The sector gear S is fixed to the link rod 10 connected to the support arm 7, and the rotary screw rod 1 driven by a motor is mounted on the sector gear S.
The concave mirror 2 supported on the tip of the support arm 7 is rotated in the declination direction by engaging 1 (fixed to the fixed shaft 6 with support means not shown). Two motors (not shown) for detecting the sun's movement in the declination direction and the right ascension direction are interlocked with each motor for rotating the rotary screw rods 9 and 11, and the mirror axis 2a of the concave mirror 2 is It always faces the sun. In the present invention, the automatic tracking of the sun is not limited to the one using the light amount sensor.

ある。Further, in the solar heat utilization apparatus 1 of the present embodiment, the load on the motor of the rotating screw rods 9 and 11 is small. This is because the counterweight 12 is provided at a position extending from the link rod 10 in the direction opposite to the concave mirror 2 so that the concave mirror 2 balances in any direction.
