Thus, in this embodiment, since the cover main body 11 and the lid | cover 17 were locked to the united state using fitting part 15A, 15B, compared with the case where a locking part is provided separately from a fitting part. It is possible to simplify the shape of the cover main body 11.

  Further, the fitting portions 15A and 15B are configured to penetrate the lid 17 in a state where the cover body 11 and the lid 17 are combined, but in this way, the protruding dimensions of the fitting portions 15A and 15B are lengthened. When the fitting allowance with the terminal fittings 30A and 30B is secured to a large extent, the protruding end portions of the fitting portions 15A and 15B that pass through the lid 17 and are exposed to the outer surface side of the lid 17 are damaged by interference of other members. There is concern. Therefore, in the present embodiment, the lid 17 is configured to protrude to the outer surface side of the lid 17 and surrounds the protruding end portions of the fitting portions 15A and 15B in a state where the cover body 11 and the lid 17 are combined. 18A and 18B are formed. According to this configuration, since the protruding end portions of the fitting portions 15A and 15B are protected by the cylindrical portions 18A and 18B, the fitting portion 15A is avoided while avoiding damage to the protruding end portions of the fitting portions 15A and 15B. , 15B and the terminal fittings 30A, 30B can be secured with a large margin.
