Therefore, both end portions of the fixed surface in the direction orthogonal to the direction in which the battery cells 11 are arranged are the first end portion 24a and the second end portion 24c in the longitudinal direction of the third covering portion 24. The first end 24a is the first end, and the longitudinal second end 24c is the second end. Further, when the surface 30, the surface 38, and the surface 39 are fixed surfaces, among the both end portions 26a, 27a in the direction orthogonal to the parallel arrangement direction of the battery cells 11 on the surface 30, the surface 38, and the surface 39, The end portion 26a is the first end portion, and the end portion 27a on the leg portion 27 side is the second end portion. With reference to the support portions 33 and 44, the first end 24a in the longitudinal direction of the third cover 24 and the end 26a are located in the same direction, and the second end 24c in the longitudinal direction of the third cover 24 The end 27a is located in the same direction.
第１の立設部３１と第２の立設部４２は、配線６１を支持している。第１の立設部３１において、第３の被覆部２４の長手方向第１端部２４ａ側の面３１ａは、配線６１と対向している。第２の立設部４２において、第３の被覆部２４の長手方向第２端部２４ｃ側の面４２ａは、配線６１と対向している。したがって、第１の支持部３３における第３の被覆部２４の長手方向第１端部２４ａ側の一部分が配線６１と対向し、第２の支持部４４における第３の被覆部２４の長手方向第２端部２４ｃ側の一部分が配線６１と対向している。 The first standing portion 31 and the second standing portion 42 support the wiring 61. In the first standing portion 31, the surface 31 a on the first end portion 24 a side in the longitudinal direction of the third covering portion 24 faces the wiring 61. In the second standing portion 42, the surface 42 a on the second end portion 24 c side in the longitudinal direction of the third covering portion 24 faces the wiring 61. Therefore, a part of the first support portion 33 on the first end portion 24a side in the longitudinal direction of the third covering portion 24 faces the wiring 61, and the third support portion 24 in the longitudinal direction of the third covering portion 24 in the second support portion 44 A part on the side of the two end portions 24 c faces the wiring 61.
また、図２に示すように、第１の延設部３２及び第２の延設部４３は、面３０と対向する面３２ａ，４３ａが、配線６１と対向している。第１の立設部３１と第２の立設部４２に支持される配線６１は、屈曲して設けられている。 As shown in FIG. 2, the first extending portion 32 and the second extending portion 43 have surfaces 32 a and 43 a facing the surface 30 facing the wiring 61. The wiring 61 supported by the first standing part 31 and the second standing part 42 is bent and provided.
次に、本実施形態の電池モジュール１０の作用について説明する。
電池モジュール１０に振動などが加わり、配線６１が移動しようとすると、第３の被覆部２４、第１の立設部３１、第２の立設部４２、第１の延設部３２及び第２の延設部４３によって配線６１の移動が抑制される。このため、第１の立設部３１と第２の立設部４２から配線が脱落しにくい。
Next, the operation of the battery module 10 of the present embodiment will be described.
When vibration or the like is applied to the battery module 10 and the wiring 61 tries to move, the third covering portion 24, the first standing portion 31, the second standing portion 42, the first extending portion 32, and the second The movement of the wiring 61 is suppressed by the extended portion 43. For this reason, the wiring is unlikely to drop off from the first standing portion 31 and the second standing portion 42.
また、配線６１が屈曲しているため、配線６１には、元の形状である直線状に復元しようとする力が働く。すると、配線６１と第１の立設部３１との間、配線６１と第２の立設部４２との間には、摩擦力が生じる。この摩擦力によって、配線６１が軸方向に移動しにくい。 Further, since the wiring 61 is bent, the wiring 61 is subjected to a force for restoring the original shape to a straight line. Then, a frictional force is generated between the wiring 61 and the first standing portion 31 and between the wiring 61 and the second standing portion 42. This frictional force makes it difficult for the wiring 61 to move in the axial direction.
したがって、上記実施形態によれば、以下のような効果を得ることができる。
（１）第１の立設部３１は、第３の被覆部２４の長手方向第１端部２４ａ側の面３１ａが配線６１と対向し、第２の立設部４２は、第３の被覆部２４の長手方向第２端部２４ｃ側の面４２ａが配線６１と対向している。このため、配線６１が、第３の被覆部２４の長手方向両端部のどちらに向けて移動しても、第１の立設部３１及び第２の立設部４２によって移動が規制され、第１の支持部３３及び第２の支持部４４から脱落しにくい。
Therefore, according to the above embodiment, the following effects can be obtained.
(1) The first standing portion 31 has a surface 31a on the first end portion 24a side in the longitudinal direction of the third covering portion 24 facing the wiring 61, and the second standing portion 42 has a third covering portion. A surface 42 a on the second end 24 c side in the longitudinal direction of the portion 24 faces the wiring 61. For this reason, even if the wiring 61 moves toward either of the longitudinal ends of the third covering portion 24, the movement is restricted by the first standing portion 31 and the second standing portion 42, It is difficult for the first support portion 33 and the second support portion 44 to fall off.
（２）第１の支持部３３及び第２の支持部４４は、電池ホルダ２１，４１に設けられている。電池ホルダ２１，４１に支持部３３，４４を設けることで、電池ホルダ２１，４１に電池セル１１に加えて、配線６１も保持させることができる。 (2) The first support portion 33 and the second support portion 44 are provided on the battery holders 21 and 41. By providing the support portions 33 and 44 on the battery holders 21 and 41, the battery holders 21 and 41 can hold the wiring 61 in addition to the battery cells 11.
（３）第１の立設部３１に第１の延設部３２を設けて、第２の立設部４２に第２の延設部４３を設けている。このため、第１の延設部３２及び第２の延設部４３によって、配線６１が、第３の被覆部２４の面３０と対向する方向に移動することが抑制される。このため、配線６１が脱落することが更に抑制される。 (3) The first extending portion 32 is provided in the first standing portion 31, and the second extending portion 43 is provided in the second standing portion 42. For this reason, the first extending portion 32 and the second extending portion 43 prevent the wiring 61 from moving in the direction facing the surface 30 of the third covering portion 24. For this reason, dropping off of the wiring 61 is further suppressed.
（４）配線６１は屈曲しているため、配線６１と第１の立設部３１との間及び配線６１と第２の立設部４２との間には摩擦力が生じ、配線６１が軸方向に移動することが抑制される。このため、配線６１と支持部３３，４４が擦れ合うことが抑制され、配線６１が破損しにくい。 (4) Since the wiring 61 is bent, a frictional force is generated between the wiring 61 and the first standing portion 31 and between the wiring 61 and the second standing portion 42, and the wiring 61 is pivoted. Moving in the direction is suppressed. For this reason, it is suppressed that the wiring 61 and the support parts 33 and 44 rub against each other, and the wiring 61 is hardly damaged.
