Abstract

A subframe structure includes an attachment bracket that is disposed between the second vibration-isolation device and rear cross member and that attach the second vibration-isolation device to the rear cross member, and four elastic bushings that floatably support the attachment bracket as to the rear cross member at four support points. A load input point where a load is input from an engine to the second vibration-isolation device is positioned within a region surrounded by the four support points in planar view.

First claim

What is claimed is:

1. A subframe structure for a vehicle, comprising:
a longitudinal member extending in a front-rear direction of the vehicle and a lateral member extending in a vehicle width direction, which are supported by a body frame of the vehicle;
a vibration-isolation device attached to a vehicular power plant of the vehicle and disposed on the lateral member to support the vehicular power plant in a vibration isolation manner, the vibration-isolation device having a load input point via which a vibration from the vehicular power plant is input to the vibration-isolation device; and
an attachment bracket for the vibration-isolation device, that is attached to the vibration-isolation device, and that is attached to the lateral member via a plurality of elastic members such that the lateral member floatably supports the attachment bracket and the vibration-isolation device, the plurality of elastic members being allocated at a plurality of support points which define a region surrounded by the plurality of support points,
wherein the load input point from the vehicular power plant to the vibration-isolation device is positioned within said region in planar view of thereof.

2. The subframe structure according to claim 1 ,
wherein the attachment bracket has a recess that allows a steering gearbox to be disposed therethrough and between the attachment bracket and the lateral member.

3. The subframe structure according to claim 1 , further comprising suspension arms which are attached attachment portions which are provided on both ends of the lateral member in the vehicle width direction.
