Abstract:
A wave washer is used for a shaft supporting device of an electric power steering system. The wave washer has an annular portion and six outward protrusions. The annular portion has first protrusions that protrude in a first axial direction and second protrusions that are formed so as to continuous with the first protrusions and that protrude in a second axial direction. Each outward protrusion protrudes from an outer periphery of the annular portion in a radially outward direction of the radial direction of the annular portion.
