PURPOSE:To make a rotary shaft rotatable with a temperature differential utilized, by installing a deformable temperature detecting part, as a simple substance, at the base end side of a connecting rod installing a weight in its tip end, while attaching the plural numbers of this simple substance to a periphery of the rotary shaft set up in and around a boundary surface between the atmosphere and a liquid. CONSTITUTION:A rotary shaft 3 is horizontally installed in and around a boundary surface H between the atmosphere having a temperature differential and a liquid through bearings, and plural numbers of simple substance 1-1-1-8 (hereinafter, appended figures omitted) are radially set up in this rotary shaft 3 at the specified intervals. Each simple substance 1 is made up of installing a retractable temperature detecting part (or an expandable coil-form temperature detecting part) 7 composed of a form memory alloy and a bimetal at the base end side of a connecting rod 6 installing a weight in its tip end. This temperature detecting part 7 is bent and expanded longer as shown in illustration when ambience temperature varies, whereby each simple substance 1 is installed so as to make it deformable in a state of being bent by about 90 deg. from the initial straight line state. And, utilizing the deflection of a center-of-gravity position of the whole device caused by deformation of the simple substance 1, the rotary shaft 1 is made so as to be rotated. |
