PROBLEM TO BE SOLVED: To provide a gutter cover bringing about the solution of such a problem that a gap is formed between gutter covers installed consecutively for use in a U-shaped gutter block made of concrete to generate a play in the gutter cover in an end part or make the wheel of a baby carriage caught in the gap at times due to the winter shrinkage of the plural gutter covers and the deviation in one direction, caused by the passage of vehicles. SOLUTION: The gutter cover is composed of isosceles triangle-shaped main gutter covers (1), (1), etc., used for the U-shaped gutter block and right angled triangle-shaped sub-gutter covers (2) and (3) formed by separating the cover (1) into two right and left parts. The gutter cover is constituted as follows: a locking groove (8) is formed on a perpendicular (15) dropped from an intersection point (14) to a base (13) at the center of the bottom surface of the intersection point (14) of two equal sides of the gutter cover (1) disposed at the center of the gutter block; the locking groove (8) is formed by installing holding pieces (10) and (10) in a hanging condition on both sides of the perpendicular (15) in the rear surface of a cover plate on the side of the base (13); and the locking groove (8) is locked to a locking piece (23) installed in an upraised manner at the center of a receiving frame (22) attached in such a manner as to cover the gutter cover suspension part of the gutter block.
