Abstract: The present application provides a superimposed opposing wave spring that has a plurality of superimposed-layer wave spring units, wherein each layer in each superimposed-layer wave spring unit is formed by spirally bending around an axis into a wave shape, and waveforms of the respective layers in each superimposed-layer wave spring unit are arranged to overlap each other. At least one connection spring part, which connects two adjacent superimposed-layer wave spring units that are stacked one above the other, so that the two adjacent superimposed-layer wave spring units respectively have a first wave trough and a second wave crest that are abutting each other with opposing apexes, and respectively have a first wave crest and a second wave trough that are arranged across from each other in an upper position and a lower position.
