PROBLEM TO BE SOLVED: To obtain a tending working car capable of omitting a charge pump of a hydraulic non-stage transmission and readily performing a reduction in production cost, simplification, etc., of a hydraulic structure by connecting a hydraulic lifting and lowering pump for lifting and lowering a working machine to a specific hydraulic circuit. SOLUTION: This tending working car is provided with a hydraulic non-stage transmission 32 in a transmission case 6 and is obtained by connecting a hydraulic lifting and lowering pump 40 for lifting and lowering a working machine 29 to a charge hydraulic circuit 42 of the hydraulic non-stage transmission 32. In the process, an air-cooling fan 45 is preferably installed in a charge pump shaft 44 of the hydraulic non-stage transmission 32. Since the disused charge pump shaft 44 is thereby utilized to attach the air-cooling fan 45, the transmission case 6 and the hydraulic non-stage transmission 32 can readily be cooled simply by adding the air-cooling fan 45.
