In the shield lid, a tongue piece bent at an angle of approximately 90 degrees is formed on the inside of the chassis frame, a hole is formed in the tongue piece, and both sides of the upper surface of the shield wall are attached to the chassis frame side. A double shield wall is formed which is bent inward, an insertion hole is formed in the upper surface of the shield wall for inserting the tongue piece, and a convex portion is formed on one side of the double wall of the shield wall, and a convex portion is placed on the other side at a corresponding position. A tuner characterized in that the shield lid is fixed to the chassis frame by forming recesses, inserting the tongue pieces into the insertion holes on the upper surface of the shield wall, and fitting the holes of the tongue pieces into the recesses and protrusions. chassis structure.
