  As shown in FIG. 6B, the standing plate 21c arranged on the floor side is inclined downward with respect to the back plate 21a. That is, in a state where the storage member 20 is attached to the side structure 5, the standing plate 21c is inclined downward in the direction from the back plate 21a toward the inspection lid 10 (see FIGS. 3 and 4). Accordingly, the water that has entered the storage member 20 (container body 21) does not stay, and the water can flow down toward the drain hole 11c and can be discharged to the outside more quickly.

  Moreover, it becomes possible to position the drain hole 11c in the deepest part of the space where water is stored by the downward inclination of the standing plate 21c. Therefore, it is possible to improve the efficiency of discharging the water that has entered the storage member 20 (container body 21) to the outside. In the present embodiment, the drain hole 11c is located at a position where the inclination direction of the standing plate 21c is extended (see FIGS. 3 and 4).

  In the standing plate 21d, two piping holes 21d1 through which piping is inserted are opened. Using this pipe hole 21d1, the pipe is connected to the open valve DV housed in the housing member 20 (see FIGS. 3 to 5). In this case, since the piping hole 21d1 is disposed sufficiently above the drain hole 11c (see FIGS. 3 and 4), water that has entered the storage member 20 enters the inside of the vehicle body from the piping hole 21d1. Never do.

  The extending plate 21f is formed with insertion holes 21f1 at a plurality of locations (three locations in the present embodiment). Further, a screw receiver 23 is disposed on the back surface of the extended plate 21f (the surface on the right side in FIG. 6B) corresponding to the insertion hole 21f1. The screw receiver 23 is formed with a female screw hole 23a communicating with the insertion hole 21f1. A female screw is threaded on the inner peripheral surface of the female screw hole 23a, and a bolt B inserted into the insertion hole 21f1 of the extension plate 21f is fastened (screwed) (see FIGS. 3 and 4). ).

  The flange portion 22 is a plate-like member to which the bolt B is fastened and fixed (see FIGS. 3 to 5), and is disposed at an open end on one surface side (left side in FIG. 6B) of the container body 21. , Extending inwardly from its open end. In the present embodiment, as shown in FIG. 6A, the flange portion 22 is formed of a U-shaped plate-like body as viewed from the front, and the other standing plates 21b, 21d, excluding the standing plate 21c. It is arrange | positioned at the open end (standing end) of 21e.

  The front surface of the flange portion 22 (the left side surface in FIG. 6B) is the front surface of the extended plate 21f of the container body 21 as shown in FIGS. 6B and 7A (FIG. 6). (B) It is arrange | positioned in the position which becomes flush | planar with the left surface. Therefore, the flange part 22 and the extended board 21f can be made to adhere | attach on the back surface of the outer surface board 5a of the side structure 5 equally over the whole surface (refer FIG.3 and FIG.4).

  In the flange portion 22, female screw holes 22 a communicating with the insertion holes 5 e drilled in the outer surface plate 5 a of the side structure 5 when attached to the side structure 5 are formed at a plurality of positions (seven positions in the present embodiment). Is done. A female screw is threaded on the inner peripheral surface of the female screw hole 22a, and a bolt B inserted into the insertion hole 5e of the outer surface plate 5a is fastened (screwed) (see FIGS. 3 and 4). .

  Returning to FIG. 2 to FIG. A plurality of (four in the present embodiment) contact portions 30 are disposed on the outer surface side of the container body 21 of the storage member 20. Each of these contact portions 30 is formed in a rectangular plate shape when viewed from the front, and the outer surface of the container body 21 (standing plates 21b to 21e) and the back surface of the inner surface plate 5b of the side structure 5 (the right side surface in FIGS. 3 and 4). ) And each.

  Here, in the storage member 20, the flange portion 22 is fastened and fixed to the outer surface plate 5 a of the side structure 5, and the container body 20 protrudes from the flange portion 22. Therefore, the container body 20 is unstable with respect to vibration during traveling. On the other hand, the container body 20 can be stably held by connecting the outer surface of the container body 20 to the back surface of the inner surface plate 5b of the side structure 5 using the contact portion 30. As a result, for example, loosening of the bolt B can be suppressed.

  The contact portion 30 is formed from a rectangular plate-like body as viewed from the front, and a plurality of (four in the present embodiment) are the outer surface of the container body 21 (standing plates 21b to 21e) and the inner side of the side structure 5. The back surface of the face plate 5b is connected to each other. In this case, each abutting portion 30 is welded and fixed to the back surface of the inner surface plate 5b of the side structure 5 on one side of the plate-like body, and the container body 21 (standing plates 21b to 21e) on the other side of the plate-like body. ) Are fixed to the outer surface of each by welding.

  In this case, the shape of the contact portion 30 is a rectangular plate shape, and the plate body is placed on the back surface of the inner surface plate 5 b of the side structure 5, and one side thereof is abutted against the outer surface of the container body 21. It only needs to be fixed by welding. That is, the shape of the plate-like body can be simplified and the efficiency of the assembly process can be achieved, and the product cost can be reduced accordingly.

  Next, an assembling method for assembling the inspection lid 10 and the storage member 20 to the side structure 5 will be described. The storage member 20 is inserted and arranged from the inside of the vehicle body into the opening 5d of the side structure 5, and the flange portion 22 and the extension plate 21f are disposed on the back surface of the outer surface plate 5a of the side structure 5 (the right side surface in FIGS. 3 and 4). ). In this case, the hole positions of the female screw portion 22a of the flange portion 22 and the insertion hole 21f1 of the extending plate 21f are made to coincide with the hole positions of the insertion holes 5e in the outer surface plate 5a of the side structure 5.

  The inspection lid 10 is arranged at a position that covers the opening 5d of the side structure 5 from the outside of the vehicle body (outer wall surface side), and the fixing plate 11 is a surface of the outer surface plate 5a of the side structure 5 (the surface on the left side in FIGS. 3 and 4). ). In this case, the hole position of the insertion hole 11 d of the fixed plate 11 is made to coincide with the hole position of the insertion hole 5 e in the outer surface plate 5 a of the side structure 5. In addition, as for arrangement | positioning to the side structure 5 of the storage member 20 and the inspection lid | cover 10, any may be first.

  Next, the bolts B are inserted into the insertion holes 11d of the fixing plate 11 of the inspection lid 10, and the bolts B are passed through the insertion holes 5e of the outer surface plate 5a or the insertion holes 21f1 of the extension plate 21f, and the flanges. The internal thread portion 22a of the portion 22 or the internal thread portion 23a of the screw receiver 23 is screwed. Thereby, as shown in FIGS. 2 to 5, the inspection lid 10 and the storage member 20 are assembled to the side structure 5.

  In addition, after these assembly | attachment, the open valve DV is piped using the piping hole 21d1. Further, the contact plate 30 is welded and fixed as described above, and the container body 21 of the storage member 20 and the inner surface plate 5b of the side structure 5 are connected.

  As described above, the storage member 20 extends the flange portion 22 of the container body 21 inward, and attaches the flange portion 22 along the opening 5a of the side structure 5 from the inside of the vehicle body. Since the inspection lid 10 (fixing portion 11) is fastened and fixed to the bolt 22 by the bolt B, even if water enters from the insertion hole 11d, the insertion hole 5e, etc., the water enters the container body 21 of the storage member 20 (that is, inspection). It can be restrained (stored) in the interior space formed between the lid 10 and the storage member 20 and prevented from entering the vehicle body.

  In this case, the flange portion 22 and the extension plate 21f of the storage member 20 are brought into contact with the back surface side of the outer surface plate 5a of the side structure 5, and the inspection plate 10 is fixed to the front surface side of the outer surface plate 5a of the side structure 5. 11 are brought into contact with each other, and the overlapped portions of the fixing plate 11 of the inspection lid 10, the outer surface plate 5a of the side structure 5 and the flange portion 22 or the extension plate 21f of the storage member 20 are fastened and fixed by bolts B. Therefore, the inspection lid 10 and the storage member 20 can be firmly fixed to the side structure 5.

  Further, in this way, the fixing plate 11 of the inspection lid 10, the outer surface plate 5a of the side structure 5 and the flange portion 22 or the extension plate 21f of the storage member 20 are overlapped, and the overlapped portion is fastened and fixed by the bolt B. With the structure, the number of bolts B required for fastening and fixing can be reduced. That is, for example, the bolt B for fastening and fixing the flange portion 22 of the storage member 20 to the side structure 5 and the bolt B for fastening and fixing the inspection lid 10 to the side structure 5 can be used. As a result, it is possible to reduce the number of parts, thereby reducing weight and reducing product cost.

  In this case, since the inspection lid 10 has a structure in which the fixing portion 11 is formed in a frame shape when viewed from the front, and the central opening of the fixing portion 11 is opened and closed by the opening / closing lid portion 12, the seal portion 13 has a continuous shape as described above ( Endless shape). Therefore, it is easy to ensure the performance (waterproof performance) that makes the space between the fixed portion 11 and the opening / closing lid portion 12 watertight.

  Moreover, the inspection lid | cover 10 can be unitized by setting it as such a structure. Therefore, it is not necessary to ensure the waterproof performance due to the relationship between the other members that do not constitute the unit and the seal portion 13, and the waterproof performance can be ensured only by the relationship between the members that constitute the unit. That is, it is only necessary to be able to define the relationship between the seal portion 13 and the open / close lid portion 12. For example, it is not necessary to ensure the watertightness by bringing the seal portion 13 into contact with a member outside the unit. Therefore, the tolerance at the time of assembling to the side structure 5 can be relaxed (that is, even if the mounting position of the inspection lid 10 with respect to the side structure 5 is slightly shifted, the watertight performance is not affected). Cost can be reduced.

  Next, a second embodiment will be described with reference to FIGS. In the first embodiment, the case where the flange portion 22 is formed in a U-shape when viewed from the front is described. However, the flange portion 222 in the second embodiment is formed in a frame shape when viewed from the front. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment mentioned above, and the description is abbreviate | omitted.

  As shown in FIGS. 8 and 9, in the second embodiment, the flange portion 222 disposed at the open end on the one surface side of the container body 221 is continuously formed in the circumferential direction, and the outer surface plate of the side structure 5. The number of female screw holes 22a corresponding to the positions corresponding to all the insertion holes 5e in 5a (that is, all the insertion holes 11d in the fixing portion 11 of the inspection lid 10) is formed.

  In this way, when the flange portion 222 is formed in a frame shape when viewed from the front, and the inspection lid 210 is fastened and fixed to the flange portion 222, all the bolts B enter through the insertion holes 11d and the insertion holes 5e. It is possible to prevent the water to be retained in the container body 21 of the storage member 220 and enter the vehicle body.

  In the second embodiment, a hole 211c is formed in the fixing portion 11, a hole 205f is formed in the outer surface plate 5a of the side structure 5, and a hole 222b is formed in the flange portion 222. In a state where the lid 210 and the storage member 220 are assembled to the side structure 205, these holes 211c, 205f, and 222b are communicated with each other and function as drain holes.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed.

  The numerical values given in the above embodiments are merely examples, and other numerical values can naturally be adopted. For example, the number of bolts B and the number of insertion holes 11d associated therewith, or the number of drain holes 11c can be changed as appropriate.
