The utility model discloses a resilient oscillating device, which comprises two or more than two elastic tablets. Wherein, two ends of the elastic tablet are respectively connected with a basal body and a supporting body. All the connecting rims are parallel to each other, and the connecting form is triangle-shaped or parallelogram-shaped, or the like. According to request, a complicated structure could be derived when taking the utility model as a basic structure unit. The utility model is widely employed in situations with shock-absorbing or small-amplitude reciprocal oscillation, or the like, and has the advantages of portable structure, low cost and convenient maintenance.
