また、図６に示すように、バッテリ端子３２の取付け／取外し等に必要な工具スペースまでしか開閉用カバー１５を開かないため、ヒンジ部１４への負担が非常に少なくて済む。さらに、ヒューズユニット２０のヒューズハウジング２１の側面２１ａの開閉用カバー１５のロック用凸部１６の開閉軌跡２４上に溝状凹部２３を形成し、開閉用カバー１５はロック用凸部１６に面取り加工を入れるのみで、仮係止機能を持たせることができるため、金型コストを抑え、樹脂成形の生産性にも影響の少ない形状となっており、その分、製造の低コスト化を図ることができる。   Further, as shown in FIG. 6, since the opening / closing cover 15 is opened only to the tool space necessary for attachment / detachment of the battery terminal 32, the burden on the hinge portion 14 can be very small. Further, a groove-like recess 23 is formed on the opening / closing locus 24 of the locking projection 16 of the opening / closing cover 15 on the side surface 21 a of the fuse housing 21 of the fuse unit 20, and the opening / closing cover 15 is chamfered into the locking projection 16. Since it is possible to provide a temporary locking function simply by putting in, the mold cost is reduced, and the shape is less affected by resin molding productivity. Can do.

さらに、作業終了後に開閉用カバー１５を閉じる際には、ロック用凸部１６の溝状凹部２３に引っ掛からない部分に傾斜面部１６ｂ，１６ｃを形成したことにより、ヒューズユニット２０の側面２１ａに引っ掛かっても容易に乗り越えることができる。これにより、ロック用凸部１６の角部１６ａがヒューズユニット２０のヒューズハウジング２１の側面２１ａの下端縁部２１ｂに本係止されて全閉状態が保持される。   Further, when closing the opening / closing cover 15 after the work is finished, the inclined surface portions 16b and 16c are formed in the portions that are not hooked by the groove-like concave portion 23 of the locking convex portion 16, so that they are hooked on the side surface 21a of the fuse unit 20. Can easily get over. As a result, the corner portion 16a of the locking convex portion 16 is finally locked to the lower end edge portion 21b of the side surface 21a of the fuse housing 21 of the fuse unit 20, and the fully closed state is maintained.

また、ヒューズハウジング２１の側面２１ａにおける溝状凹部２３の形成位置と開閉用カバー１５の側壁１５ｂの内面における開閉用カバー１５のロック用凸部１６の形成位置を開閉用カバー１５のロック用凸部１６の開閉軌跡２４上において適宜調整することで、溝状凹部２３に対する開閉用カバー１５のロック用凸部１６の角部１６ａの仮係止位置を可変させて、開閉用カバー１５の開閉角度を任意の所定角度に調整することができる。これにより、開閉用カバー１５の開角度を所望する任意の所定角度に簡単かつ確実に可変させることができ、バッテリ端子３２の取付け／取外し等の作業に最適な角度に開閉用カバー１５の開角度を設定することができる。   Further, the position where the groove-like concave portion 23 is formed on the side surface 21 a of the fuse housing 21 and the position where the locking convex portion 16 of the opening / closing cover 15 is formed on the inner surface of the side wall 15 b of the opening / closing cover 15 are the locking convex portions of the opening / closing cover 15. The opening / closing angle of the opening / closing cover 15 is varied by appropriately adjusting the opening / closing locus 24 of the opening / closing path 24 so that the temporary locking position of the corner 16a of the locking projection 16 of the opening / closing cover 15 with respect to the groove-like recess 23 is varied. It can be adjusted to any predetermined angle. As a result, the opening angle of the opening / closing cover 15 can be easily and reliably varied to a desired desired angle, and the opening angle of the opening / closing cover 15 is set to an optimum angle for work such as attachment / detachment of the battery terminal 32. Can be set.

さらに、開閉用カバー１５の上壁１５ａの両側壁１５ｂ，１５ｂの各内面に突出したロック用凸部１６に相対向する位置には、ロック用凸部１６を樹脂で一体成形する際に加工抜き孔１７が形成され、この加工抜き孔１７から水がヒューズユニット２０のヒューズハウジング２１の可溶体収容部２２内に浸入するが、可溶体収容部２２の底面にはヒューズハウジング２１の側面２１ａに連通する水抜き孔２２ｂが形成されているため、この水抜き孔２２ｂより浸入した水を外部へ排出することができる。これにより、ヒューズユニット２０に水が溜まることがなく、水溜まりによる電源供給用の電線等の電線の腐食やバスバー２５と可溶体２６の導通板部２７の腐食及び回路ショート等の故障、トラブルを簡単かつ確実に防止することができる。   Further, when the locking convex portion 16 is integrally formed with resin, it is removed at a position opposite to the locking convex portion 16 protruding from the inner surfaces of the both side walls 15b, 15b of the upper wall 15a of the opening / closing cover 15. A hole 17 is formed, and water penetrates into the fusible body accommodating portion 22 of the fuse housing 21 of the fuse unit 20 from the processed hole 17, and the bottom surface of the fusible body accommodating portion 22 communicates with the side surface 21 a of the fuse housing 21. Since the drain hole 22b to be formed is formed, the water that has entered through the drain hole 22b can be discharged to the outside. As a result, water does not collect in the fuse unit 20, and troubles and troubles such as corrosion of electric wires such as electric power supply wires due to the water accumulation, corrosion of the conductive plate portion 27 of the bus bar 25 and the fusible body 26, and circuit shorting can be easily performed. And it can prevent reliably.
