Provided is a suspension subframe structure that can activate a load path using an extension frame in an impact while avoiding increase in vehicle weight and also enables a suspension subframe to disengage from a vehicle body when an impact load is too large to be absorbed by the extension frame alone. The suspension subframe structure of the present invention includes a suspension subframe 110 that supports a suspension member 60 for a front wheel. The suspension subframe 110 includes: a body 111 that transmits an impact load input from a vehicle front side toward a vehicle rear side; a fixed portion 124 disposed near the body 111 and fixed to a vehicle body; and a connection portion 121 connecting the fixed portion 124 to the body 111. The connection portion 121 is provided with fragile portions 121f, 122g having a lower strength against a load in a vehicle front-rear direction than the body 111 and the fixed portion 124.
