PROBLEM TO BE SOLVED: To provide a bucket for a groove, which can easily discharge soil which has been deeply dug out with a predetermined width, from the interior of the bucket. SOLUTION: A bucket for a groove is made up of a stay portion 3 to which an operating member of a construction machine main body is linked, a bucket bottom plate 2 being coupled to the stay portion 3 in one body and having a bottom surface 2 internally curved like an arc, and right and left excavating blades 4 each coupled to a location between the front end of the bucket bottom plate 2 and the front end of the stay portion 3. A side surface between the bucket bottom plate 2 and each excavating blade 4 is opened. A pair of the bucket members each having the above construction are arranged such that the excavating blades 4 face each other, to thereby construct a pair of clamshell buckets.
