To provide a transmission capable of accomplishing simplification of an operation oil feeding structure to a hydraulic servo mechanism capable of ensuring a free space between a drive source and it and changing/operating a volume adjustment mechanism of HST while narrowing vertical width of the HST as much as possible, and a charge oil feeding structure to the HST.
The HST is supported on a transmission case connected to a pair of main frames so as to leave from the drive source, and a portion corresponding to a pump shaft of a HST oil passage is made to a vertical portion. The hydraulic servo mechanism for operating the volume adjustment mechanism is provided at a side opposite to a motor shaft in a vehicle width direction making the pump shaft as reference. The charge oil to the HST oil passage is taken out from the servo oil passage for feeding the operation oil to the hydraulic servo mechanism.
