いう不具合があった。However, in the case of resin having the above-mentioned general structure, distortion occurs when the case is formed. For example, in the case of the resin case having a small thickness, inward deformation as shown in FIG. 8 is likely to occur during the resin molding, particularly on the relatively long side wall surface of the resin case. In a resin case in which the housing member 1 and the cover member 2 make a pair, when these distortions are caused, when the cover member 2 is to be attached to the housing member 1, the housing member 1 and the cover member 2 The fitting workability is poor. That is, the relatively long side wall 1 constituting the container 1
In A and 1C, for example, block members such as relays and fuses are densely housed in the casing member 1,
As shown in FIG. 8, with respect to the container 1 in which the side walls 1A and 1C are maintained linearly so as not to cause distortion,
When the cover member 2 which is the side wall 2A curved inward is to be attached, the opening edge (upper side edge) of the side wall 1A of the container member 1 and the opening side edge of the curved side wall 2A of the cover member 2 abut. (Collision) (see FIG. 9), which caused a problem that the operation of attaching the lid member 2 on the container 1 was difficult to perform smoothly.

The cost of the resin material or the molding cost of the mold is high, which is difficult to implement in terms of economy. In some cases, the deposition itself became difficult.

嵌入させることが円滑になされるものである。The feature of this embodiment is that the container 1
1 is formed on the upper side edge (opening side edge) of the front wall 13A, and V-shaped inclined edges 20 which are inclined toward the bottom plate 12 along the center from both side ends of the side edge. According to this configuration, as described above, it becomes easy to attach the lid member 16 having the front wall 18A having the curved distortion to the casing member 11. That is, since the V-shaped inclined edge 20 is formed on the front wall 13A of the casing member 11, the following operation is performed. That is, as shown in FIG. 4, after the locking piece 19B provided on the lid member 16 is locked to the locking claw 14B provided on the container member 11, the locking member is used as an axis for the locking point. The cover member 16 is rotated so that the inner surface of the front wall 18A of the housing 16 overlaps the outer surface of the front wall 13A of the housing member 11. By this operation, both ends of the front wall 18A of the lid member 16 to be attached on the housing member 11, that is, the inner surfaces on both side ends of the front wall 18A having almost no distortion are firstly attached to the housing member 11. Front wall 13A
(See FIG. 5). Further, the lid member 16 is attached to the container member 11.
The edge of the front wall 18 </ b> A of the lid member 16 is provided on the housing member 11 as the cover member 16 is turned in the covering direction.
The lid member 16 is gradually fitted into the casing member 11 while sliding on the upper edge of 3A. At this time, the inward bending distortion generated in the lid member 16 is pushed and spread by the front wall 13A of the casing member 11. Therefore, the lid member 16 is smoothly fitted into the casing member 11.

However, the present invention is not limited to this. For example, the V-shaped inclined edge 20 is provided at the opening edge of the front wall 18A having the curved distortion of the lid member 16 so as to be inclined toward the top plate 17 and the front wall 13A of the casing member 11 is formed. Even if the opening edge is formed in a straight line, the same effect as described above can be obtained. Further, the V-shaped inclined edge 20 may have an arc shape.
