As shown in FIG. 5, the instrument body 15 has a pole receiving portion mounting hole 27 at a position corresponding to the pole receiving portion 14. The pole receiving portion mounting hole 27 has an inner diameter that is slightly larger than the outer diameter of the inclined instrument body mounting portion 22 of the pole receiving portion 14.
The pole receiver 14 is fixed to the instrument body 15 by joining means such as welding after the inclined instrument body attachment part 22 is inserted into the pole receiver attachment hole 27 of the instrument body 15.

The fall prevention metal fitting 18 has a main body 28 fixed to the inner surface of the pole receiving portion 14 by a joining means such as welding, and has a flange portion 29 bent in an L shape at the upper portion of the main body 28.
In the fall prevention metal fitting 18, the flange portion 29 is bent or bent at a right angle in a direction intersecting the axial direction of the pole 13.
The fall prevention metal fitting 18 is inserted into the pole receiving portion mounting hole 27 of the instrument body 15 so that the flange portion 29 is arranged in parallel to the mounting surface of the solar cell 16, and the flange portion 29 is attached to the pole receiving portion. It protrudes outward from the hole 27.

At this time, the bending direction of the flange portion 29 is the axial direction of the pole 13, that is, the direction orthogonal to the inclination direction of the instrument body 15, but is not limited thereto, and is along the inclination direction of the instrument body 15. It may be.
Moreover, it is preferable that a pair of the fall prevention metal fittings 18 is provided at opposing positions along the radial direction of the pole 13 in the instrument body mounting portion 22 of the pole receiving portion 14. However, the number of the fall prevention metal fitting 18 may be one.

In the state where the instrument main body attachment part 22 of the pole receiver 14 is fixed to the pole receiver attachment hole 27 of the instrument main body 15, the fall prevention metal fitting 18 has a pair of flange parts 29 determined in advance from the upper surface of the instrument main body 15. The distance (see FIG. 7) is set apart by L1.
The fall prevention metal fitting 18 has corrosion resistance sufficiently longer than the time when the pole 13, the pole receiving portion 14, and the instrument main body 15 are corroded or fatigued, and the instrument main body 15 in which the solar cell 16 and the power supply device 17 are accommodated. The strength is sufficient to withstand the weight of

Next, the construction of the lighting fixture 10 will be described.
In the assembly factory, the solar battery 16 and the power supply device 17 are attached to the fixture body 15, and the fixture body mounting portion 22 of the pole receiving portion 14 to which the pair of fall-preventing metal fittings 18 is fixed is the pole receiving portion mounting hole 27 of the fixture body 15. Fixed by welding or the like.
Next, the pole receiving portion 14 is screwed after being mounted on the upper end portion of the pole 13, and the power supply device 17 is electrically connected to the light emitting portion 12.

Then, the anchor 19 of the pole 13 is installed by being buried in the ground 90 at a predetermined place.
Thus, since the lighting fixture 10 does not perform the operation | work which locks a wire to the latching | locking part inside a pole like the past at the time of construction, it can make assembly workability | operativity at the time of construction favorable.

Next, the operation of the fall prevention fitting 18 will be described.
As shown in FIG. 6 and FIG. 7, normally, the flange portion 29 of the fall prevention metal fitting 18 is parallel to the mounting surface of the solar cell 16 at a position away from the upper surface of the instrument main body 15 by a predetermined distance L1. Has been placed.

As shown in FIG. 8 and FIG. 9, corrosion and metal fatigue occur at the welded portion between the instrument main body attachment portion 22 of the pole receiver 14 and the pole receiver attachment hole 27 of the instrument main body 15 due to aging.
In this state, when a wind and rain such as a typhoon accompanies, the welded portion between the pole receiving portion mounting hole 27 of the instrument main body 15 and the instrument main body mounting portion 22 of the pole receiving portion 14 may be destroyed.

At this time, when the instrument main body 15 is inclined in the direction of the arrow shown in FIG. 8, the flange 29 of the fall prevention metal fitting 18 is engaged with the outside of the pole receiving part mounting hole 27 of the instrument main body 15 (FIG. 9).
Therefore, even if the instrument main body 15 is inclined in the direction of the arrow shown in FIG. 8, the hook body 29 of the fall prevention metal fitting 18 is engaged with the outside of the pole receiving portion mounting hole 27 of the instrument main body 15, thereby Is prevented from falling.

On the other hand, when the instrument main body 15 is inclined in the direction opposite to the arrow direction shown in FIG. 8, similarly, the flange 29 of the fall prevention metal fitting 18 is placed outside the pole receiving portion mounting hole 27 of the instrument main body 15. Engaged.
Therefore, even if the instrument main body 15 is inclined in the direction opposite to the arrow direction shown in FIG. 8, the collar part 29 of the fall prevention metal fitting 18 is engaged with the outside of the pole receiving part mounting hole 27 of the instrument main body 15. The instrument body 15 is prevented from falling.

As described above, according to the solar power generation device 11 of the embodiment according to the present invention described above, even if the welded portion between the instrument main body 15 and the pole receiving portion 14 is broken and the instrument main body 15 is inclined, the fall prevention metal fitting 18 The flange portion 29 is engaged with the outside of the pole receiving portion mounting hole 27 of the instrument main body 15.
Therefore, according to the solar power generation device 11, the fitting main body 15 is prevented from falling by engaging the flange portion 29 of the fall prevention metal fitting 18 with the outside of the pole receiving portion mounting hole 27 of the tool main body 15.
Moreover, according to the solar power generation device 11, since the operation | work which locks a wire to the latching | locking part inside a pole is not performed at the time of construction like before, the assembly workability | operativity at the time of construction can be made favorable. .

  According to the solar power generation device 11, since the collar portion 29 of the fall-preventing metal fitting 18 is bent or bent at a right angle in a direction intersecting the axial direction of the pole 13, it can be easily manufactured, and the instrument body 15 Even if the weight is large, the instrument body 15 can be securely held.

  According to the lighting fixture 10, the light emission part 12 can be lighted with the electric power given from the power supply device 17 of the solar power generation device 11, the assembly workability | operativity at the time of construction is made favorable, and the fixture main body 15 of the solar power generation device 11 falls. Can be prevented.
