Abstract

[Problem] To achieve large energy absorption by a subframe structure by deforming front-rear frames into a Z shape in vehicle side view in the event of a front-end collision. [Means for Solution] The subframe structure includes: a pair of front-rear frames 31 each mounted with a lower arm 21; and a transverse member 32 connecting front portions of the front-rear frames 31, wherein the front-rear frames 31 each include a rear horizontal portion 39a, an inclined portion 39b extending frontward and substantially upward from a front end of the rear horizontal portion 39a, and a front horizontal portion 39c extending frontward from a front end of the inclined portion 39b, the transverse member 32 is jointed at first and second ends thereof to the front horizontal portions 39c respectively corresponding to the first and second ends, a rear end 39f of the front horizontal portion 39c is configured to be positioned frontward of a front end 10f of an engine 10, and the front-rear frames 31 are configured to deform into a Z shape in vehicle side view in an event of a front-end collision and thereby absorbing energy of the front-end collision.
