PROBLEM TO BE SOLVED: To provide an inexpensive cylinder capable of achieving expanding and contracting strokes of a rod in two stages with a simple structure with the small number of pieces of components and sealing parts. SOLUTION: A first piston 4 is slidably mounted in a cylinder main body 1, and the rod 6 is expanded and contracted in accompany with the sliding of the first piston 4. A second piston 7 is slidably mounted in the cylinder main body 1, and the first piston 4 can be stopped at a first stop position where the expanding and contracting stroke of the rod 6 is performed by a length of the first stage, and a second stop position where the expanding and contracting stroke is performed by a length of the second stage.
