PURPOSE:To simplify the structure of small four-wheeled car and to facilitate manufacture by forming both side faces of chassis frame with side frame made of a pair of looped metal tubes while coupling both side frames with a cross member including a bottom plate and a front face plate for forming the floor. CONSTITUTION:Both side faces of chassis frame are formed with a pair of looped metal tubes 1A, 1A which are coupled through cross members 17, 17, front bumper 8, rear bumper 9, bottom plate 19 for forming the floor, roof, etc. Consequently the structure of chassis frame is simplified while manufacture is simplified because main parts are formed by bending a tubular member. |
