Zusammenfassung: | The invention provides a cylinder apparatus capable of improving the use convenience. The cylinder apparatus comprises: a protrusion (81) radially extending and arranged on any one of an inner peripheral surface of a cylinder and an outer peripheral surface of a piston rod; inclined parts (91,93) arranged on another one of the inner peripheral surface of the cylinder and the outer peripheral surface of the piston rod and capable of bunting against the protrusion (81) to make the cylinder rotate relative to the piston rod and guide the cylinder to the preset relative rotation position when the piston rod is changed at the maximum protrusion state; a locking part (87) arranged on another one of the inner peripheral surface of the cylinder and the outer peripheral surface of the piston rod and capable of bunting against the protrusion (81) to keep the protrusion (81) when the piston rod is changed at the maximum protrusion state, the cylinder and the piston rod rotate to the preset relative rotation position, an |
