As shown in FIGS. 3 and 4, the bottom plate 17a is formed with an opening 71 through which a cable or the like (see FIG. 2) wired between the transmission mechanism 11 and the power feeding unit 2 passes.
The opening 71 can have a planar view shape that is rotationally symmetric about the axis C <b> 1 along the connecting direction of the transmission unit 1 and the power feeding unit 2 (the vertical direction in FIG. 4).
The opening 71 in the illustrated example is a rectangle (rectangle) in which the axis C1 passes through the position of the center of gravity, and has a two-fold symmetry (180-degree symmetry) that overlaps itself when rotated about the axis C1 by 180 degrees.
The opening 71 may have a square shape of n-fold symmetry (n is an integer greater than 2), for example, a 4-fold symmetry shape (90-degree symmetry) that overlaps itself when rotated 90 degrees around the axis C1.

As shown in FIGS. 3 to 6, a housing recess 72 including the peripheral edge 71 a of the opening 71 is formed in the lower surface 17 a 3 of the bottom plate 17 a.
The housing recess 72 is formed so as to be concave in the height direction of the transmission unit housing 12 (upward in FIG. 1), and can accommodate at least a part of the projection 82 of the power feeding unit housing 22 described later. .
The accommodation recess 72 in the illustrated example is a recess formed on the inner surface side of a projecting portion 72c having a top plate portion 72a and a peripheral plate portion 72b depending from the peripheral edge portion 72a1.
The top plate portion 72a is similar to the opening portion 71 and has a rectangular (rectangular) shape that is larger in length and width than the opening portion 71, and is formed in parallel with the bottom plate 17a. The peripheral edge 72 a 1 of the top plate 72 a is located away from the peripheral edge 71 a of the opening 71. For this reason, the top plate portion 72a has a rectangular frame shape having a predetermined width.

Similarly to the opening 71, the housing recess 72 can have a planar view shape that is rotationally symmetric in the direction around the axis C <b> 1.
The housing recess 72 in the illustrated example is a rectangle (rectangle) in which the axis C1 passes through the position of the center of gravity, and has a two-fold symmetry (180 degree symmetry) that overlaps itself when rotated 180 degrees around the axis C1.
The accommodating recess 72 may be a square having an n-fold symmetry (n is an integer greater than 2), for example, a 4-fold symmetry (90-degree symmetry).

At the four corners 72a2 of the rectangular frame-shaped top plate portion 72a, connector insertion openings 73 are formed, respectively.
These four connector insertion holes 73 (73a to 73d) are preferably formed so as to take relative positions that are rotationally symmetric in the direction around the axis C1. The coupling tool insertion port 73 in the illustrated example is formed at a two-fold symmetry (180 degree symmetry) position that overlaps when the transmission unit housing 12 is rotated 180 degrees around the axis C1. That is, when rotated 180 degrees around the axis C1, the positions of the connector insertion port 73a and the connector insertion port 73c are opposite to each other, and the positions of the connector insertion port 73b and the connector insertion port 73d are opposite to each other. Become.
For this reason, when the attitude | position of the transmission part housing | casing 12 around the axis | shaft C1 with respect to the electric power feeding part housing | casing 22 is changed 180 degree | times, the transmission part housing | casing 12 has the connector insertion port 73 in the same position as before change. become.

The four connector insertion holes 73 have n-fold symmetry (n is an integer greater than 2), for example, a positional relationship that is four-fold symmetry (90-degree symmetry) (the distance between adjacent connector insertion holes 73 is the same square) The arrangement may be as follows.
There is no limitation in particular in the number of the connector insertion ports 73, and it is good also as 1 or more arbitrary numbers. For example, it may be 2, 6, 8, etc. Even in this case, it is preferable that the connector insertion port 73 takes a relative position that is rotationally symmetric in the direction around the axis C1.
This relative position may be a position that is two-fold symmetric, or may be a position that is n-fold symmetric (n is an integer greater than 2), for example, four-fold symmetric (90-degree symmetric).

Engagement convex portions 74 and 74 are preferably formed at the center positions of the lower surfaces of the two side portions 72a4 and 72a4 (short sides) of the rectangular frame-shaped top plate portion 72a facing each other.

The shape of the engagement convex portion 74 is not particularly limited, but may be a cylindrical shape, a rectangular tube shape, a hemispherical shape, or the like.
The engagement convex portion 74 in the illustrated example is a head portion of the convex member 74a that is inserted into the engagement holes formed in the side portions 72a4 and 72a4 from the lower surface side and the nut is fastened from the upper surface side (see FIG. 3 and FIG. 3). (See FIG. 4).
As shown in FIG. 6, the protruding height of the engaging convex portion 74 from the top plate portion 72 a is preferably set to be smaller than the height dimension of the housing recess 72. As a result, the tip of the engaging projection 74 is positioned higher than the bottom plate 17a, and the engaging projection 74 does not come into contact with the ground or the like even when the transmission portion 1 is placed on a flat ground or the like. Workability can be improved.

The engaging protrusions 74 and 74 are preferably formed so as to take relative positions that are rotationally symmetric in the direction around the axis C1.
The engaging protrusions 74 and 74 in the illustrated example are formed at two-fold symmetry (180 degree symmetry) positions that overlap when the transmission unit housing 12 is rotated 180 degrees around the axis C1. That is, when rotating 180 degrees around the axis C1, the positions of the two engaging convex portions 74 and 74 are opposite to each other. For this reason, when the attitude around the axis C1 of the transmission unit casing 12 with respect to the power supply unit casing 22 is changed by 180 degrees, the transmission unit casing 12 has the engaging convex portion 74 at the same position as before the change. become.
There is no limitation in particular in the number of the engaging convex parts 74, It is good also as 1 or more arbitrary numbers. For example, it may be 4, 6, 8, etc. Even in this case, it is preferable that the engagement convex portion 74 takes a relative position that is rotationally symmetric in the direction around the axis C1.
This relative position may be a position that is two-fold symmetric, or may be a position that is n-fold symmetric (n is an integer greater than 2), for example, four-fold symmetric (90-degree symmetric).

The optical termination box 5 is installed on the outer surface of the transmission unit housing 12. As a result, the optical fiber cable wiring 62 (see FIG. 2) can be connected to the transmission unit 1 without being buffered with other wiring (metal cable wiring 61 and the like), and wiring work and the like are facilitated.
On the other hand, in the conventional information transmission apparatus 40 (see FIG. 11), the optical termination box is installed in the housing body 44, and the optical fiber cable wiring and other wiring are mixed, May interfere with wiring work.

It is possible to improve the maintainability by installing separately. For example, the AC power input unit 24 and the lightning arresters 23, 26A, and 26B can be arranged on the front side, and the uninterruptible power supply 25 can be arranged on the back side. In the case of this arrangement, the work frequency on the front side increases.
