An orientation varying mechanism 10 is provided with: joints 12; holding parts 14 that hold the orientation of the joints 12; heating parts 16 that heat the holding parts 14; wires 20a and 20b that have the joints 12 interposed therebetween and that extend from one side toward the other side; an actuator 22 that pulls the wires toward the one side; and a pulled part, provided on the other side, that is pulled together with the joints 12 when the wires 20a and 20b are pulled. The wires extend to the pulled part. The holding parts 14 become deformable when an external force is applied by means of heat from the heating parts 16 and the orientation of the joints varies according to the pulling of the wires 20a and 20b by the operation of the actuator.
