PROBLEM TO BE SOLVED: To provide a vertical gutter support tool which has a high locking strength, in which the engage locking of a locking projection of a lid with a locking projection of a body is never released through impact or thermal expansion/contraction caused by a temperature difference. SOLUTION: The locking projection 11 of the body 10 is formed into a curved shape by bending the end of a curved strip body to the outside, and a locking recess 12 is formed in the vicinity of the bent base 11a of the locking projection 11 to prevent the locking piece 21 of the lid 20 from sliding down.
