To provide a hand stocker with a simple structure. A hand stocker (10) housing a hand (35) for attaching on an actuator (2) includes a housing board (17) that houses the hand in a hung state and includes a hanging mechanism (70) hanging the hand on a board surface (17a) facing the hand. The hanging mechanism includes: a hooking member (22) that extends in a horizontal direction from the board surface to engage with a hanging portion (40) disposed in the hand; a pressing member (23) that prevents the hand hung on the hooking member from moving to a direction separating from the board surface; and a supporting member (24) that restricts the hand hung on the hooking member from moving to a direction approaching the board surface. The hand is sandwiched between the pressing member and the supporting member and housed.

A fluid pressure producing method reduces fluctuations in the pressure of a fluid (F2) pressurized using a plunger (261,262) driven by applying the pressure of a working medium (F1) to a double-acting piston (23). The method includes switching a moving direction of the piston (23) when detecting the piston reaching a movement end, operating the working medium pump (11) to discharge the working medium (F1) at a maximum flow rate while the load is less than the load limit after the moving direction of the piston (23) is switched, and detecting a pressure of the fluid (F2) and feeding back the detected pressure of the fluid and performing feedback control of the pressure of the fluid to eliminate a difference between the pressure of the fluid and a target pressure of the fluid.
