The present invention has the following effects.

According to a first aspect of the present invention, the lower base portion of the vertical front plate portion is bent at a right angle to form a bottom portion, and the bottom portion is extended to form a folded portion, and the folded portion is formed. The upper part of the vertical part is extended to form a leg part having a small hole in the rear part, and the upper end part of the vertical front plate part is bent at an acute angle to form an inclined pop-out prevention part. The lower end of the pop-out prevention portion is bent outward to form a horizontal portion, and the bottom portion and the horizontal portion are fixed to each other, and the upper end portion of the vertical front plate portion is used as a base point. The L-shaped angle is bent and supported by pressing the L-shaped angle inserted into the L-shaped angle fitting insertion portion formed by the front plate portion, the bottom surface portion and the pop-out prevention portion from the window hole formed in the protrusion preventing portion. Since it is an L-shaped angle support fitting for a roof in which a pressing support part is formed, the L inserted by the pressing support part is inserted.
Since the vertical plate portion of the mold angle is pressed firmly and firmly, and rainwater or the like adheres between the pressing support portion and the vertical plate portion of the L-shaped angle, it immediately flows out. There is no risk of corrosion between the L-shaped angle and the pressing support.

Further, according to the present invention, since the shape of the window hole is larger than the shape of the pressing support portion, the pressing work can be made extremely smooth.

According to a second aspect of the present invention, the pressing support portion is provided in the direction of the L-shaped angle fitting insertion portion with the bent base portion of the inclined protrusion prevention portion and the horizontal portion as a base point. Since it is an L-shaped angle support fitting for a roof characterized by being formed, the pressing support portion firmly presses and supports the horizontal plate portion of the inserted L-shaped angle. Therefore, the inserted L-shaped angle was prevented from rattling.

According to a third aspect of the present invention, the pressing support portion is formed with the upper end portion of the vertical front plate and the bent base portions of the pop-out prevention portion and the horizontal portion as base points, respectively. Since it is an L-shaped angle support fitting for use, it presses firmly and reliably from both sides of the vertical plate portion and the horizontal plate portion of the L-shaped angle in which the pressing support portion is inserted. Therefore, the L-shaped angle has an advantage that it does not rattle.

The invention according to claim 4 is an L-shaped angle support fitting for a roof, in which a snow stopper plate of a predetermined shape is attached to the front surface of the vertical front plate portion. By the above-mentioned pressing support portion, it can be securely and firmly fixed to prevent rattling.

Further, even with the above-mentioned snow stopper plate, the snow stopper function can be exhibited before the L-shaped angle is fitted.
