PROBLEM TO BE SOLVED: To provide a cross conveyor chain capable of shortening a length of a transfer protruding piece, capable of avoiding bending and damage, capable of stably and smoothly feeding an article to be fed, preventing partial concentration of load, avoiding bending along the vertical direction, superior in strength, rigidity and durability, easily constituted in light weight, small size, and compact, simple in a structure, suitable for mass production, easily assembled, easily handled, capable of easily achieving reduction of a cost, and economical. SOLUTION: A first conveyor chain S1 is supported by an end bar 10 or a small diameter sprocket. A second conveyor chain S2 is constituted at least by two kinds of chain units A having different lengths and a connection pin B. In the chain unit A, a front end protruding part 1 and a front end recessed part 3 are alternately arranged at a front part, and a rear end protruding part 2 and a rear end recessed part 4 are alternately arranged at a rear part. The transfer protruding piece 7 is continuously provided on one side part integrally; an inclined lower surface 8 is formed on a tip lower surface thereof, and an inclined top surface 9 is formed on a tip upper surface thereof, respectively.
