Abstract
Provided are an electric power steering system and a vehicle steering system each including rack-and-pinion mechanisms (A,B). A rack shaft () has a first rack (A) and a second rack (B) that are formed on the axially opposite sides of the axial center of the rack shaft (). The first rack (A) has a regular pitch p between rack teeth, the second rack (B) has a regular pitch p between rack teeth, and these pitches p are equal to each other. A predetermined difference is set between the phase of gear teeth engagement between a first pinion shaft (A) and the first rack (A), which constitute the first rack-and-pinion mechanism (A), and the phase of gear teeth engagement between a second pinion shaft (B) and the second rack (B), which constitute the second rack-and-pinion mechanism (B).
