Abstract:
Provided is a hydraulic power transmission device enabling to minimize a pressure loss in an oil passage downstream from a piston chamber of a hydraulic clutch, and to properly prevent reduction in transmission torque capacity in the hydraulic clutch. Left and right pressure regulating valves ( 8 L,  8 R) regulating pressure of oil flowing out from piston chambers ( 59 L,  59 R) of left and right clutch devices ( 5 L,  5 R) are arranged adjacent to a downstream of the piston chamber ( 59 ). This can shorten an oil passage from the piston chamber ( 59 ) to the pressure regulating valve ( 8 ) and minimize pressure loss in the oil passage. Due to better flexibility of arrangement of the pressing load receiving member ( 82 ) receiving a pressing force (thrust) of the piston member ( 57 ), thrust efficiency of the hydraulic piston ( 57 ) improves to properly prevent reduction in transmission torque capacity in the hydraulic clutch ( 5 ).

Claim (Index 3):
The hydraulic power transmission device according to  claim 2 , wherein on an outer diameter side of an opening of the first through hole or on an outer diameter side of an opening of the second through hole, a projection axially projected to cover the outer diameter side of the opening.
