PROBLEM TO BE SOLVED: To provide a drive mechanism and a drive device performing a positional control of a driven body stably and at high speed, in which deterioration of shape-memory alloy (SMA) or the drive mechanism does not occur even if it is left in a high temperature environment for a long time, and the size and weight thereof are reduced, in a drive mechanism and a drive device adopting a shape-memory alloy (SMA) actuator. SOLUTION: The drive mechanism and drive device comprise: the driven body 1; a support member supporting the driven body with respect to a fixed part; a displacement member 2 having a displacement input part 2A and a displacement output part 2B, and journaling part 20 and engaging the displacement output part with the driven body to displace the driven body in a first axial direction; and the SMA actuator 3 giving a displacement force to the displacement input part. A predetermined part of the displacement member 2 is connected with the fixed part through viscoelastic members 11 (11A, 11B, 11C, 11D). COPYRIGHT: (C)2009,JPO&INPIT
