To provide a spring washer which is used for axially preloading anti-friction bearings, and which has an excellent spring effect and is manufactured easily.

The spring washer 1 includes an outer ring 2 and an inner ring 3 that is coaxially arranged with respect to the outer ring. An axis 4 is defined by the two rings. The outer and inner rings are connected through several resilient connection rods 5. Resilient cantilevered rods 6 are provided which extend from one of the rings in between the connection rods and which have a free end 7 at the other positioned ring. The cantilevered rods are axially bent up, and consequently, the free end has an axial offset.
