PURPOSE:To improve the durability of resilient member by providing a stopper section of specific height at the pocket section for encapsulating non-compressive fluid thereby preventing deformation of resilient member more than predetermined amount. CONSTITUTION:Plural pocket sections 30 for encapsulating non-compressive fluid are provided in a resilient member 8 inserted between an inner tube metal 4 and an outer tube metal 16. A stopper member 6 having a stopper section 24 of specific height projecting into said pocket section is inserted and secured to the inner tube metal 4 while an orifice 26 communicatable between the pocket sections 30 is formed at the boss section 22 of the stopper member 6. Upon contact of the stopper section 24 against the outer tube metal 16, further deformation of the resilient member 8 is prevented resulting in improvement of the durability of the resilient member 8. |
