Claims

[Scope of utility model registration request]

It consists of a main body case and a cover that covers a part of the main body case, and when the cover is closed, the outer peripheral lower end surface of the cover and the outer peripheral upper surface of the main body case are opposed with a predetermined gap, and the cover is closed. In the opening/closing structure of the cover, in which the opening/closing fulcrum member fits into the fulcrum receiver of the main case and opens and closes by rotating around the opening/closing fulcrum, the arc drawn by the rotation locus provided on a part of the fulcrum member of the cover. An opening/closing operation guide protrusion is installed on the opening/closing operation guide wall connecting the inside and the main body case at a position that slides into engagement with the opening/closing operation guide wall, and a fulcrum guide groove is installed at a position where the fulcrum of the cover is located. The opening/closing structure of the cover.
