Claims

[Scope of utility model registration request]

A case having an opening formed at one end and housing electronic components constituting an electrical unit inside, and a lid for closing the opening of the case, and an electric wire for electrically connecting the lid to an external device. In the structure of an electrical equipment unit case including a rubber grommet for penetrating the case, a gasket fitting groove into which a gasket fits is formed around the entire periphery of the opening of the case, and a gasket fitting groove is fitted into the gasket fitting groove. A fitting gasket is formed integrally with the grommet, and when the lid is engaged with the opening of the case, the gasket is elastically deformed by pressure between the lid and the case in the gasket fitting groove, and the lid and the gasket are elastically deformed by pressure between the lid and the case. A waterproof structure for the electrical unit case that maintains airtightness between the case and the case.
