Abstract

See full text

A cylindrical vibration isolating device that prevents damage to a vibration isolating rubber and cracks in a welded portion of a sub-frame. The sub-frame mount comprises an outer cylinder, an inner cylinder connected by the vibration isolating rubber. Small and large diameter portions are provided on a lateral wall of a barrel portion of the outer cylinder. Between the small and large diameter portions is formed a step-like boundary portion. The height in the axial direction of the boundary portion changes in the circumferential direction and has a substantially mountain-like shape with a top projecting in the press fitting direction. A contact area of the large diameter portion contacting a mounting hole of the sub-frame is increased in accordance with an amount of the press fitting. Therefore, when the sub-frame mount is press-fitted into the mounting hole of the sub-frame, the press fitting load is gradually increased.
