CASING COVER

摘要

There is provided a casing cover that can accommodate a dimensional tolerance of a step on a casing. A casing cover 10 is provided with an upper step cover 30 which covers openings 22A to 22C in an upper step surface 14 of a casing 12 and a lower step cover 32 which covers an opening 22D in a lower step surface 16 of the casing 12. In addition, an insertion opening 36 penetrating in the step height direction is formed in one of the upper step cover 30 and the lower step cover 32, while a guiding member 38 configured to be inserted into the insertion opening 36 and have a length L2 in the step height direction longer than a maximum permissible size value L0+d of the step height is provided in another one of the upper step cover 30 and the lower step cover 32. Further, there is provided a connecting member 40 which connects the upper step cover 30 to the lower step cover 32 to thereby prevent the guiding member 38 from falling out from the insertion opening 36.
