Abstract

See full text

A flow path control device includes: an on-off valve for opening or closing a flow path through which fluid flows from a first chamber to a second chamber; a control valve which controls the opening and closing of the on-off valve by transiting between a first state and a second state; and a push rod which includes a rod-shaped portion of which one end is pressed and moved to the other side and the other end causes the control valve to transition from the first state to the second state and a protruding portion which protrudes radially outward of the rod-shaped portion from an outer peripheral surface of the rod-shaped portion so as to receive pressure of fluid flowing from the first chamber to the second chamber.
