ABSTRACT:
A conveyance device has a high-temperature pulley and a low-temperature pulley rotatably mounted on a chassis at a prescribed distance from each other and an endless belt constituted of a shape memory alloy is wound around the two pulleys. The high-temperature pulley is maintained at a temperature higher, and the low-temperature pulley at a temperature lower, than the transformation temperature of the shape memory alloy. The pulleys are rotated and the chassis powered to move by the force produced by the shape memory alloy when it restores to its memorized shape.
