PURPOSE:To quicken the repeating motion by employing a plurality of shape memory elements having reverse shape memory effects under a specific temperature and another specific temperature risen through heating. CONSTITUTION:When applying onto a gripping device, a pair of shape memory alloy boards 1A, 1B inflatable outward under normal temperature and another pair of shape memory alloy boards 1C, 1D inflatable inward are employed in order to secure the reinforcing boards 4, 4 fixed with one ends of the alloy boards 1C, 1D to the frame 5. Then one ends of another pair of alloy boards 1A, 1B are secured through reinforcing boards 41, 41 also serving as coupling tools to the other ends of the alloy boards 1C, 1D while reinforcing boards 6, 6 having attachments 61, 62 functionable as gripping means are secured to the other ends of them. Consequently, quick repeating motion can be achieved in accordance with power conduction control. |
