A vibratory plate compactor comprises a balancing frame mounted on support bumpers with a slide-crank vibration exciter, whose cranks by means of drive elastic links are connected to a working body in contact by means of non-linear elastic suspensions with the balancing frame. Each non-linear elastic suspension is made in the form of a rubber stepped barrel-shaped buffer with vertical holes coaxially arranged under a rubber shock absorber and mounted in a metal ring with a barrel-shaped gap, which is smaller than the transverse deformation of the lower step of the buffer compressed by a device consisting of a threaded rod screwed into the balancing frame, a clamping flange and a nut, and passes through the inner holes of the shock absorber and buffer.
