PROBLEM TO BE SOLVED: To provide a displacement mechanism capable of obtaining a large curvature angle using small displacement of a shape memory alloy wire.SOLUTION: A displacement mechanism includes: a first pipe having a fixing part; a second pipe having a guide part; a connection part connecting the first pipe and the second pipe; a shape memory member fixed to the fixing part and held by the guide part; and a stopper provided to the shape memory member and fixing the shape memory member. The first pipe and the second pipe are rotated about the connection part by contraction of the shape memory member. The connection part is disposed at a predetermined position relative to the first pipe and the second pipe so that the rotation range is enlarged. |
