PROBLEM TO BE SOLVED: To provide a fluid damped bushing of a simple structure by providing a metallic inertia track plate in a space between recess of a bushing including a fluid, and providing a metallic cylinder which is short in a longitudinal direction on both ends of a rubber elastic element in the longitudinal direction at intervals in the longitudinal direction. SOLUTION: An annular elastomeric body 14 has a pair of recesses 16, 18 spaced each other, and one more recess 20 connecting to the recesses 16, 18 with a fluid flow path. The fluid flow restricted between the recesses 16, 18 is supplied by an inertia track plate 22 through the recess 20. The inertia track plate 22 is tightly fitted in the recess 20, and has a restricted meander flow passage 24 in the exterior surface thereof. The meander flow passage 24 is connected to the recesses 16, 18 with the fluid flow path. The inertia track plate 22 has a arch shape in a fixed direction, and relative end pieces 22a, 22b are extending to the recesses 16, 18, thereby maintaining the inertia track plate 22 relatively at a correct position with respect to the recesses 16, 18. |
