PROBLEM TO BE SOLVED: To provide technology for adjusting static/dynamic vibration ratios in a cylinder axial direction and in a torsional direction to be desired values and technology for improving the shaping stability of a rubber elastic body. SOLUTION: This vibration absorbing device 10 comprises an inner cylinder body 11, an outer cylinder body 12 provided on the outer periphery of the inner cylinder body 11 coaxially with the inner cylinder body 11, and the rubber elastic body 13 arranged between both cylinder bodies 11, 12 for connecting both cylinder bodies 11, 12 to each other. At either end of the rubber elastic body 13 in the cylinder axial direction, a currant portion 15 is arranged throughout the periphery in the cylinder peripheral direction. On the currant portion 15 at each end of the rubber elastic body 13 in the cylinder axial direction, a resin spring body 16 integrated with the outer cylinder body 12 is provided throughout the periphery in the cylinder peripheral direction. At the center of the outer peripheral face of the rubber elastic body 13 in the cylinder axial direction, a recessed portion 19 is provided throughout the periphery in the cylinder peripheral direction. A rigid ring 20 is fitted into the recessed portion 19. COPYRIGHT: (C)2007,JPO&INPIT |
