PROBLEM TO BE SOLVED: To enhance cooling efficiency inexpensively by constituting a stoker of a substantially rectangular body section establishing the longitudinal direction, providing an integrally cast snaking pipe and disposing a part of a cooling pipe to run in the longitudinal direction. SOLUTION: The stoker block 1 is substantially formed into a rectangle having a predetermined longitudinal direction L being defined by an upper wall 23, side walls 29a, 29b, front wall 24 and rear wall 21. Two blocks 22 are mounted on the rear wall 21. A cooling pipe 16 and coupling pieces 30, 43 are arranged in the block 1 to run symmetrically to a plane S of symmetry. A part 16a of the pipe 16 runs freely in a first segment and then it is introduced into a casting toward the front wall 24. The part 16a runs in the longitudinal direction L and continues from a bend 16b to a part 16e. According to the structure, the stoker block can be manufactured at low cost and cooled very efficiently.
