Abstract

PURPOSE: To improve functions by forming an eaves end water drip board of a first piece positioned on the upper face of a protruding part of eaves end and a second piece suspended from the end of the first piece to cover the eaves end, and a third piece touching an end board at its end while projecting from the rear face. CONSTITUTION: In an eaves end water drip board 19 a first piece 19a is placed on the upper face of an eaves end projection part 16a and fixed by means of a nail 20. A second piece 19b is suspended downwards to the upper part of eaves gutter 14 to guide rainwater flowing along the surface of a roof into the eaves gutter 14. A third piece 19c closes the lower face of the projection part 16a to prevent it from being decayed by rain, snow or the like and also prevent it from being burnt from fire of neighboring house. Even if some difference between the lengths of third pieces 19c is generated it can be coped with through change in the inclination angle. Furthermore, even if wind, earth or the like is acted on the third piece 19c, the watertight characteristics is not damaged since an end of the piece 19c is pushed against an end board 12. It is thus possible to dispense with a tilting board to thereby reduce the number of part and to assure easy construction with improved watertightness and fireproofness.
