Here, the vertical rail 3 is fastened and fixed to the horizontal rack 7 by using anchor bolts, flat plate seats 25, washers 26, and top nuts 27 (see FIG. 7). For this reason, the angle of the horizontal rack 7 with respect to the vertical rail 3 can be arbitrarily adjusted. Therefore, the extending direction of the horizontal rack 7 does not need to be orthogonal to the vertical beam 3 and does not need to be parallel to the horizontal beam 6. Therefore, the horizontal rack 7 can be installed in an arbitrary direction, and attachment work is facilitated.

(Fourth embodiment)
In the fourth embodiment, as shown in FIG. 13, a roof mount device composed of a vertical beam 3 and a horizontal beam 6 is fixed to a tiled roof using a base plate 16. The base plate 16 is a plate material having a length substantially equal to the interval between the rafters 95 of the tile roof, and is placed on the field board 94 between the tile 96 and the rafter 95, and both ends thereof are adjacent to each other. The rafters 95 are respectively fixed by nails or wood screws 18. The tile 96 is a roof material, and may be any style of tile, such as a Japanese tile or a Western tile.

  The base plate 16 has a locking slit 19 at the center. The locking slit 19 extends in the roof girder direction Y in the same manner as the extending direction of the base plate 16. As shown in FIG. 14, a fixing bolt 21 at the lower end of the column bolt 2 is fixed to the locking slit 19 by tightening with the presser nut 22. In this case, the position of the support bolt 2 on the locking slit 19 is adjusted so that the upper side protrudes from the through hole P previously drilled in the top of the roof tile 96. The through hole P is sealed with a caulking material 20 for preventing rainwater from entering.

  Similar to the first embodiment, the upper thread portion 2a of the support bolt 2 penetrates the vertical beam 3, and is formed by two upper and lower level nuts 23 and a top nut 27 that are screwed into the vertical beam 3 to the screw portion 2a. A flat plate seat 24 is interposed between the vertical beam 3 and the level nut 23, and a flat plate seat 25 and a washer 26 are interposed between the vertical beam 3 and the top nut 27 ( (See FIG. 2). A vibration absorbing material such as rubber may be further interposed between the vertical beam 3 and the flat seat 24.

  The level nut 23 and the top nut 27 constitute the height adjusting means of the vertical beam 3 as in the first embodiment. Similarly to the first embodiment, a horizontal beam 6 is fixed to the vertical beam 3 in a cross beam shape using a catcher 5, and a photovoltaic power generation panel is fixed to the horizontal beam 6.

  In the fourth embodiment, in order to project the support bolt 2 from the roof tile 96, the roof tile 96 is drilled. However, the position of the support bolt 2 is aligned with the top of the roof tile 96, and the locking slit 19. Since it can be adjusted in the lateral direction, the through hole P can be formed at the top of the roof tile 96.

  Furthermore, since the vertical beam 3 is fixed by providing two level nuts 23 and a top nut 27 on the upper part of the column bolt 2, the vertical beam 3 and the horizontal beam 3 are applied so that the load on each column bolt 2 is evenly applied. The height of the crosspiece 6 can be adjusted, and the rigidity of the vertical crosspiece 3 and the horizontal crosspiece 6 serving as a basic foundation can be secured. Thereby, the planar uniformity of a roof tile can be absorbed and the planar state of the surface of the photovoltaic power generation panel 4 can be made favorable.
