<p>A working fluid storing device of an electrical discharge machining apparatus having a working bath (2) in which working fluid (5) supplied by a working fluid supplying means (6) is stored, an object (4) to be worked is placed in the working fluid (5), and an opening (2a), a door (12) for opening/closing the opening (2a), and a sealing member (10) that seals the space between the working bath (2) and the door (12), comprising supporting plates (13) in which slots (13a) elongated in vertical direction are formed, fixing means (14) that fix the supporting plates (13) to the door (12), and arms (15) that are pivotally supported at both of their ends by the working bath (2) and the supporting plates (13). Since the door (12) can be held in a position where the lower end part of the opening (2a) of the working bath (2) is concealed and in a position where the lower end part of the opening (2a) is exposed, it is possible to easily perform maintenance and replacement of the sealing member (10).</p> |
