2. Description of the Related Art In recent years, with increasing interest in global environmental issues, a photovoltaic power generation system that converts solar energy into electric power by a solar cell has attracted attention as one of new energy technologies using natural energy. The use of solar cell modules on roofs of houses and the like is often performed as one of its practical forms.

[0003] For example, FIG. 10 is a schematic view illustrating this practical form. As illustrated in FIG. 10, the solar cell module (3) includes a base plate (11) and a waterproof base material (1).
It is attached between the respective mounting rails (2) arranged on the roof base material (10) such as 2). The solar cell module (3) is usually a solar cell mounted on a frame member, and the frame member is fixed to the mounting rail (2). In this case,
The solar cell module (3) also serves as a roof finishing material,
The roof (1) is finished with the solar cell module (3) and the tile material (13) placed beside the solar cell module (3). The roof (1) in which the solar cell module (3) also serving as a roof finishing material is mounted on the roof base material (10) via the mounting rail (2) is referred to as a solar cell roof (1). And In the solar cell roof (1) of FIG. 10, a dummy module (4) is provided on the ridge side of the solar cell module (3), and a ventilation ridge member is used instead of the normal ridge member (14). (15) is provided, and ventilation of the solar cell module (3) is performed via the dummy module (4) and the ventilation building member (15).

FIG. 11 is a cross-sectional view showing a more specific example of a solar cell module (3) and a mounting rail (2) in a solar cell roof (1), which is provided by the inventor of the present invention. It has already been developed (see JP-A-11-159071). In the example of FIG. 11, the mounting rail (2) includes a fixed cover body (21),
It has a frame support part (22) and a flow trough piece part (23), and is fixed by a fixing screw (24) on a waterproof base material (12) laid on a base plate (11). On the other hand, the frame member (32) of the solar cell module (3) includes a fitting portion (321), a screw portion (322), and a draining portion (323), and the fitting portion of the frame member (32). The solar cell module (3) is formed by fitting the peripheral edges (that is, the left and right vertical edges and the ridge / eave side horizontal edges) of the solar cell (31) into (321). Then, the frame member (32) of the solar cell module (3) is placed on the frame supporting portion (22) of the mounting rail (2), and the fixing cover body (26) is tightened by the fixing bolt and nut fitting (26). 21) Frame member holding portion (211) and frame support portion (22)

The water flows toward the eaves without leaking in 0). Therefore, an effective waterproof structure is realized between the solar cell modules (3) at the left and right ends of the solar cell roof (1) and the mounting rail (2) and the tile material (13) adjacent thereto.

[0007]

However, in the conventional waterproof structure as illustrated in FIG. 12, there are practically the following points to be improved in relation to the type of the tile material (13). I was First, the waterproof structure illustrated in FIG. 12 will be further described.
The side cover piece (251) is set between the tile holding part (253) and the drain plate (6). In this case, rainwater and the like are blocked by the side cover piece (251). And even if it intrudes,
3) can only enter through the gap between the tile material (13),
Side cover piece (251) and tile material holding part (253)
The primary waterproofing is realized by. Furthermore, even if rainwater or the like invades from the gap, the drainage plate (6) allows the water to flow toward the eaves, and a small amount of rainwater transmitted between the tile material (13) and the drainage plate (6) is also drained. The secondary waterproofing is realized by the draining plate (6) and the folded portion (62) without being blocked by the folded portion (62) of the plate (6) and leaking to the roof base material (10).

However, in such primary waterproofing and secondary waterproofing by the conventional waterproofing structure, the tile material (13) has a structure in which the tile material holding portion (253) and the drain plate (6) are formed as shown in FIG. It can only be realized in the case of thin roof tiles whose ends can fit in between. That is, a thick material such as a clay tile or a concrete tile having a complicated surface shape and thickness such that the end cannot be pressed or hidden by the tile material holding portion (253) or the side cover piece (251). When a tile is used as the tile material (13), the primary waterproofing is not naturally performed by the side cover piece (251) and the tile material holding part (253) as described above, and Part cover part (251) and tile material holding part (253)
It falls directly on the draining board (6) without being interrupted by the water. Of course, the drain board (6) must flow a large amount of rainwater or the like toward the eaves, but as described above, a small amount of water transmitted between the tile material (13) and the drain board (6). In the folded portion (62) made in consideration of the blocking of rainwater or the like, it is very difficult to effectively dampen further rainwater or the like.

As described above, in the conventional waterproof structure, the tile material (1
When thick tiles are provided as 3), it is difficult to effectively prevent water leakage into the roof base material (10) and the like. The invention of this application has been made in view of the circumstances described above, and solves the problems of the prior art. Therefore, the solar cell modules (3) at the right and left ends of the solar cell roof (1), specifically, When thick tiles are arranged beside the mounting rail (2) to which the solar cell modules (3) at the left and right ends are mounted, the roof base material (10)
It is an object of the present invention to provide a new waterproof structure for a solar cell roof that can effectively prevent water leakage to a solar cell or the like.

[0010]
