PROBLEM TO BE SOLVED: To provide a parking assistance device capable of preparing a retreating track by a parking track in which the retreating track of an own vehicle is not brought into contact with a parking frame and a parking frame opposed space is minimized by considering the size of the parking frame. SOLUTION: The innermost peripheral track and the outermost peripheral track are memorized when an own vehicle turns from an optional reference point at the smallest turning radius. When driving operation that the own vehicle is retreated and is parked in a predetermined parking frame is assisted, width of the parking frame and a distance in a depth direction of the parking frame are detected and a central point coordinate in the width of the parking frame is set to a reference point 105. The reference point 105 is moved in the depth direction of the parking frames 101, 102 and a parking frame 102 direction in a range that they are not brought into contact with the parking frames 101, 102 to set a new reference point 105''. The smallest turning radius track 106'', the outermost peripheral track 107'' and the innermost peripheral track 108'' for parking the vehicle at the reference point 105'' are prepared and displayed.
