Drive apparatus and lens drive apparatus |
摘要 |
A drive apparatus having: a shape memory alloy having a property such that a temperature transformation sensitivity in a temperature range from a starting point of austenite transformation (As) at a predetermined stress to an end point of austenite (Af) is higher than a temperature transformation sensitivity in other temperature range, and a temperature transformation sensitivity in a temperature range from a starting point of martensite transformation (Ms) at a predetermined stress to an end point of martensite transformation (Mf) is higher than a temperature transformation sensitivity in other temperature range; and a driven member which is moved by a transformation of the shape memory alloy; wherein the driven member is moved in a temperature range of higher temperature transformation sensitivity.
