Related to the structure.

  Conventionally, at the installation site of a fence to a building, the lower end is cut at a predetermined position with the upper end of the fence connected to the eaves in advance and inserted into the drain pipe cover. In this case, since the lower end of the ridge is cut without being inserted into the drain pipe cover, in rare cases, the lower end of the ridge when inserted into the drain pipe cover is positioned appropriately with respect to the drain pipe cover. The state that it is not disconnected by occurs. For this reason, there has been a problem that the quality deteriorates due to rainwater leaking from the drainage pipe cover due to the occurrence of gaps and damage to the drainage pipe cover / basket due to thermal expansion and contraction due to seasonal temperature changes.

  A method for solving this problem is disclosed in Patent Document 1. As shown in FIG. 6, the drain pipe cover G is a cylinder body 1 having a gutter insertion port 5 at the upper end and a drain pipe insertion port 6 at the lower end. An opening 8 for insertion is formed by cutting out from the upper end to a substantially intermediate height.
