Abstract
A steering system includes a rack housing and a drainage device. The drainage device has a drainage case, and a drainage valve made of a resin. The drainage case has a case inlet port communicated with a housing space of the rack housing, case outlet ports communicated with the outside of the rack housing, a drainage space communicated with the case inlet port and the ease outlet ports, and a convex portion. The drainage valve has a valve body inlet port portion, and a valve body outlet port portion that interrupts communication between the case inlet port and the case outlet ports when the valve body outlet port portion comes into contact with the convex portion.
