In the present invention, in constructing the vinyl house heat insulating cover switch,A drive motor 4 is coupled to the outside of the main body case 6 and a connecting rod 8 is coupled to the lower side of the main body case 6. A drive motor A plurality of reduction gears for receiving and decelerating the rotational force of the drive shaft 4 are interlocked one after another,The main body case 6 is partitioned into a first case 6a and a second case 6 and the first and second gears 12 and 22 are housed in the partitioned first case 6a In the second case 6b, the third to fifth gears 32 to 52 are built in,The drive shaft of the drive motor 4 coupled to the first case 6a extends into the first case 6a and the drive gear 4a is coupled to the end of the drive shaft,The first reduction gear 12 coupled to the first axis 10 is coupled to the driving gear 4a and the first reduction gear 12 coupled to the first axis 10 is coupled to the first interlocking gear 14 14 are meshed with a second reduction gear 22 coupled to the second axle 20,The second axial rod 20 extends into the second case 6b and is coupled to the second interlock gear 24 at its end and is coupled to the third axial rod 30 at the second interlock gear 24. [ 3 reduction gear 32 are engaged with each other,A third interlocking gear 34 is coupled to the third axis 30 and a fourth reduction gear 42 coupled to the fourth axis 40 is meshed with the third interlocking gear 34,A fourth interlocking gear 44 is coupled to the fourth axis 40 and a fifth reduction gear 52 coupled to the fifth axis 50 is engaged with the fourth interlocking gear 44,The driving gear 4a coupled to the driving shaft of the driving motor 4 and the five reduction gears 10 to 50 and the four interlocking gears 14 to 44 are formed of helical gears, In addition,The fifth axial bar 50 is configured to protrude to the outside of the second case 6b of the main body case 6 so that the wind bar 200 wound around the heat shield lid 300 at the end of
