Abstract
An apparatus for retractably tilting a visor of a door mirror of a motor vehicle between a normal position and a retracted position, including a spring member made of shape-memory alloy, a lever member for setting the spring member at a minimum mounting length and a maximum mounting length when the visor is disposed at one of and the other one of the normal position and the retracted position, respectively, and a battery acting as a power source of the apparatus, whereby when the spring member is heated upon its energization, the spring member is contracted from the maximum mounting length to the minimum mounting length based on shape-memory effect of the shape-memory alloy such that the visor is tilted to one of the normal position and the retracted position.
