PURPOSE:To prevent generation of impact and abnormal sound when the stroke of a rod is switched from the extending side to the contracting side in the upper mount of the hydraulic shock absorber of a suspension device. CONSTITUTION:An inner support 3 and a spring sheet 4 are stuck on the inside of an annular rubber member 21. An outer support 23 is fitted to the outside of the rubber member 21, and an upper support 23 is stuck to the rubber member 21, and lower support 24 is not stuck to the rubber member 21, and a flange part 25 is brought in contact with the lower end of the rubber member 21. A rod of a hyudraulic shock absorber is connected to a ball bearing 6 of the inner support 3, and the outer support 23 is connected to a car body by a stud bolt 9. The rubber member 21 becomes not to be easily bent because it is brought in contact with the flange part 25 in relation to the downeward displacement of the rod, while it becomes to be easily bent because it is separated from the flange part 25 in relation to the upward displacement. Accordingly, the stroke is switched after the downward displacement in the extending stroke, and the rod to be upwardly displaced is gradually decelerated, thereby generation of impact and abnormal sound can be prevented. |
