To provide a gearbox component and a preform of the gearbox component.SOLUTION: A gear box component having a curved part on an outer surface is formed of a fiber-reinforced resin composition in which a reinforcing fiber having an average fiber length of 0.5 mm or more are dispersed in a resin material. At least some of the reinforcing fibers, for example, a reinforcing fiber 155 at a root part 157 of a boss 91, are oriented across the curved part. A preform of the gear box component before being filled with resin is configured to include reinforcing fibers having an average fiber length of 0.5 mm or more. At least a part of the reinforcing fibers is oriented across the curved part in the curved part formed on the outer surface of the gear box component.SELECTED DRAWING: Figure 10
