PROBLEM TO BE SOLVED: To provide an attitude control driving device capable of controlling the attitude of an attitude controlled body without a photo sensor or a motor as in the past, and controlling the attitude of the attitude controlled body without limitations on the angle to the movement of a heat source. SOLUTION: This attitude control driving device is provided with a body 10 rotatably supporting a solar battery paddle 1 through a support shaft 14, a plurality of shape memory alloys 20A to 20F disposed on the body along the moving direction of the sun and elongated and shrunk with the temperature change, and a movement converting mechanism 40 for converting the elongation and shrinkage movement of the shape memory alloy to the attitude changing movement of the solar battery paddle. The movement converting mechanism is provided with an arm 41, one end of which is connected to the support shaft 14, a wire locking ring 43 rotatably mounted at the other end of the arm 41 through a shaft 42, and connecting wires 44 connecting the wire locking ring 43 and the respective shape memory alloys 20A to 20F.
