ABSTRACT:
An assembling apparatus (manufacturing apparatus) can assemble an actuator (product) in which a shape memory alloy (SMA) is stretched. In the assembly, the SMA is locked by a first holder, a guide is moved along predetermined movement directions while sending the SMA and, after that, the SMA is locked by a second holder. A switch is turned on to pass current from a current source to the SMA via an electrode. The SMA is fixed to two electrodes by caulking members and, after that, an unnecessary portion of the SMA is cut. In such a manner, the actuator is manufactured. Since the SMA is tensioned while current is passed to the SMA as described above, the stretch can be stably performed while suppressing elongation of the SMA. As a result, a product can be manufactured with high quality.
