Since the cover side surface material 23 having a predetermined distance k remains between the 24 and the lower end 21a of the cover top surface material 21, it is possible to prevent the cover top surface material 21 from being deformed by the reaction force from the cable 31, and it is watertight. Can be enhanced.
Further, since the rainwater flowing down from the cover top surface material 21 flows in a direction away from the covering material 24 along the inclination of the lateral slit 25c, the intrusion of rainwater from the cable 31 can be reduced. Further, according to the present embodiment, when both ends of the covering material 24 are bent by the lateral slit 25c, the sides (formed by the lateral slit 25c) of both ends of the covering material 24 on the cover side surface member 23 side. Since the cover surface of the cover material 24 is inclined downward because the side surface of the cover is parallel to the surface of the cover side material 23, rainwater flowing from the cover top surface material 21 to the cover material 24 can be smoothly dropped. can.
The distance between the pair of vertical slits 25b is narrower than the distance between the pair of support plates 15 (see FIG. 5).
In this way, the gap created by forming the covering material 24 can be narrowed and the water blocking property can be improved.

The cable lead-in unit such as a solar cell according to the present invention may be a metal roof, a slate roof, a double-flow roof, a single-flow roof, or a roof having a different slope. Can be constructed.
