[0032] The battery cover 33 has a protruding portion 33c that protrudes outward from the side wall portions 22, 22 at a predetermined position in the vehicle width direction. For example, the protruding portion 33c projects outward from the pair of side wall portions 22, 22 in the vehicle front-rear direction of the battery carrier 20. The protruding portion 33c is disposed below the bent portion of the pressing member 27.

[0033] The battery cover 33 has a protruding cover portion 33d, a part of which protrudes in the vehicle width direction from the outer edge in the vehicle width direction. The protruding cover portion 33d is formed, for example, by a part of the peripheral wall portion 33b protruding outward in the vehicle width direction, and forms an accommodation portion 33e on the lower side, which is a space in which the end of the retainer 32 and the nuts 42 and washers 43, which are part of the fastening unit 40, are arranged. The protruding cover portion 33d covers the upper side and the outer periphery side of the engaging portion 32a of the retainer 32, the nuts 42, and the washers 43 arranged in the accommodation portion 33e. The protruding cover portion 33d also has a slit 33f through which the J bolt 41 penetrates in the vertical direction. For example, the slit 33f is formed to penetrate the protruding cover portion 33d in the vertical direction and reach the outer end in the vehicle width direction. In other words, the protruding cover portion 33d is a target portion through which the J bolt 41 passes and is clamped by the protector 50.

[0034] The fastening unit 40 includes a J bolt 41 which is a shaft member, a nut 42, and a washer 43. For example, the fastening units 40 are provided on both ends in the vehicle width direction of the upper end portion of the battery set 30A.

[0035] The J bolt 41 is a shaft member extending in the vertical direction, has a hook portion 41a with a return structure at one end, and has a tip portion 41b with a threaded portion at the other end.

The J bolt 41 extends upward from the hook portion 41a engaged with the bottom of the battery carrier 20, and passes through openings formed in the base plate 51, the protruding cover portion 33d, the retainer 32, the nut 42, the washer 43, and the support plate 52, and the tip portion 41b protrudes upward beyond the top wall portion 33a of the battery cover 33.

[0036] The nut 42 is screwed onto a threaded portion formed on the tip portion 41b side of the J bolt 41 via a washer 43. For example, the nut 42 is disposed on the engagement portion 32a of the retainer 32. The nut 42 regulates the position of the retainer 32.

[0037] In this embodiment, the fastening units 40 are provided at both ends of the battery set 30A in the vehicle width direction. Of these, the convex cover portion 33d and the protector 50 are provided above one fastening unit 40 on the outer side in the vehicle width direction and one engaging portion 32a of the retainer 32. That is, the engaging portion 32a of the retainer 32 arranged on the outer side of the vehicle 1 and the fastening unit 40 that fastens the engaging portion 32a are arranged in an accommodation portion 33e formed below the convex cover portion 33d of the battery cover 33.

[0038] The protector 50 is provided on the fastening unit 40 on the outside of the vehicle 1. The protector 50 includes a base plate 51 (base member), a support plate 52 (support portion), and a cover plate 53 (cover portion). For example, in this embodiment, the support plate 52 and the cover plate 53 are joined by welding to form a cover member 54.

[0039] The base plate 51 is a flat member made of sheet metal, and has a rod hole 51a that penetrates in the vertical direction as an opening through which the J bolt 41 passes. The base plate 51 is disposed facing the lower side of the convex cover portion 33d, for example, in a position along a plane perpendicular to the vertical direction. That is, the base plate 51 is disposed facing the convex cover portion 33d, sandwiching the engaging portion 32a of the retainer 32, the nut 42, and the washer 43, which are disposed in the housing portion 33e. That is, in this embodiment, the base plate 51 and the support plate 52 of the protector 50 sandwich the convex cover portion 33d and the engaging portion 32a of the retainer 32.

[0040] The support plate 52 is made of, for example, sheet metal. The support plate 52 is bent into a shape in which the central portion in the vehicle front-rear direction is convex upward in accordance with the outer surface of the convex cover portion 33d. The support plate 52 is disposed between the cover plate 53 and the convex cover portion 33d. The support plate 52 is disposed, for example, above the convex cover portion 33d.

[0041] For example, the support plate 52 has a top plate portion 52a, a pair of side plate portions 52b extending downward from the top plate portion 52a, and a pair of fixing plate portions 52c extending in a second direction from the lower edges of the pair of side plate portions 52b, which are integrally connected to each other.

[0042] The top plate portion 52a is a flat member and is disposed on the upper surface of the convex cover portion 33d. The top plate portion 52a has a slit 52d as an opening through which the J bolt 41 passes. For example, the slit 52d opens at an end portion in one direction. As an example, the slit 52d opens toward the inside in the vehicle width direction, which is the opposite side to the slit 33f of the convex cover portion 33d. The top plate portion 52a is disposed opposite to the base plate 51, sandwiching the convex cover portion 33d and the fastening portion of the fastening unit 40 between the top plate portion 52a and the base plate 51.

[0043] The pair of side plate portions 52b are plate-shaped portions extending downward from both edges of the top plate portion 52a in the front-rear direction of the vehicle body.

[0044] The fixing plate portion 52c is a plate-like portion extending in the front-rear direction of the vehicle body from the lower end edge of the side plate portion 52b. The fixing plate portion 52c has a fastening hole 52e in which a fastening member such as a bolt 73a for fastening to the base plate 51 is disposed. The fixing plate portion 52c is disposed on the base plate 51 and is fastened to the base plate 51 by a fastening portion 73 having, for example, a bolt 73a, a nut 73b, and a washer 73c. ​​For example, the nut 73b of the fastening portion 73 is a wing nut.

[0045] The cover plate 53 includes a pair of side plate portions 53a and a roof portion 53b that covers the upper side of the tip portion 41b.

[0046] The pair of side plate portions 53a are plate-shaped portions extending upward from the end edges of the pair of fixing plate portions 52c in the vehicle body front-rear direction.

[0047] The roof portion 53b has a pair of inclined plates 53c that are close to each other and extend upward from the upper edges of the pair of side plate portions 53a and are continuous at a central apex. The roof portion 53b has a corner at the apex where the pair of inclined plates 53c are continuous, and is configured in an angular shape that widens downward from the apex when viewed in the vehicle width direction.

[0048] The roof portion 53b has a base portion 53d arranged above the convex cover portion 33d and the fastening portion of the engaging portion 32a of the retainer 32, and an extending portion 53e extending from the base portion 53d toward the inside in the vehicle width direction above the battery cover 33. For example, the base portion 53d covers the upper side of the tip portion 41b of the J bolt 41 above the convex cover portion 33d. The extending portion 53e is disposed opposite to the top wall portion 33a of the battery cover 33 with a predetermined gap therebetween. That is, the roof portion 53b has a cantilever structure in which it is supported on the outer side in the vehicle width direction and the inner side in the vehicle width direction is a free end.

[0049] For example, the roof portion 53b has an outer end in the vehicle width direction positioned outside the position where the J bolt 41 is arranged, and an inner end in the vehicle width direction positioned inside the cabin 60 arranged on the battery unit 12, for example, positioned outside the center of the battery cover 33 in the vehicle width direction.

[0050] The steps for assembling the battery unit 12 configured as above will be described with reference to FIGS.

[0051] First, as shown in FIG. 6, a plurality of batteries 30 are placed on the bottom wall portion 23 of the battery carrier 20, and the retainer 32 is fixed by the J bolt 41. Specifically, the retainer 32 is placed over the plurality of batteries 30, and the shaft portion of the J bolt 41 is inserted into the opening 32b formed in the engagement portion 32a at both ends of the retainer 32. At this time, the hook portion 41a of the J bolt 41 is engaged with the bracket base 26, and a washer 43 and a nut 42 are attached near the tip portion 41b and above the engagement portion 32a of the retainer 32. Note that the base plate 51 is previously interposed on the J bolt 41. That is, the J bolt 41 is assembled to the retainer 32 with the J bolt 41 inserted into the opening of the base plate 51. For example, the base plate 51 is placed near the hook portion 41a of the J bolt 41 until it is later fixed to the fixing plate portion 52c.

[0052] 5 to 7, the battery cover 33 is placed over the upper side of the battery 30 and attached. At this time, the engaging portion 32a of the retainer 32, the washer 43, and the nut 42 are housed in the housing portion 33e on the back side of the convex cover portion 33d of the battery cover 33, and the tip portion 41b of the J bolt 41 protrudes upward beyond the convex cover portion 33d.

[0053] Next, the protector 50 is attached. Specifically, the base plate 51 is lifted and placed opposite the lower side of the convex cover portion 33d, and the fixing plate portion 52c is attached to the upper side. The fixing plate portion 52c and the base plate 51 are then fastened to each other by the fastening portion 73.

[0054] According to the protector 50 and the vehicle 1 of the present embodiment, the tip 41b of the shaft member such as the J bolt 41 protruding and exposed from the target portion can be covered by the roof portion 53b of the protector 50. Therefore, for example, when the tip 41b of the J bolt 41 is arranged facing upward at the bottom of the cabin 60, it is possible to prevent the tip 41b from being caught on the clothes or other surrounding members when the occupant gets in and out of the vehicle. In addition, the roof portion 53b is formed into a triangular shape having a corner at the apex by the pair of inclined plates 53c, and therefore, since the area of ​​the apex is small, for example, when the battery unit 12 is arranged near the cabin 60, it is possible to prevent the occupant from placing his / her feet on the triangular shape. Therefore, it is possible to prevent the fastening unit 40 and the like from being damaged by the load caused by the occupant getting in the vehicle. In addition, the protector 50 according to the above embodiment can fix the protector 50 and also fix the battery cover 33 by clamping a part of the battery cover 33, which is the target portion, between the base plate 51 and the support plate 52.

[0055] Although one embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment and can be modified, improved, etc. as appropriate. The present invention is defined by the claims and includes all modifications within the meaning and scope of the claims.

[0056] For example, the shape and material of the plate-like members constituting the protector 50 are not limited to those in the above embodiment. For example, although an example has been shown in which the plates 51, 52, and 53 are made of sheet metal, the present invention is not limited to this, and each member may be made of resin, for example.

[0057] In the first embodiment, the roof portion 53b is exemplified as a triangular roof portion 53b having a pair of inclined plates 53c, 53c, but the present invention is not limited to this. Fig. 8 is an explanatory diagram showing a battery unit 12A according to another embodiment, and Fig. 9 is an explanatory diagram showing a battery unit 12B according to another embodiment. Note that the battery units 12A and 12B shown in Figs. 8 and 9 are partially different in the shapes of the base plate 51, the support plate 52, and the cover plate 53, but are otherwise similar in configuration to the battery unit 12.

[0058] For example, as another embodiment, roof portion 53b may have flat apex 53f as shown in Fig. 8. Alternatively, roof portion 53b may have apex 53g that curves upward and has an arc-shaped cross section as shown in Fig. 9.

[0059] In the above embodiment, the cover member 54 is formed by welding the support plate 52 and the cover plate 53 to each other, but the present invention is not limited to this. For example, as shown in FIG. 8, the support plate 52 and the cover plate 53 may be formed separately and fastened by a fastening portion 73. The base plate 51 is exemplified as having a flat shape, but the present invention is not limited to this. For example, as shown in FIG. 8 and FIG. 9, a base plate 51A having a wall-like portion bent into an L-shaped cross section and facing the side surface of the battery 30 may be used as another embodiment. The protector 50 may be configured not to include the support plate 52. For example, the protector 50 may be configured to fasten the support plate 52 by screwing a wing nut onto the support plate 52.

[0060] In the above embodiment, the engaging portion 32a of the retainer 32 and the protruding cover portion 33d that is a part of the battery cover 33 are fastened as the target portion, but the present invention is not limited to this. For example, a configuration may be adopted in which the battery cover 33 is not provided, and only the engaging portion 32a of the retainer 32 is the target portion.

[0061] Also, an example has been shown in which the target portion includes the engaging portion 32a of the retainer 32 for fixing the battery 30 of the vehicle 1, but the present invention is not limited to this. For example, the target portion may be another member provided on the shaft member, or may be applied to something other than the vehicle 1. For example, by sandwiching various target portions inserted or screwed into a shaft member such as a bolt between the base plate 51 and the support plate 52, the shaft member can be covered and protected, and the protector 50 can be fixed.

[0062] Furthermore, although rod hole 51a formed in base plate 51 and slit 52d formed in support plate 52 have been exemplified as openings through which J bolt 41, which is an axial member, is inserted, the present invention is not limited to these and can be modified as appropriate. For example, a hole may be formed on the support plate 52 side and a slit may be formed in base plate 51, or holes may be formed in both support plate 52 and base plate 51. For example, slits opening in opposite directions may be formed in both base plate 51 and support plate 52.
