PURPOSE: To eliminate the shortage of strength in uplift prevention sections by projecting both side bending sections of a main body metal fixture upward of a gutter plate section in an unchanged state to form the uplift prevention sections.

CONSTITUTION: Both side bending sections 19 of a main body metal fixture 17 forming a gutter hanger metal fixture 12 are bent downward to from a U-shaped section. A plate section 21 of a gutter 11 is formed of an inclined surface 22 bent downward from specific positions of the front end sections of the bending sections 19, a horizontal 23 and an interlocking claw 24 having the upward front end and, at the same time, the front end sections of positions from which inclination to the inclined surface 22 of the bending sections 19 starts are used as uplift prevention sections 25 of the gutter 11. After that, the main body metal fixture 17 is borne on a bearing metal fixture 18 through a slide adjusting section 31. According to the constitution, in the case upward force is acted by wind blowing against the gutter 11, a projection 16 of an outside gutter lug 13 is interlocked with the uplift prevention sections 25 to prevent uplift.
