Japanese Patent JP2018071763
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transmission device for a working vehicle which can avoid the damage or the like of an O-ring by regulating the displaceable movement of a pressing piston while using a slide bearing.SOLUTION: A transmission device for a working vehicle comprises: a drive-side clutch body 87; a driven-side clutch body 86; energization means for elastically pressing the driven-side clutch body 86 to an engagement side at which the driven-side clutch body is made to approximate the drive-side clutch body 87; and a pressing piston 101 for operating the driven-side clutch body 86 to an engagement-release side at which the driven-side clutch body separates from the drive-side clutch body 87. An annular slide bearing receiver 70 for permitting the relative rotation of the pressing piston 101 and the driven-side clutch body 86 is interposed in an opposing point between the pressing piston 101 and the driven-side clutch body 86, and a co-rotation regulation mechanism for permitting the relative rotation between the driven-side clutch body 86 and the slide bearing, and suppressing the relative rotation between the pressing piston 101 and the slide bearing is arranged at the slide bearing receiver 70.SELECTED DRAWING: Figure 4
