The third side wall 23 and the fourth side wall 24 are perpendicular to the first side wall 21 and the second side wall 22. The external shape of the electric junction box 10 including the side walls 21 to 24 in a plan view is substantially rectangular. In a plan view, the first side wall 21 and the second side wall 22 are formed longer than the third side wall 23 and the fourth side wall 24. The fuse mounting portion 25 and the relay mounting portion 26 are provided between the first side wall 21 and the second side wall 22.
　第１側壁２１の外側面には、車体側の固定対象（例えばステー）に固定される第１固定部３１が形成されている。また、第２側壁２２の外側面には、車体側の固定対象（例えばステー）に固定される第２固定部３２が形成されている。第１固定部３１は、第１側壁２１に２つ設けられている。第２固定部３２は、第２側壁２２に２つ設けられている。各第１固定部３１と各第２固定部３２とは、第１側壁２１と第２側壁２２との対向方向Ｄにおいて、互いに対向する位置に設けられている。 A first fixing portion 31 to be fixed to a fixing target (for example, a stay) on the vehicle body side is formed on the outer surface of the first side wall 21. Further, a second fixing portion 32 to be fixed to a fixing target (for example, a stay) on the vehicle body side is formed on the outer surface of the second side wall 22. Two first fixing portions 31 are provided on the first side wall 21. Two second fixing portions 32 are provided on the second side wall 22. The first fixing portion 31 and the second fixing portion 32 are provided at positions facing each other in the facing direction D between the first side wall 21 and the second side wall 22.

Each second fixing portion 32 is formed so as to slightly project from the outer surface of the second side wall 22.
　第１固定部３１と第２固定部３２とは、車種などに応じて選択的に用いられる。すなわち、ある車種においては電気接続箱１０を第１固定部３１にて車体側に固定し、別の車種においては電気接続箱１０を第２固定部３２にて車体側に固定するようになっている。第１車種の車体側に電気接続箱１０を固定する場合には、当該第１車種の車体側にハウジング１１の第１固定部３１が固定されるが、第２固定部３２は当該第１車種の車体側に固定されず、例えば当該第１車種の車体と非接触であってよい。同様に、第１車種とは異なる第２車種の車体側に電気接続箱１０を固定する場合には、当該第２車種の車体側にハウジング１１の第２固定部３２が固定されるが、第１固定部３１は、当該第２車種の車体側に固定されず、例えば当該第２車種の車体と非接触であってよい。 The first fixed portion 31 and the second fixed portion 32 are selectively used according to the vehicle type and the like. That is, in one vehicle model, the electric junction box 10 is fixed to the vehicle body side by the first fixing portion 31, and in another vehicle model, the electric junction box 10 is fixed to the vehicle body side by the second fixing portion 32. There is. When the electric junction box 10 is fixed to the vehicle body side of the first vehicle model, the first fixing portion 31 of the housing 11 is fixed to the vehicle body side of the first vehicle model, but the second fixing portion 32 is the first vehicle model. It is not fixed to the vehicle body side of the vehicle, and may be non-contact with the vehicle body of the first vehicle type, for example. Similarly, when the electric junction box 10 is fixed to the vehicle body side of the second vehicle model different from the first vehicle model, the second fixing portion 32 of the housing 11 is fixed to the vehicle body side of the second vehicle model. The 1 fixing portion 31 is not fixed to the vehicle body side of the second vehicle model, and may be in non-contact with the vehicle body of the second vehicle model, for example.
　第１のリレー１３及び第２のリレー１４は、互いにサイズの異なる部品であり、第２のリレー１４よりも第１のリレー１３の方が大きい部品である。第１のリレー１３及び第２のリレー１４は、ヒューズ１２の重量よりも重い電気部品である。第１のリレー１３の重心位置１３ｇ及び第２のリレー１４の重心位置１４ｇが平面視で第１側壁２１と第２側壁２２との間の中心線ＣＬ上に位置するように、装着面２０における第１のリレー１３及び第２のリレー１４の配置位置が設定されている。 The first relay 13 and the second relay 14 are parts having different sizes from each other, and the first relay 13 is a larger part than the second relay 14. The first relay 13 and the second relay 14 are electrical components that are heavier than the weight of the fuse 12. On the mounting surface 20, the center of gravity position 13g of the first relay 13 and the center of gravity position 14g of the second relay 14 are located on the center line CL between the first side wall 21 and the second side wall 22 in a plan view. The arrangement positions of the first relay 13 and the second relay 14 are set.
　すなわち、第１側壁２１と第２側壁２２との対向方向Ｄにおいて、第１のリレー１３の重心位置１３ｇから第１側壁２１までの距離Ｗ１と、第１のリレー１３の重心位置１３ｇから第２側壁２２までの距離Ｗ２とが等しく設定されている。また同様に、第１側壁２１と第２側壁２２との対向方向Ｄにおいて、第２のリレー１４の重心位置１４ｇから第１側壁２１までの距離Ｗ３と、第２のリレー１４の重心位置１４ｇから第２側壁２２までの距離Ｗ４とが等しく設定されている。なお、第１側壁２１と第２側壁２２との対向方向Ｄは、第１及び第２側壁２１，２２と直交する方向であって、第３及び第４側壁２３，２４と平行な方向である。 That is, in the opposite direction D between the first side wall 21 and the second side wall 22, the distance W1 from the center of gravity position 13g of the first relay 13 to the first side wall 21 and the center of gravity position 13g of the first relay 13 to the second. The distance W2 to the side wall 22 is set to be equal. Similarly, in the opposite direction D between the first side wall 21 and the second side wall 22, the distance W3 from the center of gravity position 14g of the second relay 14 to the first side wall 21 and the center of gravity position 14g of the second relay 14 The distance W4 to the second side wall 22 is set to be equal. The facing direction D between the first side wall 21 and the second side wall 22 is a direction orthogonal to the first and second side walls 21 and 22, and a direction parallel to the third and fourth side walls 23 and 24. ..
　ハウジング１１において、第２のリレー１４が装着されたリレー装着部２６の対向方向Ｄの両側には、ヒューズ装着部２５がそれぞれ形成されている。すなわち、第２のリレー１４に対する第１側壁２１側の位置及び第２側壁２２側の位置の各々にヒューズ１２が配置されている。本実施形態の電気接続箱１０では、各ヒューズ１２及び各リレー１３，１４が前記中心線ＣＬに対して線対称に配置されている。 In the housing 11, fuse mounting portions 25 are formed on both sides of the relay mounting portion 26 on which the second relay 14 is mounted in the opposite direction D. That is, the fuse 12 is arranged at each of the position on the first side wall 21 side and the position on the second side wall 22 side with respect to the second relay 14. In the electrical junction box 10 of the present embodiment, the fuses 12 and the relays 13 and 14 are arranged line-symmetrically with respect to the center line CL.
　本実施形態の作用について説明する。 The operation of this embodiment will be described.
　上記構成を有する電気接続箱１０では、車体側に対し第１固定部３１で固定する場合と、第２固定部３２で固定する場合とで、固定部位から各リレー１３，１４の重心位置１３ｇ，１４ｇまでの距離が略変わらないようになっている。 In the electric junction box 10 having the above configuration, the center of gravity of each of the relays 13 and 14 is 13 g from the fixed portion, depending on whether the relay is fixed to the vehicle body side by the first fixing portion 31 or the second fixing portion 32. The distance up to 14g is almost the same.
　本実施形態の効果について説明する。 The effect of this embodiment will be described.
　（１）第１側壁２１と第２側壁２２との対向方向Ｄにおいて、第１のリレー１３の重心位置１３ｇから第１側壁２１までの距離Ｗ１と、第１のリレー１３の重心位置１３ｇから第２側壁２２までの距離Ｗ２とが等しく設定されている。また同様に、第１側壁２１と第２側壁２２との対向方向Ｄにおいて、第２のリレー１４の重心位置１４ｇから第１側壁２１までの距離Ｗ３と、第２のリレー１４の重心位置１４ｇから第２側壁２２までの距離Ｗ４とが等しく設定されている。 (1) In the opposite direction D between the first side wall 21 and the second side wall 22, the distance W1 from the center of gravity position 13g of the first relay 13 to the first side wall 21 and the center of gravity position 13g of the first relay 13 to the first. The distance W2 to the two side walls 22 is set to be equal. Similarly, in the opposite direction D between the first side wall 21 and the second side wall 22, the distance W3 from the center of gravity position 14g of the second relay 14 to the first side wall 21 and the center of gravity position 14g of the second relay 14 The distance W4 to the second side wall 22 is set to be equal.
　上記態様によれば、電気接続箱１０に装着される電気部品の中で重量物である各リレー１３，１４の重心位置１３ｇ，１４ｇが、第１側壁２１と第２側壁２２の間の中心位置（平面視で中心線ＣＬ上）に設定される。このため、電気接続箱１０を車体側に対して第１固定部３１で固定した場合と第２固定部３２で固定した場合の、固定部位から各リレー１３，１４の重心位置１３ｇ，１４ｇまでの距離の相違を小さく抑えることができる。従って、電気接続箱１０を車体側に対して第１固定部３１で固定した場合と第２固定部３２で固定した場合のいずれにおいても、電気接続箱１０の振動の増大を抑制することが可能となる。 According to the above aspect, the center-of-gravity positions 13g and 14g of the relays 13 and 14, which are heavy objects among the electric components mounted on the electric junction box 10, are at the center positions between the first side wall 21 and the second side wall 22. It is set to (on the center line CL in plan view). Therefore, when the electrical connection box 10 is fixed to the vehicle body side by the first fixing portion 31 and the second fixing portion 32, the positions of the centers of gravity of the relays 13 and 14 are 13 g and 14 g from the fixed portion. The difference in distance can be kept small. Therefore, it is possible to suppress an increase in vibration of the electric junction box 10 in both the case where the electric junction box 10 is fixed to the vehicle body side by the first fixing portion 31 and the case where the electric junction box 10 is fixed by the second fixing portion 32. It becomes.
　例えば、電気接続箱１０を第１固定部３１または第２固定部３２で車体に固定した状態では、電気接続箱１０のハウジング１１の底面が車体から離れて車体と直接接触せず、ハウジング１１が片持ち支持状態になることがある。このような状態においても、実施形態の電気接続箱１０は振動の増大を抑制することができる。この利点は、電気接続箱１０が二輪自動車に取り付けられる場合に一層顕著である。 For example, when the electrical junction box 10 is fixed to the vehicle body by the first fixing portion 31 or the second fixing portion 32, the bottom surface of the housing 11 of the electrical junction box 10 is separated from the vehicle body and does not come into direct contact with the vehicle body, and the housing 11 Cantilever support may occur. Even in such a state, the electrical junction box 10 of the embodiment can suppress an increase in vibration. This advantage is even more pronounced when the electrical junction box 10 is attached to a two-wheeled vehicle.
　（２）第２のリレー１４に対する第１側壁２１側の位置及び第２側壁２２側の位置の各々にヒューズ１２が配置されている。この態様によれば、第２のリレー１４を第１側壁２１と第２側壁２２の間の中心位置（平面視で中心線ＣＬ上）に配置しつつも、その第２のリレー１４の対向方向Ｄにおける両側（第１側壁２１側と第２側壁２２側）の領域にデッドスペースが生じないように構成することが可能となる。また、ヒューズ１２を第１側壁２１側と第２側壁２２側とに分散して配置することで、電気接続箱１０の温度上昇を小さく抑えることが可能となる。 (2) The fuse 12 is arranged at each of the position on the first side wall 21 side and the position on the second side wall 22 side with respect to the second relay 14. According to this aspect, the second relay 14 is arranged at the center position between the first side wall 21 and the second side wall 22 (on the center line CL in a plan view), but in the opposite direction of the second relay 14. It is possible to configure D so that no dead space is generated in the regions on both sides (the first side wall 21 side and the second side wall 22 side). Further, by arranging the fuses 12 dispersedly on the first side wall 21 side and the second side wall 22 side, it is possible to suppress the temperature rise of the electric junction box 10 to be small.
　本実施形態は、以下のように変更して実施することができる。本実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。 This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
　・上記実施形態の電気接続箱１０では、互いにサイズの異なる第１のリレー１３及び第２のリレー１４を備える構成としたが、これに特に限定されるものではない。例えば、図３に示すように、上記実施形態の第１のリレー１３に代えて、対向方向Ｄに並ぶ２つの第２のリレー１４を追加で備えた構成としてもよい。この例では、合計３つの同型のリレー１４が設けられている。それら３つのリレー１４からなるリレー群４０が、ヒューズ１２よりも重い第２電気部品を構成している。そして、各リレー１４の重心位置１４ｇから求められるリレー群４０の重心位置４０ｇが、第１側壁２１と第２側壁２２の間の中心位置（平面視で中心線ＣＬ上）に設定される。すなわち、第１側壁２１と第２側壁２２との対向方向Ｄにおいて、リレー群４０の重心位置４０ｇから第１側壁２１までの距離Ｗ５と、リレー群４０の重心位置４０ｇから第２側壁２２までの距離Ｗ６とが等しく設定されている。なお、同型（同質量）の３つのリレー１４からなるリレー群４０の重心位置４０ｇは、平面視において各リレー１４の重心位置１４ｇを直線で結んだ三角形の重心に設定される。 -The electrical junction box 10 of the above embodiment has a configuration in which the first relay 13 and the second relay 14 having different sizes are provided, but the present invention is not particularly limited to this. For example, as shown in FIG. 3, instead of the first relay 13 of the above embodiment, two second relays 14 arranged in the opposite direction D may be additionally provided. In this example, a total of three relays of the same type are provided. The relay group 40 including the three relays 14 constitutes a second electric component heavier than the fuse 12. Then, the center of gravity position 40g of the relay group 40 obtained from the center of gravity position 14g of each relay 14 is set at the center position between the first side wall 21 and the second side wall 22 (on the center line CL in a plan view). That is, in the opposite direction D between the first side wall 21 and the second side wall 22, the distance W5 from the center of gravity position 40 g of the relay group 40 to the first side wall 21 and the center of gravity position 40 g of the relay group 40 to the second side wall 22. The distance W6 is set to be equal. The center of gravity position 40g of the relay group 40 composed of three relays 14 of the same type (same mass) is set to the center of gravity of a triangle connecting the center of gravity positions 14g of each relay 14 with a straight line in a plan view.
　上記のような例によっても、上記実施形態と同様の効果を得ることができる。すなわち、電気接続箱１０を車体側に対して第１固定部３１で固定した場合と第２固定部３２で固定した場合の、固定部位からリレー群４０の重心位置４０ｇまでの距離の相違を小さく抑えることができる。従って、電気接続箱１０を車体側に対して第１固定部３１で固定した場合と第２固定部３２で固定した場合のいずれにおいても、電気接続箱１０の振動の増大を抑制することが可能となる。 The same effect as that of the above embodiment can be obtained by the above example. That is, the difference in the distance from the fixed portion to the center of gravity position 40 g of the relay group 40 is small when the electrical connection box 10 is fixed to the vehicle body side by the first fixing portion 31 and the second fixing portion 32. It can be suppressed. Therefore, it is possible to suppress an increase in vibration of the electric junction box 10 in both the case where the electric junction box 10 is fixed to the vehicle body side by the first fixing portion 31 and the case where the electric junction box 10 is fixed by the second fixing portion 32. It becomes.

　・第１固定部３１及び第２固定部３２の数などの構成は、上記実施形態に限定されるものではなく、電気接続箱１０の構成に応じて適宜変更してもよい。 The configuration such as the number of the first fixing portion 31 and the second fixing portion 32 is not limited to the above embodiment, and may be appropriately changed according to the configuration of the electrical connection box 10.
　・上記実施形態では、ヒューズ１２及びリレー１３，１４を備える電気接続箱１０に適用したが、ヒューズ１２及びリレー１３，１４以外の電気部品を備える電気接続箱にも適用可能である。 -In the above embodiment, it is applied to the electric junction box 10 including the fuse 12 and the relays 13 and 14, but it can also be applied to the electric junction box including the electric parts other than the fuse 12 and the relays 13 and 14.
