PURPOSE: Structure of a magnetic valve for a lifting system is provided to be adapted for parking over a slant road without worrying about discharge of battery. CONSTITUTION: An output port(2) outputs pneumatic pressure supplied to an input port(1) and a valve body(4) is equipped with an exhaust port(3) exhausting pneumatic pressure returning to the output port. A valve spool(5) communicates the input port and with the output port by sliding in a linear direction from the valve body to switch over the communicated state between the output port and the exhaust port. Plural supply instruments of spool actuating force feeding valve for applying spool-actuating-force to the valve spool(5) with electricity applied, are installed in the valve body. With the magnetic valve structure, an axle is maintained in a lifted state continuously without additional power consumption during parking on a slant road so that a stable parking state is secured.
