According to this configuration, the vertical rail and the mounting bracket are screwed through the small holes of the mounting bracket, so that the longitudinal force of the groove is increased by the external force such as wind and rain, snow, or the weight of the module base. Even if the force to move the vertical rail acts on the vertical rail, the vertical rail does not move. In addition, since the small hole of the mounting bracket is formed in the shape of a long hole with a long diameter in the same direction as the through hole, even when adjusting the vertical beam in the vertical direction, a part of the vertical beam is inserted into the small hole. If it partially faces, the vertical rail and the mounting bracket can be screwed at that part. The screw is preferably a text screw or a tapping screw.

Further, in this case, a washer is interposed between the bolt and the mounting bracket, and a plurality of small grooves extending in the longitudinal direction of the vertical rail are formed on the surface of the washer on the mounting bracket side. Is preferred.

According to this configuration, since the small groove extending in the longitudinal direction of the vertical bar is formed on the surface of the washer on the mounting bracket side, when the vertical bar and the mounting bracket are fastened using this washer, The small groove of the washer cuts into the surface of the mounting bracket, and the coefficient of friction between the mounting bracket and the washer in the direction perpendicular to the longitudinal direction of the vertical rail, that is, in the vertical direction, increases. For this reason, even if the vertical rail receives an external force from above due to snow accumulation or the like and the bolt for fastening the vertical rail and the mounting bracket attempts to move downward along the through hole, the movement is prevented by the washer, and The crosspiece can be firmly fixed against a vertical force.

Further, in this case, it is preferable that a plurality of protrusions that engage with the small grooves extend on the surface of the mounting bracket on the washer side.

[0014] According to this configuration, since the convex portion that engages with the small groove of the washer is formed on the surface of the mounting bracket, the coefficient of friction between the mounting bracket and the washer in the vertical direction is further increased. Therefore, even if the vertical beam receives an external force from above, the vertical beam does not move downward, and the vertical beam can be more firmly fixed to the force from above.
