Abstract

PURPOSE:To prevent a tension wire from being applied with a torsional force by a method wherein a shape memory alloy wire, arranged so as to be located at the focus of light collecting section, is utilized as a swing motion transmitting mechanism to permit to track the sun without employing electric power and a connecting terminal is attached to at least one of the fixing end of the shape memory alloy wire and the connecting terminal of the tension wire. CONSTITUTION:When a sensor collector 10x, opposing to solar light, collects the light to the focus thereof, the shape memory alloy wire 11x is heated and contracted into the shape of coil thereby pulling a tension wire 12x, connected to one end of the wire 11x, into X-direction. As a result, a rotating frame 6, connected through a pair of worm gears 16, is rotated into Y-direction and changes the position of a main collector 8 so as to oppose to the sun. The shape memory alloy wire 11 rotates into A-direction when it is extended while rotates into B-direction when it is contracted. Therefore, the connecting terminal 17 is attached to at least one of the fixing end of the wire 11 and the connecting terminal of the tension wire 12, whereby, the rotating motion is absorbed and the same motion is not transferred to the tension wire.
