A vertical plate portion 5b extending in a direction opposite to the irradiation opening is bent and formed from an end edge portion of the horizontal plate portion 5a, and the horizontal plate portion 5a and the vertical plate portion 5b form a frame-shaped portion having a substantially L-shaped cross section. 5 is formed. The reflectors 3 and 3 are housed vertically inside the outer box 2 with the irradiation openings facing each other.

Further, each cushioning body 4 is a cushioning plate 6, 6 which is fitted to both ends of each reflecting plate 3 from the outside and which is bent in a substantially U-shaped cross section, and the insides of these cushioning plates 6, 6. And the contact plates 7 and 7 which are bent in a substantially U-shaped cross section.

Then, in a state where the reflectors 3 and 3 with the cushioning members 4 and 4 mounted therein are housed inside the outer box 2, each contact plate 7 has an outer surface of the end plate 3b of the reflector 3 and a vertical plate portion. It abuts against the edge of 5b to prevent the reflectors 3 and 3 from moving in the longitudinal direction and the vertical direction, and forms buffer spaces 8 at both ends of each reflector 3 in the longitudinal direction. Each of the reflectors 3 is protected from the impact of.

However, in the packaging apparatus 1 shown in FIGS. 9 and 10, the pair of reflecting plates 3 housed in the outer box 2 are provided.
In order to protect one end of 3, buffer plates 6, 6 and contact plate 7,
7 and 7, a buffer body 4 made of four corrugated board materials is required. Therefore, there is a problem that the packaging work becomes complicated, the number of parts constituting the cushioning body 4 increases, and it becomes difficult to improve the efficiency of physical distribution.

Then, the chassis restraints 16 and 17 are attached to the instrument main body.
The luminaire and the buffers 15 and 15 are sandwiched between the lighting unit 13 and the reflector 14 and the shock absorbers 15 and 15 are attached to both ends of the fixture body 13 and the reflector 14 by the external package 12. By being wrapped, the instrument body 13 and the reflection plate 14 are held inside the outer packaging body 12 so as not to move.

However, in the packaging device 11 shown in FIGS. 11 and 12, in order to hold the end portion of the reflection plate 14, the outer plate 15a and the inner plate 15 each made of corrugated cardboard material or the like are used.
The buffer 15 formed by adhering b and b is required, and the reflecting plate 14 is contacted and supported only by the thickness dimension of the inner plate 15b of the buffer 15. Therefore, when the reflecting plate 14 moves in the longitudinal direction, the reflecting plate 14 is easily separated from the buffer body 15, and in order to securely hold the reflecting plate 14, the thickness of the inner plate 15b is increased. It becomes necessary to set the amount, the number of materials forming the buffer 15 increases, and it is difficult to improve the efficiency of physical distribution.
