a tube. Since the interior equipment can be stored in the interior, it is necessary to configure the warning light, as in the past, with a box-shaped base for supporting the interior equipment and a transparent globe installed on the base. The number of parts for the entire warning light can be reduced, the weight of the warning light can be reduced, and costs can be reduced at the same time. In addition, the warning light according to the present invention is
Assembling work is easy, and the internal equipment inside the transparent glove body can be easily pulled out from inside the transparent glove body, so maintenance work can also be easily performed. In addition, the present invention has four guide grooves for slidingly inserting the support plate into the transparent glove body at the bottom, top, front, and rear of the inner peripheral surface of the transparent glove body.
When the support plate is inserted into the first guide groove located at the bottom, the internal equipment will face upward,
When the support plate is inserted into the second guide groove located at the top, the internal equipment faces downward; when the support plate is inserted into the second guide groove located at the top, the internal equipment faces downward, and the support plate When the support plate is inserted into the third guide groove located at the front, the interior equipment faces rearward, and when the support plate is inserted into the fourth guide groove located at the rear, the interior equipment faces forward. , in a warning light made of the same component, the orientation of the internal equipment housed inside the transparent globe body is 4.
It can be set in either direction. Furthermore, according to the present invention, the internal structure of the warning light can be easily changed by simply changing the support plate to which the interior equipment is attached.
