PURPOSE: To reduce the number of part items, and make a device compact by integrally forming a leveling valve of a cab and a magnetic valve by joining them together, and directly connecting an air introducing-deriving port of the leveling valve and a leveling valve side introducing-deriving port of the magnetic valve to each other. CONSTITUTION: A leveling valve B to hold a height of a cab of a vehicle in a neutral position and a magnetic valve C to open and close air, are integrally formed of a casting, and an air introducing-deriving port B3 of the leveling valve B and a leveling valve B side air introducing-deriving port C3 of the magnetic valve C, are directly connected to each other. An air introducing port B1, an air discharge port B2 and the air introducing-deriving port B3 to the magnetic valve C side, are arranged in the leveling valve B. Since the air introducing-deriving port B3 of the leveling valve B and the introducing- deriving port C3 of the magnetic valve C are directly connected to each other after they are integrally formed of the casting, an air tube-related part becomes unnecessary. |
