PURPOSE:To make improvements in the manufacturing efficiency of not only a standard machine type but also an optionally modified type, by attaching a subframe unit detachably to a main frame unit. CONSTITUTION:A body side unit A is made up of installing a body part including a driver's cabin 5, a rear body 6 or the like and a front wheel part consisting of a front wheel differential 12, front wheels 1 and a steering gear 20 or the like in a main frame unit 3a consisting of a symmetrical pair of main frames 18 among underframes 3 and plural cross frames 19. And, those of an engine 7, a transmission case 8 and a rear wheel differential 9 being solidly coupled together as one body are solidly attached to a subframe unit 3b consisting of a symmetrical pair of short frames 22 and cross frames 23 via coupling devices 24a and 24b, and a rear axle 10 is coupled with a plate spring and supported in a state of regulating an interval between wheels 2, thus a rear wheel side unit B is constituted. |
