PROBLEM TO BE SOLVED: To provide a low-cost and high-durability pressure-measuring apparatus capable of being housed inside a low-level space. SOLUTION: The pressure measuring apparatus includes a base part having a support surface; a movable member having a pressure sensor; a rod-like member in which a screw is formed in its surface; a driving means for driving the axial rotation of the rod-like member; a first slide member helically engaged with the rod-like member and movable along the support surface in one axial direction by the axial rotation of the rod-like member in one direction; a second slide member helically engaged with the rod-like member, at a position separated from the first slide member and movable along the support surface in the other axial direction by the axial rotation of the rod-like member in one direction; a first lift member having one end part oscillation-freely connected to the first slide member and the other end part oscillation-freely connected to the movable member; and a second lift member with one end part oscillation-freely connected to the second slide member, and the other end part oscillation-freely connected to the movable member.
