Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multistage stroke type fluid pressure cylinder and an actuator each of which has simple configuration thereby enabling the number of components thereof to be reduced and can be reliably assembled.SOLUTION: An actuator 12 comprises a multistage stroke type fluid pressure cylinder 10. The fluid pressure cylinder 10 comprises an integrally formed cylinder body 18; a closing member for closing openings of cylinder holes 20a, 20b; intermediate rod covers 84a, 84b which are arranged among the first pistons 78a, 78b and the second pistons 80a, 80b and through which the pressing rods 82a, 82b pass; and latching members 134a, 134b for latching the intermediate rod covers 84a, 84b to the cylinder body 18.SELECTED DRAWING: Figure 3 【課題】簡易な構成で部品点数の削減を図ることができ、且つ確実に組み立てることができる多段ストローク式の流体圧シリンダ及びアクチュエータを提供する。【解決手段】アクチュエータ１２は、多段ストローク式の流体圧シリンダ１０を備える。流体圧シリンダ１０は、一体成形されたシリンダ本体１８と、シリンダ孔２０ａ、２０ｂの開口部を閉塞する閉塞部材と、第１ピストン７８ａ、７８ｂと第２ピストン８０ａ、８０ｂとの間に配設されて押圧ロッド８２ａ、８２ｂが貫通する中間ロッドカバー８４ａ、８４ｂと、中間ロッドカバー８４ａ、８４ｂをシリンダ本体１８に係止する係止部材１３４ａ、１３４ｂと、を備える。【選択図】図３
