A B S T R A CT A noise-preventing shock absorber adapted to suppress noise and absorb shock created by moving objects such as moving machine parts engaging mating surfaces and decelerating to zero vel- ocity within a short stroke or travel distance. The shock absorber in- cludes a unitary resilient member which is annularly shaped in plan view and provided with an axial opening, with the peripheral surface of the axial opening comprising an inner force-transmitting surface that is formed with a wavelike configuration in vertical cross section. An upper force-receiving shaft is disposed in the resilient member axial opening and has an exterior peripheral surface which is provided with a wavelike configuration in vertical cross section that mates with and is bonded to the wavelike inner force-transmitting surface of the resilient member. The resilient member is provided with a peripheral outer force-transmitting surface that is concentric with and axially offset downwardly from said inner force-transmitting surface, and which is provided with a wavelike configuration in vertical cross section. A lower force-receiving tube having an interior surface provided with a a wavelike configuration in vertical cross section mates with and is bond- ed to the wavelike outer force-transmitting surface of the resilient mem- ber. The shock absorber member can be used in a stacked arrangement to provide shock-absorbing and noise-suppressing units of various capacities,
