PURPOSE:To make it possible to perform the working for an electric equipment readily in a wide space, by a structure, in which assembling and removing works of a cooling unit, maintenance and inspection of the electric equipment and wiring working in a device box are carried out from the outside of a vehicle body. CONSTITUTION:A cover plate 28 is removed from an opening part 27, which if formed in the wall part of a closed chamber 6. Maintenance and inspection works are carried out through the opening part 27 from the outside of the lower part of a vehicle body 2. At this time, the workings can be performed readily and efficiently in the broad space at the outside of the vehicle body 1. The opening part 27 is opened and a closing plate 24, which is attached to a cooling unit 8, is removed from a patitioning wall 22. Then, assembling or removing working of the cooling unit 8 is performed with respect to an open chamber 5 through the opening part 27, the closed chamber 6 and an opening part 23 of the partitioning wall 22 from the outside at the lower part of the vehicle body 2. At this time, the closing plate 24 and an electric equipment 16, which is attached to the plate 24, are assembled and removed together with the cooling unit 8. This working can be also performed readily in the broad space. |
