Auxiliary frame holding structure for holding auxiliary frame of i.e. passenger car, has rear bush including inner cylinder with region whose outside diameter is increased in proximity of lower end of region relative to other region

摘要

The structure has a front brush (100) with an inner cylinder (120) that includes a region (14) with large diameter. A rear bush (200) includes an inner cylinder (220) consist of a region (15) with large diameter, where outside diameter of the region is increased in proximity of a lower end of the region relative to other region. A middle region of the cylinders of the bushes has a horizontal cross-section with a dimension in a direction. A line extends from a yaw center of an auxiliary frame (10) to a central axis of the inner cylinders, where the direction is orthogonal to another direction.
