To provide a holding structure for an eaves gutter that can hold an eaves gutter changed in the shape and height of an outer region positioned under a bend portion, with a common eaves gutter hanger, and prevents the loosening of the eaves gutter and disengagement of the outer region of the eaves gutter even when an external force acts on the eaves gutter in a vertical direction or a width direction.

The substantially vertical middle of the outer region 4 of the eaves gutter 1 has the bend portion 9 bent substantially in a U-shaped section toward a building 3 as delimiting a drip groove 8 on the face opposite to the building 3. An upper horizontal region 10 of the bend portion 9 is slanted for higher positioning with closeness to the building 3 to form a slant region 11. A raised region 14 has an outer ear portion lock portion 16 at an upper end and has a lower lock portion 17 at a lower end. An outer ear portion 5 of the eaves gutter 1 is locked on the outer ear portion lock portion 16 of the eaves gutter hanger 2, and the slant region 11 of the eaves gutter 1 is locked on the lower lock portion 17 of the eaves gutter hanger 2.
