The present invention has: an inner cylinder (11) coupled to either one of a vibration generator and a vibration receiver; an outer cylinder (12) coupled to the other of the vibration generator and the vibration receiver; an intermediate cylinder (13) fitted on the inner circumferential surface of the outer cylinder (12); a main elastic body (14) for connecting the inner cylinder (11) and the intermediate cylinder (13); and stopper elastic bodies (15, 16) that are fixed to the intermediate cylinder (13) and that face the inner cylinder (11), there being interposed therebetween at least hollow sections (17, 18) formed in a direction orthogonal to the inner cylinder shaft direction so as to penetrate the main elastic body (14) in the inner cylinder shaft direction so that the stopper elastic bodies (15, 16) remain independent of the main elastic body (14). The stopper elastic bodies (15, 16) respectively have shaft direction stopper sections (15a, 16a) that protrude more in the inner cylinder shaft direction than the intermediate cylinder (13) and the outer cylinder (12). |
