Abstract
A spigot type breakaway mirror (10) for automobile exterior use includes both a supporting base (11) and a mirror subassembly (16), the base (11) having an upstanding spigot (12) which has a curved constraining surface (13), and the mirror subassembly (11) is provided with a locating surface (17) engageable over constraining surface (13) which constrains pivotal movement of the mirror subassembly to be about the spigot, but there are provided a cam pad (23) and recess surface (24) on the base and mirror subassembly respectively, and a spring (20) which cooperates between the base and mirror subassembly to retain the cam and recess surfaces in engagement, but the cam pad (23) and recess (24) surfaces cause the mirror subassembly (16) to cam outwardly away from the supporting base (11) if the mirror subassembly is caused to deflect upon striking an obstruction.
