Abstract
A hydraulic controller includes: a pair of liquid chambers; and an on-off valve capable of opening and closing a flow channel on the side of the liquid chamber with a higher hydraulic pressure out of the pair of liquid chambers. The flow channel can provide communication between the pair of liquid chambers. A baffling device is provided in the liquid chamber with a lower hydraulic pressure, to baffle hydraulic fluid flowing from the liquid chamber with the higher hydraulic pressure. Thus, it is possible to reduce operating noise resulting from operation of the on-off valves.
