ABSTRACT:
An operating device has a pair of linear members (43, 44) made of a shape memory alloy and contracting axially due to heat generated by electrification and generating tension in the contracting direction, a drive lever (19) supported to pivot about a pivot shaft (19a), a pair of drive rods (33, 34) respectively connected to both sides of the drive lever (19) with the pivot shaft (19a) being disposed between the sides of the drive lever (19), and a power supply circuit for selectively electrifying the linear members (43, 44). One end of each of the linear members (43, 44) is fixed to a stationary member, and the other end is connected to each of the drive rods (33, 34).
