`
`ABSTRACT
`
`A hydraulic transaXle comprises an axial piston hydraulic pump having a variable displacement,
`
`and a transaXle casing incorporating the hydraulic pump.
`
`The hydraulic pump includes a
`
`movable swash plate and a pair of trunnion shafts. The transaXle casing includes a pair of side
`
`walls, and includes a pair of casing holes each of which penetrates each of the side walls between
`
`an inside and an outside of the transaXle casing. The pair of trunnion shafts are passed through
`
`the respective casing holes. The swash plate is formed with a pair of swash plate holes in the
`
`respective side portions facing the respective side walls in the inside of the transaXle casing.
`
`Proximal end portions of the respective trunnion shafts are inserted into the respective swash
`
`plate holes. A distal end portion of one of the trunnion shafts projects from the corresponding
`
`casing hole to the outside of the transaxle casing.
