。[Scope of Claim for Utility Model Registration] In a hydraulic system for a working vehicle configured to drive a hydraulic actuator via a hydraulic pump mounted on an engine, a hydraulic filter and a hydraulic valve are provided for the hydraulic pump 3 mounted on the engine. The hydraulic filter 13 is integrally assembled to the valve casing 12 to form a hydraulic unit A that is directly connected to the hydraulic pump 3, and the suction for the hydraulic filter 13 of the hydraulic unit A is A hydraulic unit for a working vehicle, in which port a and spring chambers 9a and 10a of hydraulic valve A are formed in a state where they partially overlap to allow valve drain to escape to a suction port. The suction port a to the hydraulic filter 13 and the spring chambers 9a and 10b of the hydraulic valve are partially overlapped, such that the spring chambers 9a and 10a of the valve intersect with the suction port a. A hydraulic unit for a working vehicle as set forth in claim 1 of the utility model registration claim.
