<p>Provided is a casing cover able to conform to the dimensional tolerance in a difference between levels of the casing. The casing cover (10) has an upper level cover (30) which covers openings (22A to 22C) in the upper level (14) of the casing (12), and a lower level cover (32) which covers an opening (22D) in the lower level (16) of the casing (12). Furthermore, among the upper level cover (30) and the lower level cover (32): one is formed with an insertion opening (36) passing therethrough in the direction of the height of the difference in levels; and the other is provided with a guide fitting (38) formed to a length (L2) in the direction of the height of the difference in levels, which is longer than the maximum allowable dimension (L0) of the height of the difference between levels plus a value (d), and inserted into the insertion opening (36). In addition, for purpose of preventing the guide fitting (38), which connects the upper level cover (30) and the lower level cover (32), from slipping out of the insertion opening (36), a connection fitting (40) is provided.</p> |
