Here, the auxiliary rotating body 103' can be maintained in a constant shape without being deformed, and the size of the auxiliary rotating body 103' is the depth of the receiving groove 113 of the body 101 and the installation structure 10 It is preferable that the body 101 is set to be smaller than the rotating body 103 in consideration of the degree of compression of the body 101.

In addition, in a state where the installation structure 10 on which the solar module 1 is installed is positioned and fixed on the base 20, the auxiliary rotating body 103 ′ contacts the pillar plate 13 of the installation structure 10 Can be. Here, even if vibration due to earthquake, in particular, horizontal vibration due to the earthquake S wave is applied to the base 20, the spherical auxiliary rotating body 103' is formed along the pillar plate 13 and the receiving groove 113 Since it is rotated and moved, vibration can be effectively prevented from being transmitted to the pillar 11 of the installation structure 10 as it is. In addition, since the horizontal vibration by the S wave of the earthquake is greater than the frictional force between the body 101 and the pillar plate 13, due to the frictional force, the auxiliary rotating body 103' is rotated along the pillar plate 13 Problems that cannot be moved may not occur.

In addition, even if the vertical vibration caused by the earthquake P wave is applied to the base 20, due to the elastic force of the body 101 itself, the vibration is absorbed by the body 101 and the shock caused by the vibration is alleviated, and the installation structure 10 ) May not be delivered as it is. Eventually, vertical and horizontal vibrations caused by earthquakes are absorbed by the body 101 and the auxiliary rotating body 103', and the shocks caused by the vibrations are alleviated, so that the vibrations and shocks caused by the earthquake are not affected by the installation structure 10. May not be delivered.

Meanwhile, the auxiliary rotating body 103 ′ may be positioned to correspond to the central groove 115 in a state received in the receiving groove 113 of the body 101. Here, the auxiliary rotating body 103 ′ may be positioned in a stopped state in the center of the receiving groove 113. When horizontal vibration is applied to the base 20, since the auxiliary rotating body 103' is moved while being rotated along the pillar plate 13 of the installation structure 10, the auxiliary rotating body 103' is the receiving groove 113 ) Can also be moved while rotating. Here, the auxiliary rotating body 103 ′ is located at the center of the receiving groove 113 by the central groove 115, so that it can be rotated and moved at the maximum distance in all directions in the receiving groove 113.

In some cases, even in a state in which the auxiliary body 102 is inserted into the insertion hole 111 of the body 101 and accommodates the rotating body 103 through the auxiliary receiving groove 121, each of the receiving grooves 113 In the auxiliary rotating body 103 ′ smaller than the rotating body 103 may be accommodated.
