The present invention relates to a stain-preventing rainwater drain apparatus for a rooftop installed in a corner of a rooftop of a building to prevent rainwater from flowing down on an outer wall of the building. The stain-preventing rainwater drain apparatus for a rooftop comprises: a body (110) having a bar hole formed on both sides thereof; a rainwater receiving pan (120) integrated into a side of the body along a longitudinal direction, and extended in a width direction of the body to induce rainwater falling thereon to flow in the width direction; a wall support unit (130) integrated in to a lower portion of the body in the longitudinal direction, and extended downwards to form a right angle with the rainwater receiving pan to tightly be attached to a wall surface to perform a supporting function when fixated on a corner of a building; a connection bar (140) whose one portion is inserted into the bar hole whose remaining portion protrudes from the body; a tight contact plate (150) having a through hole formed therein to come in contact with one end of the body while inserted in the connection bar; and an adhesive film (160) formed on the tight contact plate and affixed to an upper surface of a side end of the body and the rainwater receiving pan to cover a gap of a connection portion. |
