Abstract
A fluid pressure cylinder and a clamp device that, when an output member arrives at a prescribed position such as, in particular, an advance limit position or a retraction limit position, are capable of detecting the position of the output member on the basis of change of air pressure as, due to an opening/closing valve mechanism, the communication state of an air passage within the clamp main body is changed over together with the operation of the output member.
