PROBLEM TO BE SOLVED: To provide a vehicle driving support device capable of preventing contact of a vehicle body caused by inside-outside wheel difference by performing display for making a driver conscious of the inside-outside wheel difference when a vehicle is in turning cruise. SOLUTION: When the vehicle is in turning cruise, a virtual vehicle width "WA" which is a distance in a horizontal direction between trajectory of a predetermined portion "P1" of the vehicle which is most distant from the turning center of the vehicle in a horizontal direction and trajectory of an inner side rear wheel in a turning direction of the vehicle is calculated according to a steering angle "θST", while an angle between a line segment for connecting the predetermined portion "P1" and the turning center "OTC" and a straight line parallel to a rear wheel vehicle axis is calculated as a turning angle "θTRN". A middle point "P3" which exists at a distance (WA/2) from the predetermined portion "P1" is acquired using the turning angle "θTRN" and the virtual vehicle width "WA", and is displayed ahead of the driver by a head-up display.
