To easily perform machine work like cutting work and decrease cost of manufacturing.SOLUTION: A crushing roller 13 comprises: a journal housing which is supported rotatably around a center axis C2 in a housing; and a toric roller part 49 which is engaged with an outer periphery part of the journal housing from outside and crushes a solid fuel between a crushing table and the crushing roller. The roller part 49 includes: a workpiece part 53 which is engaged with the outer periphery part of the journal housing from outside; and a base part 51 which is arranged at an outer periphery part of the workpiece part 53. The workpiece 53 made of a material with excellent workability in comparison with the base part 51, includes: an inner periphery part 54 which covers the inner peripheral surface of the base part 51 and contacts with the outer periphery part of the journal housing; and an edge face part 55 of the roller part 49 in the center axis C2 direction.SELECTED DRAWING: Figure 4 【課題】容易に切削加工等の機械加工を施すことができ、製造コストを低減することを目的とする。【解決手段】粉砕ローラ１３は、ハウジングに対して、中心軸線Ｃ２を中心として回転可能に支持されるジャーナルハウジングと、ジャーナルハウジングの外周部に外側から嵌合し、粉砕テーブルとの間で固体燃料を粉砕する円環状のローラ部４９と、を備えている。ローラ部４９は、ジャーナルハウジングの外周部に外側から嵌合する被加工部５３と、被加工部５３の外周部に設けられる基部５１と、を有している。被加工部５３は、基部５１の内周面を覆いジャーナルハウジングの外周部に接触する内周部５４と、ローラ部４９の中心軸線Ｃ２方向の端面を為す端面部５５と、を有し、基部５１よりも加工性の良い材料で形成されている。【選択図】図４
