PROBLEM TO BE SOLVED: To provide a supply pressure fluctuation suppression mechanism connected to a pressure device for changing fluid pressure stepwise and configured to suppress fluctuation in generated supply pressure on the basis of the fluid pressure.SOLUTION: A supply pressure fluctuation mechanism 25 is connected to a pressure increasing/decreasing machine 100 for changing the pressure of hydraulic oil stepwise. The supply pressure fluctuation suppression mechanism 25 includes a first pressure reduction valve 250, a second pressure reduction valve 251, and a direction switching valve 252 for selectively communicating one of the first pressure reduction valve 250 and the second pressure valve 251 with the pressure increasing/decreasing machine 100. The supply pressure fluctuation suppression mechanism 25 alternately communicates the first pressure reduction valve 250 and the second pressure reduction valve 251 with the pressure increasing/decreasing machine 100 by the direction switching valve 252, and suppresses fluctuation in supply pressure generated at each of the first pressure reduction valve 250 and the second pressure reduction valve 251 on the basis of hydraulic oil thereof. |
