To facilitate installation work to the eaves edge, by preventing a stain of the eaves edge by smoothly draining rainwater, by effectively preventing infiltration of the rainwater into a roof backing, while blocking up clearance between a roof tile of the eaves edge and an eaves wide board.

In this eaves edge rafter clearance 1, a base board part 12 is obliquely downward slantingly extended from the downstream side edge of a belt-like fixing plate part 11, and a thin plate-like filler strip part 13 for clearance between rafters and sheathing roof boards adjusted to a front shape of the clearance of the eaves edge, is substantially vertically erected to the base board part 12 on the edge of the downstream side of this base board plate 12. A drain hole 14 is formed in a corner part between the base board part 12 and the clearance boards 13. The fixing plate part 11 is fixed to an upper part of the eaves wide board 4, and the base board part 12 and the filler strip part 13 are fixed by overhanging in the eaves edge direction more than the tip of the eaves wide board 4.
