PROBLEM TO BE SOLVED: To perform opening-closing operation of an eyeball by a low weight, low cost, reliable and simple mechanism element. SOLUTION: Opening-closing and inclining operation is realized by changing a combination of the expansion-contraction of a plurality of wire actuators 102 composed of a shape memory alloy and substantially radially installed on the peripheral edge of an upper eyelid member 101. Optional two wires can be driven without connecting power supply wiring on the moving side by electrically connecting the moving side of the respective wire actuators 102. A wire part protruding from an eyelid opening-closing driving mechanism, is covered with a heat resistant insulating tube, and the wires are curvedly mounted along a cranial frame.
