The plurality of drain holes 56a are provided, for example, in the vicinity of the left front corner portion and the right rear corner portion of the lower wall portion 56, respectively.

  The plurality of drainage caps 7 are members that close the plurality of drainage holes 56a. The drain cap 7 is detachably attached to the drain hole 56a. The drainage cap 7 is attached to the drainage hole 56a as needed. Each drain cap 7 is attached to the drain hole 56a from the outside of the main body 5, for example. The drainage cap 7 is formed of a member having rubber elasticity (e.g., elastomer).

  As shown in FIG. 3, the drainage cap 7 has a substrate portion 7a, a tubular portion 7b, and a drainage groove 7c. The substrate portion 7a has a circular plate shape that is slightly larger than the drain hole 56a. The tubular portion 7b is a portion that is inserted into the drainage hole 56a, and has, for example, a cylindrical shape and has an outer diameter that is the same as the diameter of the drainage hole 56a. The tubular portion 7b is provided so as to rise upward from the center of the upper surface of the substrate portion 7a. The drainage groove 7c is a groove for draining moisture inside the main body 5 from the inside of the main body 5 to the outside. The drainage groove 7c has a vertical groove portion 7d and a horizontal groove portion 7e. The vertical groove portion 7d is provided on the outer peripheral surface of the tubular portion 7b along the tubular axis of the tubular portion 7b from the upper end portion to the lower end portion of the tubular portion 7b. The lateral groove portion 7e is provided on the upper surface of the substrate portion 7a along the radial direction of the substrate portion 7a from the lower end portion of the vertical groove portion 7d to the outer peripheral end of the substrate portion 7a.

  The drainage cap 7 is attached to the drainage hole 56a from the lower side of the lower wall portion 56. In this mounted state, the drain cap 7 blocks the drain hole 56a. However, the upper end portion 7f of the drain groove 7c of the drain cap 7 is connected to the internal space of the main body 5, and the lower end portion 7g of the drain groove 7c is connected to the outer space of the main body 5. Therefore, even when the drain cap 7 is attached to the drain hole 56a, the water inside the body 5 can be drained to the outside of the body 5 through the drain groove 7c.

  The plurality of closing caps 8 are members that close the plurality of electric wire insertion holes 56b. The closing cap 8 is detachably attached to the wire insertion hole 56b. The closing cap 8 is attached to the wire insertion hole 56b from the outside of the main body 5, for example. The closing cap 8 is attached to the wire insertion hole 56b as needed. The closing cap 8 is formed of a member having rubber elasticity (e.g., elastomer).

  Inside the main body 5, as shown in FIG. 2, a plurality of electric components 3 are housed. The plurality of electric components 3 are, for example, a transformer 31, a terminal block 32, a breaker 33, an electric wire fixing member 34, and a mounting base 35. The transformer 31 transforms (steps up or down) the input voltage and outputs it. The terminal block 32 is a component to which the electric wire inserted into the main body 5 from the electric wire insertion hole 56b is electrically connected. The breaker 33 is a component that switches the electric circuit in the breaker 33 to an open state or a closed state. The electric wire fixing member 34 is a member that fixes the electric wire inserted into the main body 5 through the electric wire insertion hole 56b. The mounting base 35 is a member that fixes the terminal base 32 and the breaker 33 to the main body 5. The transformer 31, the terminal block 32, and the breaker 33 are electrically connected so as to have a predetermined connection relationship. For example, the transformer 31, the terminal block 32, and the breaker 33 may be connected in the order of the input terminal block 32, the breaker 33, the transformer 31, and the output terminal block 32, or the input terminal block. 32, the transformer 31, the breaker 33, and the terminal block 32 for output may be connected in this order.

  The transformer 31 is arranged, for example, near the lower wall portion 56 of the left half portion of the internal space of the main body 5. That is, a heavy component such as the transformer 31 is arranged near the lower wall portion 56 from the viewpoint of stability. At that time, in order not to interfere with the wire insertion hole 56b, it is arranged in the left half portion of the internal space of the main body 5 on the side opposite to the arrangement of the wire insertion hole 56b. A gap is secured between the transformer 31 and the lower wall portion 56, and a gap is secured between the transformer 31 and the rear wall portion 52. The transformer 31 is fixed to the lower wall portion 56 and the rear wall portion 52.

  The terminal block 32 and the breaker 33 are attached to the attachment table 35. The mount 35 has a front panel 35a and a plurality of legs 35b. The plurality of legs 35b fix the front panel 35a to the front surface of the rear wall portion 52 (more specifically, the upper right half portion of the front surface). A space is secured between the front panel 35a and the rear wall portion 52. The front panel 35a has an upper region 35c and a lower region 35d. The upper region 35c is parallel to the rear wall portion 52, and the lower region 35d is inclined with respect to the rear wall portion 52 so as to face obliquely forward and downward.

  The terminal block 32 is attached to the front surface of the lower region 35d of the front panel 35a. For example, two terminal blocks 32 are provided, and the two terminal blocks 32 are arranged side by side. The terminal block 32 is, for example, a quick-connect terminal block and has, for example, three wire connection holes 32a. When the tip of the electric wire is inserted into the electric wire connection hole 32a, the electric wire and the terminal block 32 are electrically connected. The terminal block 32 is arranged above the electric wire insertion hole 56b of the lower wall portion 56. Since the lower region 35d is directed obliquely downward to the front, the central axis of the wire connection hole 32a of the terminal block 32 is directed obliquely downward to the front. Thereby, the electric wire can be easily inserted into the electric wire connection hole 32a from the lower side of the terminal block 32.

  The breaker 33 is attached to the upper area 35c of the front panel 35a (that is, an empty space above the terminal block 32). More specifically, the breaker 33 is arranged on the rear surface side of the front panel 35a and is exposed to the front from the opening 35e of the upper region 35c.

  The electric wire fixing member 34 is arranged on the upper surface of the lower wall portion 56, behind the electric wire insertion hole 56b. The wire fixing member 34 has a fixing member main body 34a and two leg portions 34b. The fixing member main body 34a has, for example, an elongated shape extending in the left-right direction (the direction in which the wire insertion holes 56b are arranged). The two leg portions 34b extend downward from the left and right ends of the fixing member main body 34a and are fixed to the upper surface of the lower wall portion 56. The fixing member main body 34a is provided with a plurality of through holes 34c. The plurality of through holes 34c penetrate in the front-rear direction and are arranged at intervals along the longitudinal direction of the fixing member main body 34a.

  In the wire fixing member 34, the binding band is passed through, for example, two adjacent through holes 34c among the plurality of through holes 34c. The binding band fixes the electric wire from the electric wire insertion hole 56b of the lower wall portion 56 to the fixing member main body 34a. The tip of the electric wire fixed to the electric wire fixing member 34 is electrically connected to the terminal block 32. By fixing the above electric wire to the electric wire fixing member 34, it is possible to suppress the above electric wire from coming off the terminal block 33 due to the load of the above electric wire.

  As shown in FIG. 1, the lid 6 has a front panel 61, an upper side wall 62 and a lower side wall 63. The front panel 61 is a portion that covers the opening 51 a of the main body 5. The upper side wall 62 is a portion protruding rearward from the upper end of the front panel 61. The lower side wall 63 is a portion protruding rearward from the lower end of the front panel 61. The left end 61a and the right end 61b of the front panel 61 are curved rearward in an arc shape, for example. The upper and lower ends of the left end 61a of the front panel 61 are connected to the left end of the upper side wall 62 and the left end of the lower side wall 63, respectively, and the upper and lower ends of the right end of the front panel 61 are connected to the right end of the upper side wall 62 and the right end of the lower side wall 63, respectively. ing.

  The lid 6 has four through holes 6a. The four through holes 6a are provided near the four corners of the front panel 61. That is, the four through holes 6 a are provided at positions corresponding to the four screw holes 58 a of the outer collar 58 of the lid body 6. The screw N1 passes through the through hole 6a from the front side of the front panel 61 and is screwed into the screw hole 58a corresponding to the through hole 6a. As a result, the lid body 6 is fixed to the front surface of the front wall portion 51 of the main body 5. That is, the opening 51 a of the front wall portion 51 is closed by the lid 6. The lid 6 can be removed from the main body 5 by removing the screw N1 from the screw hole 58a. That is, the lid 6 is detachably attached to the main body 5.

  As shown in FIGS. 1 and 4, the support member 9 projects downward from the lower surface 4a of the housing 4. The support member 9 has a pair of separation support portions 91, a front cover 92, and a rear cover 93.

  Each of the pair of separation support portions 91, the front cover 92, and the rear cover 93 is formed of, for example, a material having higher corrosion resistance than the housing 4 (for example, stainless steel). The pair of separation support portions 91, the front cover 92, and the rear cover 93 may be formed of the same metal as that of the housing 4, and the surfaces thereof may be plated with a member having higher corrosion resistance than the housing 4.

  The pair of separation support portions 91 are members that support the lower surface 4a of the housing 4 (that is, the lower surface of the lower wall portion 56). The pair of separation support portions 91 are arranged at intervals in the longitudinal direction (left-right direction) of the lower surface 4a. The pair of separation support portions 91 are arranged near both ends of the lower surface 4a in the longitudinal direction. The pair of separation support portions 91 are formed, for example, in a shape that is mirror image symmetric to each other. Hereinafter, of the pair of separation support parts 91, the left separation support part 91 is also referred to as a separation support part 91L, and the right separation support part 91 is also referred to as a separation support part 91R.

  As shown in FIG. 4, each of the pair of separation supporting portions 91 has a supporting portion main body 95, an extending portion 96, and a fixing portion 97.

  The support body 95 has a rectangular plate shape, for example. The outer main surface 95a (outer surface, first outer surface) of the supporting portion main body 95 faces the outer side in the facing direction (left-right direction) of the pair of separation supporting portions 91. The outer main surface 95a of the support portion main body 95 is the outer main surface of the main surfaces on both sides of the support portion main body 95. The facing direction of the pair of separation support portions 91 is a direction in which the pair of separation support portions 91 face each other. That is, the outer main surface 95a of the left separation support portion 91L faces the left direction, and the outer main surface 95a of the right separation support portion 91R faces the right direction. The outer main surface 95a of each of the pair of separation support portions 91 is, for example, perpendicular to the lower surface 4a of the housing 4.

  The support portion main body 95 has a plurality (for example, two) of electric wire insertion portions 95b (first electric wire insertion portion). The electric wire insertion portion 95b is a portion into which an electric wire is inserted, and is also a portion to which one end of a pipe through which an electric wire inserted into the electric wire insertion portion 95b is inserted is connected. The plurality of electric wire insertion portions 95b are arranged in the lateral width direction on the outer main surface 95a of the support portion main body 95.

  The electric wire insertion portion 95b is, for example, a knockout hole. More specifically, the wire insertion portion 95b has a knockout portion 95c. The knockout portion 95c is a portion that is detached from the support portion main body 95 when a mechanical impact (knockout) is applied. The knockout portion 95c is formed integrally with the support portion main body 95. The contour 95d of the knockout portion 95c is provided with, for example, a groove or a notch over the entire contour 95d. When a strong impact is applied to the knockout portion 95c, the knockout portion 95c is cut along the contour 95d, and a through hole is formed inside the contour 95d. This through hole penetrates in the thickness direction of the support portion main body 95. This through hole functions as a hole into which an electric wire is inserted or a hole to which a pipe is connected. The wire insertion portion 95b, which is a knockout hole, is used as a through hole by cutting off the knockout portion 95c as necessary. Since the electric wire insertion portion 95b is a knockout hole, it is used by making a hole by knockout if necessary. Therefore, the cost can be reduced. Further, since the wire insertion portion 95b is a knockout hole, the hole can be easily formed.

  The extension portion 96 is a portion that contacts the lower surface 4a of the housing 4. The extended portion 96 extends from the upper side portion (upper end portion) of the support portion main body 95 in the normal direction of the outer main surface 95a of the support portion main body 95 (outside in the opposing direction of the pair of separation support portions 9). That is, the extension portion 96 of the left separation support portion 91L extends in the left direction, and the extension portion 96 of the right separation support portion 91R extends in the right direction. The extending portion 96 is, for example, orthogonal to the outer main surface 95a of the support portion main body 95. The extension portion 96 is provided over the entire upper side portion of the support portion main body 95.

  The extended portion 96 has a plurality of (for example, two) through holes 96a. The through hole 96a is a hole into which a screw N2 for fixing the extension portion 96 to the lower surface 4a of the housing 4 is inserted. The plurality of through holes 96a are provided, for example, near both ends in the longitudinal direction (front-rear direction) of the extended portion 96. The extending portion 96 is fixed to the lower surface 4 a of the housing 4 by screwing the screw N2 inserted into the through hole 96 a into the screw hole of the lower surface 4 a of the housing 4. That is, the pair of separation support portions 91 are fixed to the lower surface 4 a of the housing 4.

  The extended portion 96 is fixed to the lower surface 4a of the housing 4 with a screw so that the upper surface of the extended portion 96 contacts the lower surface 4a of the housing 4. In this way, since the contact portion between the support member 9 and the lower surface 4a of the housing 4 is secured by the extending portion 96, the support member 9 can stably support the housing 4. At that time, the extension portion 96 extends from the upper side portion of the support portion main body 95 in the direction in which the outer main surface 95a of the support portion main body 95 faces. Therefore, the space between the extended portions 96 of the pair of separation support portions 91 can be secured as large as possible, and thus the pair of separation support portions 91 can more stably support the housing 4.

  The fixing portion 97 is a portion fixed to the arrangement surface on which the electric equipment 1 is arranged. The fixing portion 97 extends from the lower side portion (lower end portion) of the support portion main body 95 in the normal direction of the outer main surface 95a of the support portion main body 95 (outside in the opposing direction of the pair of separation support portions 91). That is, the fixed portion 97 of the left separation support portion 91L extends leftward, and the fixed portion 97 of the right separation support portion 91R extends rightward. The fixed portion 97 is, for example, orthogonal to the outer main surface 95a of the support portion main body 95. The fixing portion 97 is provided over the entire lower side portion of the support portion main body 95.

  The fixing portion 97 has a plurality (for example, two) of through holes 97a. The through hole 97a is a hole into which a screw for fixing the fixing portion 97 to the arrangement surface is inserted. The plurality of through holes 97a are provided near both ends of the fixed portion 97 in the longitudinal direction (front-back direction). The through hole 97a is, for example, a long hole extending in the longitudinal direction of the fixed portion 97. One end of the opening surface of the through hole 97a in the longitudinal direction (front-back direction) is open at the end of the fixing portion 97 in the longitudinal direction (front-back direction). The fixing portion 97 is fixed to the arrangement surface by screwing the screw inserted into the through hole 97a into the screw hole of the arrangement surface. That is, the pair of separation support portions 91 are fixed to the above arrangement surface.

  The fixing portion 97 is fixed to the above-mentioned arrangement surface with a screw so that the lower surface of the fixing portion 97 contacts the above-mentioned arrangement surface. In this way, since the support member 9 is fixed to the above arrangement surface by the fixing portion 97, the support member 9 can be stably arranged on the above arrangement surface. At this time, since the fixing portion 97 extends from the lower side portion of the supporting portion main body 95 in the direction in which the outer main surface 95a of the supporting portion main body 95 faces, the space between the fixing portions 97 of each of the pair of separation supporting portions 91. Can be secured as much as possible, whereby the support member 9 can be more stably arranged on the above arrangement surface.

The outer main surface 95a (outer surface) of 95 is disposed closer to the center of the lower surface 4a than the left side 4L (end portion) of the lower surface 4a. Thereby, the space S1 between the outer main surface 95a of the left separation support portion 91L and the left side 4L is connected to the electric wire or the electric wire insertion portion 95b inserted into the electric wire insertion portion 95b of the left separation support portion 91L. It can be used as a space for piping. The left side 4L of the lower surface 4a is an end portion of the lower surface 4a adjacent to the outer main surface 95a of the left separation support portion 91L in the normal direction (left direction) of the outer main surface 95a of the left separation support portion 91L. Is.

  Similarly, when viewed from a direction orthogonal to the lower surface 4a of the housing 4, the outer main surface 95a (outer surface) of the right separation support portion 91R is closer to the center of the lower surface 4a than the right side 4R (end portion) of the lower surface 4a. It is located in. Thereby, the space S2 between the outer main surface 95a of the right separation support portion 91R and the right side 4R is connected to the electric wire or the electric wire insertion portion 95b inserted into the electric wire insertion portion 95b of the right separation support portion 91. It can be used as a space for piping. The right side 4R of the lower surface 4a is an end portion of the lower surface 4a adjacent to the outer main surface 95a of the right separation support portion 91 in the normal direction (right direction) of the outer main surface 95a of the right separation support portion 91R.

  As shown in FIG. 4, the support member 9 has two outer surfaces 99L and 99R (first outer surfaces), an opening front surface 99F (second outer surface) 99F, and an opening rear surface 99K (second outer surface). Have.

  The two outer surfaces 99L and 99R are formed by the outer main surfaces 95a of the pair of separation support portions 91, respectively. That is, the left outer surface 99L is configured by the outer main surface 95a of the left separation support portion 91L, and the right outer surface 99R is configured by the outer main surface 95a of the right separation support portion 91R. The opening front surface 99F is an opening between the front edges of the support portion main bodies 95 of the pair of separation support portions 91. The opening rear surface 99K is an opening between the rear edges of the support portion main bodies 95 of the pair of separation support portions 91. The opening front surface 99F and the opening rear surface 99K are outer surfaces different from the two outer surfaces 99L and 99R.

  As shown in FIG. 4, the front cover 92 is a member that closes the opening front surface 99F of the support member 9, and is detachably attached to the opening front surface 99F. The front cover 92 has a cover body 92H, a left wall portion 92L, a right wall portion 92R, an upper wall portion 92U and a lower wall portion 92D.
