Automobile body frame structure

摘要

An automobile body frame structure has an arrangement in which a suspension lower arm is supported in a front sub-frame and the front sub-frame is mounted on main frames. Among a front rubber bush joint and a rear rubber bush joint of the lower arm which are supported in the sub-frame, the axis of the rear rubber bush joint is in the vertical direction. Securing the front sub-frame to the main frame using a bolt that is used for mounting the rubber bush joint on the front sub-frame reduces the number of bolts, thereby reducing the number of assembling steps and the cost.
