A multi-stage adjustable spring resistant belly massager comprises a belly massaging pad, a push-pull rod, a resistance adjusting mechanism and two handle grips. A dispensation tip 20 is provided with a dispensation nozzle 19 attached to its distal end, a syringe having a hollow inner portion, that is connected to a proximal end of the dispensation nozzle 19, and a plunger 22 that is allowed to slide in the cylinder 21 of the syringe so that suction and discharge processes are carried out on the liquid by the dispensation nozzle 19. The system may be installed when constructing a building or when retrofitting an existing structure. Accordingly, the vehicle can support a wider automobile-like body which will not contact the road surface when the tilting frame tilts while navigating a turn.
