An outer circumferential surface of a trunnion shaft includes a sliding contact region that has a circular arc shape as viewed along a slanting axis line and is substantially brought into contact with an inner circumferential surface of the bearing portion in a rotatably sliding manner, and at least one suction groove that forms a pocket portion between the suction groove and the inner surface of the bearing portion. The pocket portion is opened to an inner space of housing on at least one side in an axis line direction of the trunnion shaft.

Variable displacement axial piston device

An axle driving apparatus has in a housing a hydrostatic transmission with a variable displacement type hydraulic system having a slantingly movable swash plate. In one embodiment, the movable swash plate is manually slantingly operable. A leg member integrally extends from an inner wall of the housing, a lid for closing an opening of the housing, or a center section. The leg member has a support portion for supporting a shaft provided on an axis of rotation of the movable swash plate. Accordingly, the movable swash plate is suspended in the housing for slanting or pivoting movement.

Axle driving apparatus

An axle case, housing therein axles and a transmission for driving the axle, provided with a mount boss for being mounted to case mounting portions provided on a body frame of a vehicle and having insertion bores for mounting bolts, and including vibration isolating members which are each fixedly positioned on each mount boss and are provided with a portion positioned thereon and a portion extending into the insertion bore, so that, when the mount boss is coupled with the case mounting portion, the portion of the vibration isolating member positioned on the mount boss contacts with the case mounting portion. Thus, the axle case and body frame can be simply coupled with each other by using the vibration isolating members. The axle case is preferably divided vertically into an upper and a lower portion through a horizontal joint surface. When the axle case is molded, the insertion bores for the mounting bolts for mounting the mount boss can simultaneously be cast into the axle case, whereby there is no need for machining the axle case after it is molded.
