摘要:
[Problem] An object is to provide a front suspension apparatus in which a front side of a suspension arm can be cut off from a subframe at the time of a small overlap collision without causing the complication of the structure and the formability.
[Means for Solution] A front suspension apparatus in which a lower arm 52 from which a front wheel is suspended is provided, and a front arm portion 53 and a rear arm portion 54 of the lower arm 52 are axially supported by axially supporting portions of a subframe 30 is characterized in that an axially supporting portion 59 of the front arm portion 53 is joined to the subframe 30 at a joined portion extending in a vehicle width direction, a joined portion extending in an up-down direction, and a joined portion extending in a front-rear direction, and a joining strength of a joined portion k in the front-rear direction is lower than a joining strength of the joined portion in the up-down direction.
