Claims

[Scope of utility model registration request]

In the grommet, the grommet has a thick peripheral wall portion that is fitted into a notch provided in the case, and a tube that is connected to one of the thick peripheral wall portions and seals an electric wire inserted therein. A bendable and deformable thin part is provided on the notch fitting surface of the case, and when the thick peripheral wall part is fitted into the notch of the case, the above-mentioned part abuts against the protrusion provided in the notch. A waterproof structure of a grommet, characterized in that a thin wall part is elastically deformed and comes into close contact with the protrusion.
