The bottom plate section (44), the top plate section (42) and the front plate section (40) define a space (20a) facing the opening (2b). The space (20a) and a pair of vertical passages (20b) arranged laterally define a substantially H-shaped ventilation passage. The base section (25) and the front plate section (40) are formed independently.</p> |
