Suspension structure for vehicle and method of manufacturing the same

A suspension structure for vehicle comprising at least a first plate and a second plate which are press-formed articles and comprising a body portion and a connecting portion to which a component for a vehicle suspension is connected,

• wherein the first plate includes a first body portion which constitutes the body portion, a first flat plate portion which is continuous with a principal surface of the first body portion and is bent and extends with respect to the principal surface, a first mounting surface which is formed at the first flat plate portion and is to come into contact with an outer surface of the component, and a flange portion which is continuous with the first flat plate portion, is bent with respect to the first flat plate portion, and extends toward outside of the principal surface of the first body portion,
• the second plate includes a second body portion which constitutes the body portion together with the first body portion of the first plate, a second flat plate portion which is continuous with a principal surface of the second body portion and is bent and extends with respect to the principal surface, and a second mounting surface which is formed at the second flat plate portion and is to come into contact with the outer surface of the component,
• a portion facing the first flat plate portion in the first plate is open such that the first mounting surface is formable by press working in a single state with the bent first flat plate portion,
• a portion facing the second flat plate portion in the second plate is open such that the second mounting surface is formable by the press working in a single state with the bent second flat plate portion,
• the body portion is constructed by bringing the first body portion of the first plate and the second body portion of the second plate face-to-face with each other,
• the connecting portion is constructed by bringing the first flat plate portion of the first plate and the second flat plate portion of the second plate face-to-face with each other with a space between the first flat plate portion and the second flat plate portion and spacing the first mounting surface and the second mounting surface,
• the flange portion of the first plate is overlaid on and bonded to the second body portion of the second plate so as to extend toward outside of the principal surface of the second body portion,
• the first body portion of the first plate is butted against an end of the second flat plate portion in the second plate along a direction in which the flange portion is overlaid on the second body portion of the second plate and is bonded to the second flat plate portion, and
• the end of the second flat plate portion in the second plate is butted against an inner surface of the first body portion of the first plate, the inner surface facing the second body portion.
