Subframe structure for vehicle

A subframe structure for a vehicle attaches a lower arm to a cross member extending in the vehicle width direction, the lower arm extending in the vehicle width direction and being configured to move rotationally about a predetermined rotational axis to support a knuckle such that the knuckle can be displaced in the vehicle height direction. The subframe structure includes a cylindrical bush whose central axis is aligned with the rotational axis. The cross member has an arm attaching hole that retains the bush such that the bush is rotatable about the rotational axis. The lower arm is fixed to the bush at a position on the rotational axis. The arm attaching hole opens downward in the vehicle height direction. The cross member retains the bush such that a part of the outer surface of the bush protrudes downward in the vehicle height direction beyond a lower end portion.
