PURPOSE: To prevent water leak by forming plural storage parts for storing a sealing compound, at a pressor plate fixed to the inner peripheral surface of a gutter bend, a joint, or the like, in the inserting direction of an eaves gutter, and storing the sealing compound in these storage parts to connect the eaves gutter.

CONSTITUTION: A pressor plate 2 is fixed to the insert side end part of a gutter bend C, formed of a metal sheet, by a rivet 23, and an insert part 21 having a gap toward the end part is formed at the pressor plate 2. The bent corner part 13 of the pressor plate 2 is provided with plural bead like storage part 22 opened at one ends in the state of bulging on the inner surface and formed to the same extent as the length of the insert part 21. A sealing compound E is applied to the pressor plate 2 and the insert part 21 of the gutter bend C. This sealing compound E is filled into the interior of the storage parts 22, and the eaves gutter is inserted and connected. Sufficient sealing effect can thereby be obtained.
