According to such a configuration, for example, the rear protruding wall 8f is more likely to bend than the case where the thickness of the rear protruding wall 8f is the same as the thickness of the rear wall 8b, and thus the lower panel 7 and the upper panel 8 Assembling workability is easy to improve.

Further, in the present embodiment, for example, the thickness of the intermediate protruding wall 8g along the X direction is thinner than the thickness of the rear wall 8b and the front wall 8a along the X direction. According to such a configuration, for example, as compared with the case where the thickness of the intermediate projecting wall 8g is the same as the thickness of the rear wall 8b and the front wall 8a, the intermediate projecting wall 8g is more likely to bend, and thus engages with the engaging portion 8i. It is easier to engage (fit) with the joint portion 7i.

Further, in the present embodiment, for example, the thickness of the lateral wall 8c along the Z direction is thinner than the thickness of the rear wall 8b and the front wall 8a along the X direction. According to such a configuration, for example, the lateral wall 8c is more likely to bend than the case where the thickness of the lateral wall 8c is the same as the thickness of the rear wall 8b and the front wall 8a, and thus the engaging portion 8i and the engaging portion 7i Is even easier to engage (fit).
