dust shield
Debris deflection cover
A dust shield is a protective cover that prevents dust and debris from entering a mechanism or contaminating a surface.
In automotive contexts, it's typically a metal plate behind a brake rotor that keeps road grit away from brake components: The rusted dust shield was scraping against the rotor.
Similar shields protect camera sensors, industrial equipment, and electronic devices.
