<p>A working fluid supply device (13) is provided with: a main body part (31) in which a housing chamber (30) is formed; a first piston (34) which is disposed in the housing chamber (30) and vertically advances and retreats; and a second piston (35) which is disposed on the underside of the first piston (34) in the housing chamber (30) and vertically advances and retreats. In the main body part (31), a first opening (37) through which a working fluid stored in a third region in the housing chamber (30) flows out of the housing chamber (30) by the upward movement of the first piston (34), and a second opening (39) through which the working fluid stored in a first region in the housing chamber (30) flows out of the housing chamber (30) by the downward movement of the second piston (35) are formed.</p> |
