PURPOSE:To lower the tilt rigidity of a bushing device while maintaining the transverse and longitudinal rigidities thereof at high values in order to enhance the drive feeling of an automobile, by filling a rubber member between inner and outer cylinders, and by filling a rubber member also between a slidable ring, a ring-like spacer and the inner cylinder. CONSTITUTION:An inner cylinder 23 is fitted on rotatably on a rotary shaft 22 fixed to a bracket 21 secured to an automobile body 15, and an outer cylinder 24 is fitted on the inner cylinder 23. Further, a first rubber member 51 is filled between the inner cylinder 23 and the outer cylinder 24, and a slidable ring 52 made in contact with the bracket 21 and a ring-like spacer 53 made in contact with one side surface 24a of the outer cylinder 24 are disposed among one side surface 51a of the first rubber member 51 and one side surface 24a of the outer cylinder 24 and the bracket 21. The inner diameters of the slidable ring 52 and the ring-like spacer 53 are made to be larger than the outer diameter of the inner cylinder 23, and thereby, a second rubber 54 is filled in a gap formed between the members 52, 53, 23. |
