Claims

[Scope of utility model registration request]

A support board screwed to the inner bottom wall of the chassis in a mounted state, and a gland provided at the edge of the circuit board planted on this support board and whose upper end is screwed to the outer peripheral top wall of the chassis. A cover and a spring plate for press-contacting the free end of the ground cover to the inner bottom wall of the chassis are fixed on the inner bottom wall, and the tip protrusion of the spring plate is attached to the spring plate in the attached and fixed state. An electronic device housing characterized in that a free end of the ground cover is integrally provided with a protruding claw that engages with the inner bottom wall of the chassis for constantly abutting against the inner bottom wall of the chassis.
