  That is, as shown in FIG. 3 which is an enlarged sectional view taken along the line A-A in FIG. 2 and FIG. 4 which is a sectional view taken along the line B-B in FIG. As shown in FIG. 3, the upper vertical rail 1 is formed to be vertically elongated with the left and right side pieces 4c and 4c longer than the upper piece 4b and the bottom piece 4d and with a width and a width of 1: 3 to 4, respectively. And the hollow cross section of the vertical cross section main body 4 is wider than the vertical cross section main body 4 in the hollow longitudinal cross cross section main body 4 in which the hollow section is formed in the longitudinal reinforcement hollow section 4a; 4 is composed of a metal fitting engaging slide base 5 integrally formed in the longitudinal direction of the panel 4, and the metal fitting engaging slide base 5 is mounted on the panel for engaging and sliding the sliding surface 5a and the engagement groove 5b.

It is held by the spring engagement holder 7.

  The panel pressing spring 10 is curved in a U-shape flat downward in the longitudinal direction of the spring engagement holder 7 by an aluminum type member as shown in FIGS. 4 to 7, exactly as shown in FIG. 7, The side to which the photovoltaic panel P is inserted is formed as the gently inclined surface 10b on the opposite side as the gently inclined surface 10a, and the thickness is 1.2 mm, and the width in the longitudinal direction is 22.5 mm in plan view The width corresponding to this is 32 mm. Then, the panel pressing spring 10 is configured to fix the photovoltaic panel P by its elastic force by utilizing the elastic deformation of the aluminum shape material. In order to manufacture the panel pressing spring 10, it is suitable for mass production by, for example, forming a large number of elongated aluminum members formed by extrusion on a 32 mm long side cut piece in the above example, for example. Since the pieces have exactly the same cross-sectional shape, it is possible to fix the plurality of photovoltaic panels P with uniform pressing force without variation by manufacturing the panel pressing spring 10 with such an aluminum type material.
