There is provided a steering apparatus including a pinion communicating with an operation of a steering member, a rack shaft having a rack meshed with the pinion, and a support yoke resiliently coming into contact with the rack shaft, and being configured to convert rotation of the pinion into movement of the rack shaft in an axial direction in a meshing portion in which the pinion and rack mesh to each other. The steering apparatus comprises a detection unit for detecting a force applied to the support yoke to which a force acting on the meshing portion being transmitted from the rack shaft and a calculation unit for calculating a steering torque applied to the steering member based on the force detected by the detection unit, wherein the pinion and the rack are formed in helical gears.
