PROBLEM TO BE SOLVED: To follow surely to the shape of a free roller or knife edge which is a conveyer edge without relating to the longitudinal direction position of a belt by forming with a jointless circular plate shape member. SOLUTION: A curve conveyer is composed by spreading a carrying belt 2 between each other of free rollers 1, 1' arranged with 180 deg. interval. A drive mechanism 3 rotates and drives the carrying belt 2 and a hold mechanism 4 is held so as to obstruct the movement to the inside of the carrying belt 2. A cover 5 surrounds the drive mechanism 3, holding mechanism 4 and outer periphery of carrying belt 2. The belt main body 20 of the carrying belt 2 is formed by a jointless ring shape plate member and follows to the outer peripehery shape of the free roller 1 surely. Thus, it is prevented that the posture of transfered carried article is changed at the conveyer end and fallen down at the conveyer end, even if the carried article is longer than its wide.
