ABSTRACT:
The driving device includes a bendable shape memory alloy member, a resilient member for applying a tension to the shape memory alloy member in a longitudinal direction thereof, a bending member for bending the shape memory alloy member, and a movable body moved by a displacement of the shape memory alloy member. The bending member contacts the shape memory alloy member, so that the tension is applied to the shape memory alloy member in the longitudinal direction thereof. Compared with the driving device in which the shape memory alloy member is linearly disposed, the decrease in the amount of displacement can be suppressed, so that a space efficiency can be enhanced and the downsizing of the driving device can be accomplished.
