Further, by making the side edge portion of the lid engaging with the lid engaging portion a U-shaped vertical section, the holding elastic pressure engaging force of the lid side edge portion by the lid engaging portion is increased, and the lid engaging portion is engaged. Highly reliable lid that secures the necessary attachment strength of the lid and reliably prevents accidental disengagement of the lid, even if the locking state of the lid and the side edge of the lid is slightly loose. A mounting structure can be provided.
