Abstract
A cylinder case includes a first main path communicating first port with an end surface, a second main path communicating a second port with the end surface, first and second front chamber paths respectively communicating a front chamber with the end surface, and first and second rear chamber paths respectively communicating a rear chamber with the end surface. A manifold block includes a first intermediate path communicating first and second manifold holes opened in an abutting surface with each other and a second intermediate path communicating third and fourth manifold holes opened in the abutting surface. The manifold block configured to be attached and fixed to the cylinder case such that the abutting surface is abutted against the end surface and a relative position of the abutting surface with respect to the end surface portion is capable of being selected from a first position and a second position.
