Accordingly, the movable parts of the sub-board case main body 121 and the sub-board case lid 171 can be welded, so that the sub-board case main body 121 and the sub-board case lid 171 can be firmly welded and coupled.

  The sub-board case main body 121 includes a first main body side slide engaging portion 137 and a second main body side slide engaging portion 147 formed on the outside of the first side wall portion 132 and the second side wall portion 142, The sub-board case lid 171 includes a first lid side slide engagement portion 184 and a second lid side slide engagement portion 194, a first lid side slide engagement portion 184, a second lid side slide engagement portion 194, and It has a first side cover portion 182 and a second side cover portion 192 that cover the first main body side slide engaging portion 137 and the second main body side slide engaging portion 147. As a result, the first main body side welded portion 133 and the second main body side welded portion 143 are blocked by the first side cover portion 182 and the second side cover portion 192 and the like. Unauthorized access to the welded part 143 can be prevented. Therefore, unauthorized opening of the sub board case 120 can be prevented, and unauthorized actions can be prevented.

  Further, a case side welded portion 167 that can be welded to the connector cover 261 is formed on the fourth side wall portion 162, and a cover side welded portion 265 that can be welded to the case side welded portion 167 is formed on the connector cover 261. Thereby, the connector cover 261 can be welded to the sub-board case main body 121.

[Third characteristic configuration of sub-control device]
In the first embodiment, the third main body-side welded portion 153 and the third lid-side welded portion 203 are curved surfaces that extend along the side end portions of the sub-board case main body 121 and the sub-board case lid 171 while being welded to each other. The welding surface (third main body side welding surface 156 and third lid side welding surface 206) of the third main body side welding portion 153 and the third lid side welding portion 203 has a curved surface shape (main body side). The curved surface portion 154 and the lid-side curved surface portion 204) are formed so as to be bent and inclined in a “<” shape with respect to the extending direction. This complicates the shapes of the third main body side welded portion 153 and the third lid side welded portion 203, making it difficult to duplicate the sub substrate case main body 121 and the sub substrate case cover 171. Therefore, after destroying at least one of the sub-board case main body 121 and the sub-board case lid 171 and illegally opening the sub-board case 120, it is difficult to replace the damaged parts with replicas and restore them. Therefore, unauthorized opening of the sub-board case 120 can be prevented, and unauthorized actions can be prevented.

  Further, the curved surface shape (the main body side curved surface portion 154 and the lid side curved surface portion 204) is formed such that the curvature continuously changes along a direction substantially perpendicular to the extending direction of the curved surface shape. This complicates the shapes of the third main body side welded portion 153 and the third lid side welded portion 203, making it difficult to duplicate the sub substrate case main body 121 and the sub substrate case cover 171. Therefore, after destroying at least one of the sub-board case main body 121 and the sub-board case lid 171 and illegally opening the sub-board case 120, it is difficult to replace the broken parts with replicas and restore them. Therefore, unauthorized opening of the sub-board case 120 can be prevented, and unauthorized actions can be prevented.

  The sub-board case cover 171 is coupled to the sub-board case body 121 so that the sub-board case cover 171 can be attached to and detached from the sub-board case body 121 and the sub-board case cover 171 covers the opening 121a. The sub-board case lid 171 can be moved relative to the sub-board case main body 121 in a direction substantially perpendicular to the extending direction of the curved surface shape (the main body-side curved surface portion 154 and the lid-side curved surface portion 204). The third main body side welded portion 153 and the third lid side welded portion 203 are configured to be capable of being welded in a state in which the relative movement is moved to the coupling position. Accordingly, the sub-board case main body 121 and the sub-board case lid 171 can be easily welded and combined while complicating the shapes of the third main body-side welded portion 153 and the third lid-side welded portion 203.

[Fourth Characteristic Configuration of Sub-Control Device]
In the first embodiment, the third main body-side welded portion 153 and the third lid-side welded portion 203 are curved surfaces that extend along the side end portions of the sub-board case main body 121 and the sub-board case lid 171 while being welded to each other. The first identification mark 221 and the second identification mark 222 are formed across the third main body side welded portion 153 and the third lid side welded portion 203. Accordingly, the first identification mark 221 and the second identification mark 222 need to be formed so as to be aligned with the third main body side welding portion 153 and the third lid side welding portion 203, respectively. Duplication of the main body 121 and the sub-board case lid 171 becomes difficult. Therefore, after destroying at least one of the sub-board case main body 121 and the sub-board case lid 171 and illegally opening the sub-board case 120, it is difficult to replace the damaged parts with replicas and restore them. Therefore, unauthorized opening of the sub-board case 120 can be prevented, and unauthorized actions can be prevented.

  Further, the curved surface shape (the main body side curved surface portion 154 and the lid side curved surface portion 204) is formed such that the curvature continuously changes along a direction substantially perpendicular to the extending direction of the curved surface shape. This complicates the shapes of the third main body side welded portion 153 and the third lid side welded portion 203, making it difficult to duplicate the sub substrate case main body 121 and the sub substrate case cover 171. Therefore, after destroying at least one of the sub-board case main body 121 and the sub-board case lid 171 and illegally opening the sub-board case 120, it is difficult to replace the broken parts with replicas and restore them. Therefore, unauthorized opening of the sub-board case 120 can be prevented, and unauthorized actions can be prevented.

  The sub-board case cover 171 is coupled to the sub-board case body 121 so that the sub-board case cover 171 can be attached to and detached from the sub-board case body 121 and the sub-board case cover 171 covers the opening 121a.

The third main body side welded portion 153 and the third lid side welded portion 203 are configured to be able to come into contact with each other in a state of relative movement to the coupling position. Accordingly, the sub-board case main body 121 and the sub-board case lid 171 can be easily coupled while making the shapes of the third main body-side welded portion 153 and the third lid-side welded portion 203 complicated.

  Further, the contact surfaces (the third main body side welding surface 156 and the third lid side welding surface 206) of the third main body side welding portion 153 and the third lid side welding portion 203 are curved (the main body side curved surface portion 154 and The lid-side curved surface portion 204) is formed so as to be bent and inclined in a "<" shape with respect to the extending direction. This complicates the shapes of the third main body side welded portion 153 and the third lid side welded portion 203, making it difficult to duplicate the sub substrate case main body 121 and the sub substrate case cover 171. Therefore, after destroying at least one of the sub-board case main body 121 and the sub-board case lid 171 and illegally opening the sub-board case 120, it is difficult to replace the damaged parts with replicas and restore them. Therefore, unauthorized opening of the sub-board case 120 can be prevented, and unauthorized actions can be prevented.

  The sub-board case main body 121 and the sub-board case lid 171 are formed using a transparent resin material, and the first identification mark 221 and the second identification mark 222 are connected to the third main body side welded portion 153 by internal marking. It is formed across the third lid side welded portion 203. As a result, the first identification mark 221 and the second identification mark 222 are formed so as to be shifted from the substantially flat surface in the thickness direction of the sub-board case main body 121 and the sub-board case lid 171 (so as to wave in a curved surface). Therefore, it is difficult to imitate the first identification mark 221 and the second identification mark 222 formed inside the third main body side welded portion 153 and the third lid side welded portion 203. 121 and the sub-board case lid 171 are difficult to replicate. Therefore, after destroying at least one of the sub-board case main body 121 and the sub-board case lid 171 and illegally opening the sub-board case 120, it is difficult to replace the damaged parts with replicas and restore them. Therefore, unauthorized opening of the sub-board case 120 can be prevented, and unauthorized actions can be prevented.

  Further, the third main body side welded portion 153 and the third lid side welded portion 203 are welded in a state of being in contact with each other. As a result, the sub-board case 120 cannot be opened unless the welded portion between the third main body-side weld portion 153 and the third lid-side weld portion 203 is destroyed. Can prevent fraud.
