In this case, the spacer is provided. The spacer and the fixing plate are provided with fitting portions that fit each other.
[0004]
[Problems to be solved by the invention]
By the way, the gutter mounting fixture having the above structure, when fixing to a gable plate or the like, passes a screw or the like through a fixing hole and tightens the screw and fixes it, but a rigid spacer such as stainless steel or aluminum is interposed. In such a state, a high stress may be generated around the fixing hole, and a crack may be generated. As a result, the plasticizer that oozes out of the vinyl chloride coated steel plate of the gable plate due to aging changes enters the fixing hole from the screw mounting part, and touches the cracked part, causing deterioration around the fixing hole. There is a problem that is easily promoted.
[0005]
In addition, the former gutter fixture needs to adhere the additive blocking film, and the sticking process is troublesome and cost increases, and the latter gutter fixture is easily disengaged even when the spacer is engaged, so that it can be easily removed during fixing work. Since the spacer comes off, it is necessary to increase the fitting accuracy of the parts, and there has been a problem that the work of mounting the parts becomes complicated.
