    • PURPOSE: To aim at the mass production and improvement of hardness in a rail wheel having the conjugate fiber structure by forming an inner core of plural hollow cassettes formed by integrating the foaming filling material with the conjugate fiber and having a width enlarged outside in the radial direction adjacent to each other so as to be directed to the periphery. CONSTITUTION: A wheel disk 6 for connecting a wheel hub 4 of a wheel and a wheel tire 8 of the wheel and having the conjugate fiber structure is formed of coating layers 10.1, 10.2 and an inner core 12, and the coating layer 10.1, 10.2 are formed of a conjugate fiber layered product 14 integrally wound with a side surface of the inner core 12 and the outside surface thereof. This hollow cassette 22 has the foaming filling material 24 in a hollow space thereof, and has an outer shape web 28 of the conjugate fiber, an outer shape side wall 30 and web extension parts 32, 34, and formed into a shape having a width capable of being enlarged outside in the radial direction so as to be arranged adjacent to each other in the periphery of the wheel hub 4. With this structure, structural hardness is improved, and mass production is enabled.
