For this reason, it becomes possible to set it as the drainage member 5 which drains the water in the electric equipment storage box 1 outside easily.

  The electric device storage box 1 of the present embodiment includes a housing body 18 having an opening and a door 19 that closes the opening. The electrical equipment storage box 1 is provided with drain holes 12 at the corners of the bottom surface 11 for draining water accumulated in the housing body 18 due to condensation or the like. By fitting the drainage member 5 into the drainage hole 12, it is possible to drain the water inside the electric equipment storage box 1 and to prevent water from entering from the outside. In addition, since the drainage member 5 of this embodiment is a product made from rubber | gum, adhesiveness with the electric equipment storage box 1 is good, and can improve waterproof performance. The material of the water draining member 5 is not particularly limited, and may be made of plastic.

  The drainage member 5 of the present embodiment is configured to be able to introduce water that has entered the electrical equipment storage box 1 into the drainage member 5 through the drainage space 3. As understood from FIG. 3, the drainage space 3 in the present embodiment is formed so as to extend in the vertical direction. Therefore, water can move in the vertical direction along the drainage space 3. Further, the drain hole 52 is formed as a through hole extending in the vertical direction. Therefore, water can move in the vertical direction along the drain hole 52. Through this drain hole 52, the water inside the drainage member 5 is drained to the outside.

  The drainage space 3 and the drainage hole 52 are connected by a flow path 53. As shown in FIG. 6, the flow path 53 in the present embodiment is formed along the peripheral edge of the drainage member 5 across the drain space 3 and the drain hole 52. The water that has moved from the housing body 18 to the drainage space 3 then moves along the flow path 53 in the horizontal direction. With such a configuration, it is possible to form a longer path between the drain space 3 and the drain hole 52. In addition, the flow path 53 in the embodiment is formed in a substantially arc shape in plan view along the periphery of the water draining member 5.

  In the present embodiment, the protrusions 59 are connected by the reinforcing rib 7. In the present embodiment, the drainage reinforcement ribs 7 a and 7 b of the reinforcement rib 7 are also used to configure the drainage space 3. Since the drainage space 3 is formed by the drainage reinforcing ribs 7a and 7b that connect the projections 59, even if the projections 59 are enlarged to facilitate drainage, the locking pieces to the electrical equipment storage box 1 are provided. A holding force of 58 can be maintained. Further, the drainage reinforcement ribs 7 a and 7 b of the present embodiment are provided so as to extend to a position higher than the locking piece 58. For this reason, it becomes possible to enlarge the drainage space part 3, and it becomes possible to drain the water in a housing | casing rapidly.

  The reinforcing rib 7 of the present embodiment includes a circular rib 71 having a circular shape in plan view and a protruding rib 72 extending from the circular rib 71 toward the radially outer side. A plurality of protruding ribs 72 are provided and connected to the protruding portion 59. With such a configuration, the strength can be increased. The drainage reinforcement rib 7 a is a part of the protruding rib 72, and the drainage reinforcement rib 7 b forms a part of the circular rib 71.

  As shown in FIG. 1, the drainage member 5 is configured such that a base portion 57 that forms a bottom portion forms a substantially circular surface. As can be understood from FIGS. 3 and 4, the base 57 is formed in a size that can cover the drain hole 12. As shown in FIG. 7, the water draining member 5 is provided with a protrusion 59 extending upward from the base 57. The drainage member 5 is fixed to the bottom surface 11 of the electrical equipment storage box 1 by inserting the projection 59 into the drainage hole 12 while elastically deforming the latching portion 58 and locking the locking piece 58. In a state where the drainage member 5 is fitted to the electrical equipment storage box 1, the base 57 is arranged so as to cover the drainage hole 12 when viewed from below.

  In the present embodiment, the protrusion 59 of the water draining member 5 is formed in a substantially arc shape in plan view so as to be elastically deformable. The protrusion 59 includes a locking piece 58 that protrudes outward. When the drainage member 5 is attached, the locking piece 58 is a part that moves from the lower side to the upper side of the bottom surface 11, and the locking piece 58 is caught on the bottom surface 11, and the draining member 5 is prevented from dropping down. doing. As can be understood from FIG. 5, the locking piece 58 of the present embodiment is configured so as not to be formed at a portion where the drainage space 3 is formed.

  As can be understood from FIGS. 5 and 6, a wall portion 54 is provided between the drainage space portion 3 and the drainage hole 52 in the present embodiment. Further, as can be understood from FIG. 7, the wall portion 54 is configured to extend upward from the base portion 57 and is a constituent element of the flow path 53 through which water passes. The wall portion 54 is configured to be able to come into contact with the bottom surface 11 of the electric device storage box 1. When the wall portion 54 comes into contact with the bottom surface 11 of the electric device storage box 1, It is possible to prevent water from getting over the upper side of the wall portion 54.

  An outer wall portion 56 extending upward from the base portion 57 is formed on the outer peripheral portion of the base portion 57 and is configured to be able to contact the bottom surface 11 of the housing body 18. Since the outer wall part 56 is located outside the wall part 54, water can be prevented from entering the flow path 53 from other than the drain hole 52 penetrating in the vertical direction.

  As can be understood from FIGS. 5 to 7, the wall portion 54 is arranged so as to divide a part of the space between the outer wall portion 56 and the locking piece 58, and enters from the drain hole 52. It is possible to divert the water that has been removed. For this reason, it becomes possible to set it as the structure which cannot arrive at the drainage space part 3 easily.

  In the present embodiment, a gap portion 55 through which water can move is formed between the end portions of the wall portion 54. In this way, a part of the path from the drain hole 52 to the drain space 3 is bent in a substantially crank shape. The water that has entered the drainage member 5 from the drain hole 52 needs to pass through a path through the gap 55 before reaching the drain space 3. For this reason, it becomes possible to suppress intrusion of water into the housing body 18. As shown in FIG. 6, in this embodiment, four wall portions 54 formed in an arc shape in a plan view are positioned on the same circle so as to form an approximate circle, so that four gap portions are formed. 55 is formed.

  Further, in the present embodiment, a branch portion 64 extending in the direction of the outer wall portion 56 located outside the inner wall portion 66 from the inner wall portion 66 that is the projection portion 59 provided with the locking piece 58 is integrally provided with the base portion 57. . When the branch part 64 is provided to branch the water path, it is possible to suppress the water that has entered from the drain hole 52 from reaching the drain space part 3.

  By the way, when the drainage member 5 is fitted, the drainage member 5 may be deformed. However, in this embodiment, since the branch part 64, the inner wall part 66, and the base part 57 are integrally formed, even if the water draining member 5 is deformed, the force to return to the original becomes easy to work. Moreover, when the drainage member 5 is press-fitted into the drainage hole 12, the branching portion 64 abuts on the electric device storage box 1, so that excessive deformation can be suppressed. The branch part 64 can also be formed integrally with the outer wall part 56. Also in this case, the branch part 64 can suppress the deformation of the water draining member 5. However, since the inner wall portion 66 that is the projection portion 59 to which the reinforcing rib 7 is connected has higher strength, the branch portion 64 is preferably formed integrally with the inner wall portion 66 that is the projection portion 59.

  In the present embodiment, the branch portion 64 is provided between the end portions of the wall portion 54. For this reason, it is possible to make it difficult for water entering from the outside through the drain hole 52 to reach the drain space 3.

  In the present embodiment, two protrusions 59 are provided, and two drainage spaces 3 are provided. If it does in this way, since the site | part used for the drainage space part 3 can be suppressed, the site | part which can be utilized as the latching piece 58 can be ensured. For this reason, it can suppress that the latching strength by the latching piece 58 falls.

  In the present embodiment, two drain holes 52 are formed. More specifically, the drainage space portion 3 and the drainage hole 52 are formed so that the line connecting the two drainage space portions 3 and the line connecting the two drainage holes 52 are orthogonal to each other in plan view. Therefore, the path from the drainage hole 52 to the drainage space 3 is lengthened, and water can be prevented from entering the electrical equipment storage box 1 from the drainage hole 52. In FIG. 6, a line connecting the drain holes 52 and a line connecting the drain space portions 3 are indicated by broken lines.

  The drain hole 52 and the drain space 3 are both provided adjacent to the wall 54. Further, the gap portion 55 between the end portions of the wall portion 54 is provided so as to be positioned between the drainage space portion 3 and the drainage hole 52. More specifically, when considering an intersection where a line connecting the two drainage space portions 3 and a line connecting the two drainage holes 52 intersect in plan view, the intersection point and the line connecting the drainage space portion 3 and the intersection point The angle formed by the line connecting the gap portion 55 is approximately 45 degrees. Similarly, the angle formed by the line connecting the intersection and the drainage hole 52 and the line connecting the intersection and the gap 55 is approximately 45 degrees. Moreover, as shown in FIG. 6, it forms so that it may become symmetrical in planar view. By setting it as such a structure, all the shortest paths from each drain hole 52 to each drain space part 3 become the same length.

  Moreover, as can be understood from FIG. 7, in the embodiment, the drainage space portion is more than the surface provided with the drainage holes 52 that discharge the water that has passed through the drainage space portion 3 to the outside of the electrical equipment storage box 1. The step portion 68 is provided so that the lower end of 3 is positioned higher than the surface on which the drain holes 52 are provided. Therefore, the water that has entered from the drainage groove is prevented from reaching the drainage space 3.

  Drawing 8 is a figure which looked at draining member 5 in an embodiment from the lower side. As can be understood from FIG. 8, in the present embodiment, an arc-shaped drain hole 52 is formed in accordance with the arc-shaped channel 53 in plan view. The drain holes 52 are arranged so as to face each other with the center point of the base 57 interposed therebetween. In addition, on the lower surface of the base portion 57, other than the drainage hole 52, no portion where water can enter into the drainage member 5 is formed.

  As mentioned above, although one embodiment has been described, the present invention is not limited to the above-described embodiment, and various modes can be adopted. For example, the number of drainage spaces is not limited to two, and may be one or three or more.

  There is no need to provide four gap portions, and it is possible to form one gap portion by providing one substantially C-shaped wall portion in plan view. Moreover, it is also possible to form an appropriate number of gaps by using a plurality of walls other than four.

  It is also possible to adopt a configuration in which no wall portion is provided. It is also possible to adopt a configuration in which the height of the wall portion does not contact the bottom surface of the housing body. Similarly, it is possible to adopt a configuration in which the outer wall portion does not contact the bottom surface of the housing body.

  The drain hole may not be a hole penetrating in the vertical direction. For example, a hole penetrating the drain hole in the left-right direction can be used. Moreover, the external shape of a base part and a latching | locking part can be changed suitably.

  The reinforcing rib may not be configured to have a circular portion in plan view at the center. For example, it is good also as a structure provided with the polygonal site | part, and the structure which extends a protrusion rib toward the latching piece from the site | part.
