A first MR sensor and a second MR sensor are a combination of a first magnetic resistance effect element pattern and a second magnetic resistance effect element pattern. The first MR sensor and the second MR sensor are disposed a prescribed distance apart such that, when the first MR sensor receives the greatest quantity of the magnetic field component of a magnet oriented parallel to the axial direction of a piston, the second MR sensor receives the greatest quantity of the magnetic field component of a magnet oriented parallel to the radial direction of the piston.

Hydraulic cylinder

A flow sensor includes a detector provided on a side surface of a body formed in a tubular shape. First and second passages formed in the interior of the body communicate with an introduction passage of the detector via first and second sensor passages. The first and second sensor passages penetrate through and open respectively on first and second projections, which project at predetermined heights from an inner circumferential surface of the body, communicating with the first and second passages. A fluid, which flows from the first passage and into the first sensor passage, after being guided to the introduction passage and the flow rate thereof detected by a detector, flows through the second sensor passage and into the second passage.
