PROBLEM TO BE SOLVED: To constitute a static hydraulic continuously variable transmission for traveling so that a swash plate of a hydraulic motor is properly operated, when a hydraulic pump and the hydraulic motor are constituted in a variable displacement type.SOLUTION: A working vehicle includes hydraulic actuators 46-49 for operating a swash plate 24a of a hydraulic motor 24, and is constituted such that first pilot pressure branched off from a high pressure side oil passage 25 acts on the hydraulic actuators 46-49 so that the swash plate 24a of the hydraulic motor 24 is operated to the low speed side, and second pilot pressure branched off from a charge pump 27 acts on the hydraulic actuators 46-49 so that the swash plate 24a of the hydraulic motor 24 is operated to the high speed side. |
