摘要： PROBLEM TO BE SOLVED: To make a spring constant approximate by solving the problem that when a fuel tank is supported on a car body through a cushion rubber provided with a projection having an expanding slot, a difference in spring between longitudinal direction and lateral direction becomes larger. SOLUTION: A first projection 31 and a second projection 34 are provided on a vibration isolation cushion rubber 30 interposed between the fuel tank 10 and a floor panel 20, and a longitudinal expanding slot 32 and a lateral expanding slot 35 are provided to be orthogonal to each other on the respective apexes. The slot wall 36 of the second projection is liable to fall and the slot wall 33 of the first projection 31 is hard to fall due to the longitudinal external force. To the contrary, the slot wall 33 of the first projection 31 is liable to fall and the slot wall 36 of the second projection 34 is hard to fall due to the lateral external force. Therefore, the spring ratio of the longitudinal direction to the lateral direction becomes small so that the spring constants in the respective directions approximate to each other.

摘要： PROBLEM TO BE SOLVED: To provide a two resonance-type liquid sealing vibration isolation device that generates two resonances with only a damping orifice and a movable membrane with attached leg, and without providing an idle orifice, a valve mechanism for opening/closing same, etc.SOLUTION: A damping orifice 14 and an elastic partition 30 are provided in a partition member 11 that partitions a main liquid chamber 12 from a secondary liquid chamber 13. A leg 35 is integrally protrudingly formed to protrude from the lower surface of a movable membrane 31 provided in the central part of the elastic partition 30 and is pressed perpendicularly against a stopper surface 48, which is the upper surface of the bottom 46 of a frame member 40. Forming a third liquid chamber 50 between the outer circumference of the leg 35 and a supporting wall 44 and pressing the lower surface 38 of the leg 35 against the stopper surface 48 seals the third liquid chamber 50, traps the hydraulic fluid, and increases the internal pressure. When the leg 35 is separated from the stopper surface 48, the third liquid chamber 50 opens into the secondary liquid chamber 13 and the hydraulic fluid flows out of the third liquid chamber 50. A resonance is generated with the flowing of the hydraulic fluid, which results from the outflow, generating a second resonance that differs from a first resonance that results from the damping orifice.

摘要： PROBLEM TO BE SOLVED: To improve durability of a mass protrusion in an engine mount for suppressing the surging phenomenon by providing the mass protrusion on an approximately angle-shaped elastic leg connecting an inner cylinder to an outer cylinder, and resonating the mass protrusion in a resonance frequency region of the elastic leg.
SOLUTION: The mass protrusion 5 is arranged eccentrically upward outside an inside constraining line L1 and an outside parallel line L2 and near an outside upper constraining portion 7a. Thus, when the inner cylinder 2 is moved up and down with vibration, great force is hardly applied to the mass protrusion 5, therefore improving the durability of the mass protrusion 5 while reducing distortion therearound.
