A rear wheel steering system (10) includes a rack shaft (11), a neutral position locking apparatus (20) that restricts the movement of the rack shaft (11) in a rack axis direction (X), and a pin-driving device (50) that drives a restriction pin (30). The neutral position locking apparatus (20) has the restriction pin (30) and a pin-receiving portion (40) formed in the rack shaft (11). The restriction pin (30) has a first pin-sidewall portion (33) slanted with respect to a pin axis (CP) and a second pin-sidewall portion (34) parallel to the pin axis (CP). The pin-receiving portion (40) has a first shaft-sidewall portion (41) that contacts the first pin-sidewall portion (33) when the position of the rack shaft (11) in the rack axis direction (X) is at a neutral position, and a second shaft-sidewall portion (42) that contacts the second pin-sidewall portion (34) when the position of the rack shaft (11) in the rack axis direction (X) is at a restriction position different from the neutral position.
