PROBLEM TO BE SOLVED: To make it possible to fix a gutter easier to the backing materials, and at the same time, to raise strength of an outer peripheral plate. SOLUTION: Such metal gutter (4) that is to guide rain water is firmly fixed and positioned in a straight line onto the backing materials (2). Onto the gutter (4), the metal holder (6) having the locking and receiving part (6d) and the plate receiving part (6e) formed at its both sides, are arranged. Onto the backing materials (2), the raising part (10a) and the upper horizontal part (10b) at the side portion, a plurality of the outer peripheral plates (10) wherein both the side raising part (10a) and the upper level horizontal part made up of a bent- formed metal plate are positioned in parallel. In the metal-made supporting body (8), the locking part (8b) which can lock the locking and receiving part (6d) and the lockable locking part (8b) of the holding part (6) and the pressing part (8a) are formed at either side. The catching part (8b) of the holding part (6) is engaged to the engaging and receiving part (6d). Thus, the upper horizontal parts (10b) (10b) of a pair of the outer peripheral plates (2) which are positioned on the side part of the backing materials (2) by the presser part (8a) and the plate receiving part (6e) of the supporting part (6) are supported in a way that they are held on the gutter (4) from the both sides.
