FIG. 7 is a perspective view showing the configuration of the clamp unit 26.
As shown in the figure, the clamp unit 26 includes the plate-shaped flange portion 30 described above that extends from the outer peripheral surface 29 </ b> C of the cylindrical portion 29. The flange portion 30 is a member that is bolted to the clamp unit fixing portion 50. Specifically, as shown in FIG. 5, the clamp unit fixing portion 50 includes a pair of left and right unit fixing columns 52 extending substantially horizontally from the rear surface 21 </ b> A of the base case body 20 to the rear (on the one end 11 </ b> A side). Yes. The upper surface 52A and the lower surface 52B of the unit fixing column 52 have a flat shape, and are fastened to each other with a bolt or the like while the plate surface of the flange portion 30 is received by the surface.

Further, as shown in FIG. 7, the flange portion 30 of the clamp unit 26 includes a plate-like pole-type support rod portion 35 and a plate-shaped arm-type support rod portion 36. The pole-type support rod portion 35 is used for fixing to the unit fixing column 52 when attached to the pole-type support column 4, and the arm-type support rod support portion 36 is used when attached to the arm-type support column 5. Used for fixing to the unit fixing column 52.
Specifically, the pole-type support rod flange 35 is provided such that the plate surface 35 </ b> A which is the front and back (upper and lower) surfaces is substantially parallel to the orthogonal direction Ma of the major axis M of the cylindrical portion 29. Accordingly, the cylindrical portion 29 is formed by overlapping and fastening the surfaces of the plate surface 35A of the pole-type support rod portion 35 and the upper surface 52A or the lower surface 52B (upper surface 52A in the illustrated example) of the unit fixing column 52. It is fixed to the clamp unit fixing portion 50 in a state of standing up and down, and can be used as the pole-type clamp unit 26.

  On the other hand, the arm-type support rod portion 36 is provided such that the plate surface 36 </ b> A is substantially parallel to the direction of the long axis M of the cylindrical portion 29. Therefore, the long axis M of the cylindrical portion 29 is extended from the one end 11A by superimposing and fastening both the plate surface 36A of the arm-type support rod portion 36 and the upper surface 52A or the lower surface 52B of the unit fixing column 52. It will be fixed to the clamp unit fixing part 50 in a state lying substantially parallel to the other end 11B, and can be used as the clamp unit 26 for the arm type.

  In the present embodiment, the plate surface 35 </ b> A of the pole-type support rod portion 35 is not completely parallel to the orthogonal direction Ma of the long axis M of the cylindrical portion 29, but according to the inclination angle of the instrument body 10 with respect to the horizontal plane. It is inclined from the orthogonal direction Ma by an angle. Similarly, the plate surface 36A of the arm-type support rod flange 36 is inclined with respect to the direction of the long axis M of the cylindrical portion 29 by an angle corresponding to the inclination angle.

Here, as shown in FIG. 7, the pole-type columnar flange 35 and the arm-type columnar flange 36 are provided on the cylindrical portion 29 so that the plate surfaces 35A and 36B are substantially orthogonal to each other. It is difficult to mold the clamp unit 26 with aluminum die casting or the like.
Therefore, in this embodiment, as shown in FIG. 7, a clamp unit piece 26 </ b> A having a shape in which the clamp unit 26 is vertically divided into two at the middle of the plate thickness of the pole-type support rod portion 35 is configured. The clamp unit 26 is assembled by connecting the clamp unit pieces 26A.
In the clamp unit piece 26A, the cylindrical portion 29 and the arm are formed on one surface of a plate-shaped pole-type support rod piece 37 obtained by dividing the thickness of the pole-type support rod portion 35 in the middle. A cylindrical part piece 39 corresponding to a part obtained by dividing the mold post support part 36 vertically into two parts and an arm type post support part 38 are erected, which facilitates molding.

In this clamp unit piece 26A, as shown in FIG. 7, the long axis passing through the center O of the cylindrical piece 39 (cylindrical portion 29) is provided with arm-type support rod pieces 38 on the left and right sides of the cylindrical piece 39. It is arranged at a position shifted by a distance α, not at a position where M is sandwiched therebetween.
At the time of assembling the clamp unit 26, the pair of upper and lower clamp unit pieces 26A is not in a posture in which the arm-type support rod pieces 38 are arranged vertically in a straight line, but as shown in FIG. The pieces 38 are connected in such a posture that the long axis M is sandwiched therebetween. As a result, when the clamp unit 26 is viewed from the side, the arm-type strut flange 36 has a stepped shape in the direction of the long axis M. That is, since the arm-type strut flanges 38 of the arm-type strut flange 36 are arranged in steps, when the arm-type strut flange 36 is used for fixing, as shown in FIG. The upper surface of the plate surface of the arm-type support rod piece 38 on the one end 11A side is in contact with the lower surface 52B of the unit fixing column 52, and the plate of the arm-type support rod piece 38 on the upper stage side (the other end 11B side). Of the surfaces, the upper surface comes into contact with the upper surface 52A of the unit fixing column 52.
Thereby, since the load is applied to the arm-type support rod portion 36 in the upside down direction on the one end 11A side and the other end 11B side, the strength against the load in the vertical direction K is increased, and The load bearing performance is improved.

As described above, according to the clamp unit 26 of the present embodiment, the plate surface extends from the outer peripheral surface 29C of the cylindrical tube portion 29 inserted into the distal end portion 3 of the support columns 4 and 5 so that the plate surface is a tool. An arm-type support rod flange 36 whose plate surface 36A extends along the direction of the long axis M of the cylindrical portion 29 and a plate surface 35A of the cylindrical portion 29 are joined to the flange portion 30 that is coupled in surface contact with the main body 10. A pole-type strut flange 35 that is substantially orthogonal to the direction of the long axis M is provided.
According to this configuration, the direction of the long axis M of the cylindrical portion 29 is changed by replacing the collar portion 30 that is brought into surface contact with the instrument main body 10 between the arm-type support rod portion 36 and the pole-type support rod portion 35. It can be changed by 90 degrees. Accordingly, in the state where the cylindrical portion 29 is stood to receive the tip portion 3 of the pole-type support column 4, the instrument body 10 is provided, or in the state where the cylindrical portion 29 is set sideways to receive the tip portion 3 of the arm-type support column 5. It can be provided on the instrument main body 10 and can be shared by these pole type and arm type columns.

Further, according to the present embodiment, the clamp unit 26 is divided into two in the direction of the long axis M of the cylindrical portion 29 so as to divide the plate thickness of the pole-type support rod portion 35.
As a result, a cylindrical piece 39 obtained by dividing the cylindrical portion 29 and the arm-type strut flange 36 on the surface of the plate-shaped pole strut flange 37 formed by dividing the pole-shaped strut flange 35, In addition, since the arm-type support rod piece 38 is erected, molding becomes easy.

  Further, according to the present embodiment, the arm-type strut flanges 38 are arranged in steps so that the arm-type strut flanges 36 have a step in the direction of the long axis M, and the arm-type strut flanges 38 on the upper side are arranged. The lower surface of the plate surface and the upper surface of the plate surface of the arm-type support rod piece 38 on the lower side were brought into surface contact with the instrument body 10 and fastened. Thereby, since the load is applied to the arm-type support rod part 36 in the opposite direction at the one end side and the other end side of the long axis M, the strength against the load in the vertical direction K is increased, and The load bearing performance is improved.

The above-described embodiment is merely an example of one aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.
For example, the present invention is not limited to a road lamp, and can be applied to an arbitrary lighting fixture such as a street lamp, as long as it is a lighting fixture that supports a fixture main body supported by a tip end portion of a column.
