Abstract
To provides a technique capable of replenishing a working fluid smoothly while employing a method for replacing an atmospheric air with the working fluid. The reservoir apparatus ( ) includes a main reservoir ( ) having an inlet opening for feeding a hydraulic fluid, and an auxiliary reservoir ( ) connecting thereto through a piping ( ). There is a diagonally extending connecting pipe ( ) at the auxiliary reservoir ( ). There is a recessed portion ( ) at an opening portion ( ) of an inner periphery of the connecting pipe ( ). This recessed portion ( ), when compared with the case where there is no such a recessed portion, serves to enlarge the opening portion ( ) of the connecting pipe ( ) and more smoothly flow the replenishment working fluid at a nearby area of the opening portion ( ). By doing so, the opening portion ( ) of the connecting pipe ( ) can be more enlarged at the time of replenishment of the working fluid and formation of a film of the working fluid can be prevented at the opening portion ( ).
