Abstract: A vehicle lock device having an approximately U-shaped fixing portion is contained so as not to be seen from the exterior. An approximately U-shaped fixing portion is disposed within a containing portion formed on a rear fender so as to be longer in the longitudinal direction. A lock portion longer in the vehicle width direction is overlapped on the fixing portion so as to cross the fixing portion. The fixing portion and the lock portion are fixed to a hook of a cross-plate and stays of seat rails by means of a fixture. A seat is then mounted on the seat rails. The vehicle device can be thus contained so as not to be seen from the exterior.
