<P>PROBLEM TO BE SOLVED: To provide a displacement mechanism configured to obtain a large curved angle by utilizing small displacement of a shape memory alloy wire. <P>SOLUTION: This displacement mechanism includes a first pipe having a first fixing part and a connecting part, a second pipe having a second fixing part and connected to the first pipe via the connecting part, and a shape memory member fixed to the first fixing part and the second fixing part, and rotates the first pipe and the second pipe around the connecting part. When the longitudinal direction of the first pipe and the second pipe are defined as a longitudinal direction, a distance L1 along the longitudinal direction between the connecting part of the first pipe and the first fixing part of the first pipe, and a distance L2 along the longitudinal direction between the connecting part of the first pipe and the second fixing part of the second pipe, satisfy the following expression (1): L2>L1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
