PROBLEM TO BE SOLVED: To provide a piston-cylinder unit capable of finding inner pressure of itself and indicating excessive pressure loss.SOLUTION: A piston-cylinder unit (1) includes a center longitudinal shaft (A), a first end (3), a cylinder (2) filled with fluid, a piston (13) slidably arranged in the cylinder (2) for dividing the cylinder (2) into a first operation chamber (11) which is far from the first end (3) and a second operation chamber (12) which is close to the first end (3), and a piston rod (8) arranged on the piston (13), passed through the first operation chamber (11), and communicated through the cylinder (2) with the outside in the form that it is sealed concentrically to the center longitudinal shaft (A) at a second end (6) facing the first end (3) by a guide/seal device (7), wherein a sensor device (14) is provided for directly or indirectly detecting the inner pressure of the piston-cylinder unit (1), in particular. |
