A system for adjusting the pressure of a vehicle is provided to install leveling device in an arm head and detect the variation of current values to control the leveling device according to the variation of the current values so that the tensile force of the spring is adjusted. A spring(17) used to prevent a wiper, which has one end portion fixed to a wiper retainer(13), from being damaged is coupled to an actuating rod(21) of a leveling device(20) attached to an arm head(12) by using a hook(22). The operational current of a wiper motor is detected and the actuating rod(21) appears and disappears according to the variation of the operation current, so that the tensile force of the spring(17) is adjusted. |
