摘要： A drive mechanism and a drive device each comprise a driven body (1), a displacement member (2), and an SMA actuator (3) for giving a displacement force. The driven body (1) is coupled to a fixed section through a viscoelastic member (11 (11A, 11B, 11C, 11D)). A displacement output section is engaged with the driven body, and thereby a predetermined portion of the displacement member (2) for displacing the driven body in a first-axis direction is connected to the fixed section through the viscoelastic member (11 (11E, 11F, 11G, 11H)). A shape-memory alloy (SMA) actuator is used. The position of the driven body is stably and quickly controlled. Even if a shock force is exerted or even if the drive mechanism and the drive device are left in a high-temperature environment for a long time, the SMA, the drive mechanism, and the drive device do not deteriorate, the sizes and weights thereof can be reduced, and they can be easily assembled.
