Zusammenfassung:PROBLEM TO BE SOLVED: To inhibit changes in a length of a gap between a head member and a piston which are caused by bolt fastening.SOLUTION: Fastening bolts (70) fasten a first head member (61), a first cylinder (51), and a second head member (62). The first head member (61) is disposed at one end side in an axial direction of the first cylinder (51). A protective groove (80) is provided on an end surface of the first head member (61) which contacts with the first cylinder (51). The protective groove (80) is formed closer to a center of the first cylinder (51) than the fastening bolts (70), and its groove width (W) is shorter than its groove depth (D).SELECTED DRAWING: Figure 2 【課題】ボルト締結によるヘッド部材とピストンとの間の隙間長さの変動を抑制する。【解決手段】締結ボルト（70）は、第１ヘッド部材（61）と第１シリンダ（51）と第２ヘッド部材（62）とを締結する。第１ヘッド部材（61）は、第１シリンダ（51）の軸方向一端側に配置されている。第１ヘッド部材（61）の第１シリンダ（51）に接する端面には、保護溝（80）が設けられている。保護溝（80）は、締結ボルト（70）よりも第１シリンダ（51）の中心に近い側に形成され、その溝幅（W）がその溝深さ（D）よりも短くなっている。【選択図】図２
