Document Type and Number:
Japanese Patent JP2013204801
Kind Code:
A
Abstract:

To provide a cylindrical antivibration device having a novel structure and a method for manufacturing the same, capable of restricting the amount of displacement of both an inner shaft member and an outer cylindrical member on both sides in a direction perpendicular to an axis and an axial direction with the reduced number of components, and also capable of achieving easiness of control and conveyance.

Dividing parts 42 are provided successively over a whole axial length of an outer cylindrical member 18 to divide the outer cylindrical member 18 in a peripheral direction. The outer cylindrical member 18 is provided with a storage part 30 extending in an axial direction away from a part with a body rubber elastic body 20 fixed, and is formed with a storage recessed part 26 opened into an inner peripheral surface of the storage part 30. Further, a stopper member 14 fixed to an inner shaft member 16 is arranged in the storage recessed part 26. A stopper means in a direction perpendicular to an axis is composed by allowing the stopper member 14 to abut on a bottom wall part of the storage recessed part 26, and also a stopper means in the axial direction is composed by allowing the stopper member 14 to abut on an axial wall part of the storage recessed part 26.
