With this configuration, the electrical connection box 1 and the wire harness WH can protect the electronic component 4 provided on the mounting portion 21 by the covering portion 31 of the lid member 3. At this time, when the electric connection box 1 and the wire harness WH insert the locking protrusion 32 of the lid member 3 into the locking recess 22 of the main body 2, first, the pair of rib wall portions 24 on the main body 2 side Is inserted into the lid member 3 along the first width direction X through the insertion opening 36, and is in contact with the pair of guide wall portions 34, respectively. With this configuration, the electric connection box 1 and the wire harness WH bring the lid member 3 in the first width direction X with respect to the main body portion 2 while bringing the pair of guide wall portions 34 into contact with the pair of rib wall portions 24, respectively. It can be relatively moved toward the locking recess 22 side along the line. As a result, the electric connection box 1 and the wire harness WH guide the pair of guide wall portions 34 along the first width direction X by the pair of rib wall portions 24, and guide the locking projection portion 32 of the lid member 3 to the main body portion. It can be inserted into the locking recess 22 of 2 and locked. Therefore, the electrical connection box 1 and the wire harness WH can improve the assembling workability when assembling the lid member 3 to the main body 2.

ここでは、本体部２は、例えば、図１に示すように、係止凹部２２側が閉塞し本体側係止部２３側に開口部ＯＰが設けられた閉塞空間部ＳＰ内に据え付けられる。電気接続箱１、ワイヤハーネスＷＨは、このような場合であっても上記のように一対のリブ壁部２４によって一対のガイド壁部３４を第１幅方向Ｘに沿って案内しながら係止突起部３２を係止凹部２２に挿入し係止することができる。この結果、電気接続箱１、ワイヤハーネスＷＨは、例えば、係止凹部２２を目視できないような場合であっても容易に係止突起部３２を係止凹部２２に挿入し係止することができるので、このような場合に顕著に組み付け作業性の向上を図ることができる。 Here, for example, as shown in FIG. 1, the main body portion 2 is installed in a closed space portion SP in which the locking recess 22 side is closed and the opening OP is provided on the main body side locking portion 23 side. Even in such a case, the electric junction box 1 and the wire harness WH have a locking projection while guiding the pair of guide wall portions 34 along the first width direction X by the pair of rib wall portions 24 as described above. The portion 32 can be inserted into the locking recess 22 and locked.

以上で説明した挿通開口部３６は、以上で説明した形状に限られない。例えば、図１２の変形例に係る蓋部材３Ａは、挿通開口部３６にかえて挿通開口部３６Ａを有する。挿通開口部３６Ａは、挿通開口部３６と同様に端部壁部３５Ａ側の端部に設けられる。挿通開口部３６Ａは、リブ壁部２４をガイド壁部３４に隣接させて第１幅方向Ｘに沿って挿通可能とする開口である。挿通開口部３６Ａは、端部壁部３５Ａの高さ方向Ｚの下側に設けられる。ここでは、挿通開口部３６Ａは、ガイド壁部３４Ａに隣接して１つ、ガイド壁部３４Ｂに隣接して１つ、合計２つが別個に設けられている。一方の挿通開口部３６Ａは、第１幅方向Ｘにおいて、ガイド壁部３４Ａのガイド壁部３４Ｂ側、すなわち、内側に形成される。同様に、他方の挿通開口部３６Ａは、第１幅方向Ｘにおいて、ガイド壁部３４Ｂのガイド壁部３４Ａ側、すなわち、内側に形成される。ここでは、端部壁部３５Ａは、２つの挿通開口部３６Ａ以外の部分の高さ方向Ｚの下端がガイド壁部３４Ａ、３４Ｂの高さ方向Ｚの下端とほぼ揃っている。この構成により、一方の挿通開口部３６Ａは、ガイド壁部３４Ａの内側にリブ壁部２４Ａを第１幅方向Ｘに沿って挿通可能とし、他方の挿通開口部３６Ａは、ガイド壁部３４Ｂの内側にリブ壁部２４Ｂを第１幅方向Ｘに沿って挿通可能とする。この場合も、一対のリブ壁部２４は、各挿通開口部３６Ａを介して第１幅方向Ｘに沿って挿通された状態で、一対のガイド壁部３４に挟まれて位置する。この場合であっても、電気接続箱１、ワイヤハーネスＷＨは、上記と同様に組み付け作業性を向上することができる。 The insertion opening 36 described above is not limited to the shape described above. For example, the lid member 3A according to the modified example of FIG. 12 has an insertion opening 36A instead of the insertion opening 36. The insertion opening 36A is provided at the end on the end wall portion 35A side in the same manner as the insertion opening 36. The insertion opening 36A is an opening in which the rib wall portion 24 is adjacent to the guide wall portion 34 so that the rib wall portion 24 can be inserted along the first width direction X. The insertion opening 36A is provided below the end wall portion 35A in the height direction Z. Here, a total of two insertion openings 36A are separately provided, one adjacent to the guide wall portion 34A and one adjacent to the guide wall portion 34B. One of the insertion openings 36A is formed on the guide wall portion 34B side of the guide wall portion 34A, that is, inside, in the first width direction X. Similarly, the other insertion opening 36A is formed on the guide wall portion 34A side, that is, inside of the guide wall portion 34B in the first width direction X. Here, in the end wall portion 35A, the lower ends of the portions other than the two insertion openings 36A in the height direction Z are substantially aligned with the lower ends of the guide wall portions 34A and 34B in the height direction Z. With this configuration, one insertion opening 36A allows the rib wall portion 24A to be inserted inside the guide wall portion 34A along the first width direction X, and the other insertion opening 36A is inside the guide wall portion 34B. The rib wall portion 24B can be inserted along the first width direction X. Also in this case, the pair of rib wall portions 24 are sandwiched between the pair of guide wall portions 34 in a state of being inserted along the first width direction X through the respective insertion openings 36A. Even in this case, the electrical connection box 1 and the wire harness WH can improve the assembly workability in the same manner as described above.

また、図１３の変形例に係る蓋部材３Ｂは、挿通開口部３６、３６Ａにかえて挿通開口部３６Ｂを有する。挿通開口部３６Ｂは、挿通開口部３６、３６Ａと同様に端部壁部３５Ａ側の端部に設けられる。挿通開口部３６Ｂは、リブ壁部２４をガイド壁部３４に隣接させて第１幅方向Ｘに沿って挿通可能とする開口である。挿通開口部３６Ｂは、端部壁部３５Ａの高さ方向Ｚの下側に設けられる。挿通開口部３６Ｂは、挿通開口部３６Ａと同様に、ガイド壁部３４Ａに隣接して１つ、ガイド壁部３４Ｂに隣接して１つ、合計２つが別個に設けられている。ここでは、一方の挿通開口部３６Ｂは、第１幅方向Ｘにおいて、ガイド壁部３４Ａのガイド壁部３４Ｂ側とは反対側、すなわち、外側に形成される。同様に、他方の挿通開口部３６Ｂは、第１幅方向Ｘにおいて、ガイド壁部３４Ｂのガイド壁部３４Ａとは反対側、すなわち、外側に形成される。ここでは、端部壁部３５Ａは、全体の高さ方向Ｚの下端がガイド壁部３４Ａ、３４Ｂの高さ方向Ｚの下端とほぼ揃っている。この構成により、一方の挿通開口部３６Ｂは、ガイド壁部３４Ａの外側にリブ壁部２４Ａを第１幅方向Ｘに沿って挿通可能とし、他方の挿通開口部３６Ｂは、ガイド壁部３４Ｂの外側にリブ壁部２４Ｂを第１幅方向Ｘに沿って挿通可能とする。この場合は、一対のリブ壁部２４は、各挿通開口部３６Ｂを介して第１幅方向Ｘに沿って挿通された状態で、第２幅方向Ｙに対して一対のガイド壁部３４の外側に位置する。言い換えれば、一対のガイド壁部３４は、一対のリブ壁部２４に挟まれて位置する。さらに言い換えれば、一対のガイド壁部３４は、第２幅方向Ｙに対して一対のリブ壁部２４の間に位置する。この場合であっても、電気接続箱１、ワイヤハーネスＷＨは、上記と同様に組み付け作業性を向上することができる。また、挿通開口部は、例えば、１つの挿通開口部３６Ａと１つの挿通開口部３６Ｂとを組み合わせたものであってもよい。 Further, the lid member 3B according to the modified example of FIG. 13 has an insertion opening 36B instead of the insertion openings 36 and 36A.

The insertion opening 36B is provided below the end wall portion 35A in the height direction Z. Similar to the insertion opening 36A, the insertion opening 36B is provided separately with one adjacent to the guide wall portion 34A and one adjacent to the guide wall portion 34B, for a total of two. Here, one insertion opening 36B is formed in the first width direction X on the side opposite to the guide wall portion 34B side of the guide wall portion 34A, that is, on the outer side. Similarly, the other insertion opening 36B is formed in the first width direction X on the opposite side of the guide wall portion 34B from the guide wall portion 34A, that is, on the outer side. Here, in the end wall portion 35A, the lower end of the entire height direction Z is substantially aligned with the lower end of the guide wall portions 34A and 34B in the height direction Z. With this configuration, one insertion opening 36B allows the rib wall portion 24A to be inserted outside the guide wall portion 34A along the first width direction X, and the other insertion opening 36B is outside the guide wall portion 34B. The rib wall portion 24B can be inserted along the first width direction X. In this case, the pair of rib wall portions 24 are inserted along the first width direction X through the respective insertion openings 36B, and are outside the pair of guide wall portions 34 with respect to the second width direction Y. Located in. In other words, the pair of guide wall portions 34 are located sandwiched between the pair of rib wall portions 24. In other words, the pair of guide wall portions 34 are located between the pair of rib wall portions 24 in the second width direction Y. Even in this case, the electrical connection box 1 and the wire harness WH can improve the assembly workability in the same manner as described above. Further, the insertion opening may be, for example, a combination of one insertion opening 36A and one insertion opening 36B.
