A rack and pinion mechanism includes: a pinion shaft at which pinion teeth are formed; a rack shaft at which rack teeth to be engaged with the pinion teeth are formed; a pressing portion arranged at a side of the rack shaft opposite to a side of the rack shaft at which the rack teeth are formed and pressing the rack shaft toward the pinion shaft; a first elastic body biasing the pressing portion in a direction approaching the pinion shaft by an elastic restoring force; and a second elastic body biasing the pressing portion in a direction away from the pinion shaft by an elastic restoring force, and a first biasing force with which the first elastic body biases the pressing portion is larger than a second biasing force with which the second elastic body biases the pressing portion in an initial state.
