A rack-and-pinion steering apparatus in which a steering gear box for transmitting an operation of a steering wheel to road wheels includes a pinion operatively connected to the steering wheel, a rack bar which has a rack meshing with the pinion, and which is operatively connected to the road wheels, a housing slidably supporting the rack bar, a cylindrical rack guide slidably fitted into a guide hole formed in the housing, and a spring member causing the rack guide to abut on a rear part of the rack bar opposite to the rack by biasing the rack guide. A reaction force, which the rack guide receives from the rack bar, acts on the rack guide in such a way as to cause a rotational moment of the rack guide about an axis different from an axis of the rack guide.
