PURPOSE:To obtain a temperature-sensitive driving mechanism having a compact size, acting without using a power source, having excellent simplicity and handleability and useful e.g. for greenhouse for plant culture by integrating a transmission member made of a specific shape-memory alloy into a pantograph. CONSTITUTION:This temperature-sensitive driving mechanism is produced by connecting a stationary end 7a of a pantograph 7 composed of plural extension elements 10 having quadric link structure to the upper end of a restriction member 8 having a weight table 9 at the lower end and erected on the weight table 9, connecting the mobile end 7b of the pantograph 7 to a follower member 6 and forming the part near the stationary end 7a of the pantograph 7 with a transmission member 24 made of a shape-memory alloy. The transmission member 24 is deformed to the original form at a specific transformation temperature to contract the pantograph 7 and pull up the follower member 6. |
