Abstract:
A drainage device of an electric power steering system has a drain case and a drain valve. The drain case has a groove portion formed in a peripheral edge portion of a case inlet. The drain valve has a main body, and a flange disposed so as to face the case inlet. The flange has a bulged portion bulged toward the case inlet, and an annular seal portion. When the seal portion is brought into tight contact with the peripheral edge portion of the case inlet, the drainage device is placed in a valve closed state to form an annular space between the groove portion and the seal portion. When the seal portion is elastically deformed to form a gap between the seal portion and the peripheral edge portion of the case inlet, the drainage device is placed in a valve open state.
