Abstract:
A cylinder tube and attachment structure for attaching a position-detecting sensor to said cylinder tube for detecting a position of a piston accommodated in a cylinder chamber of said cylinder tube, said attachment structure for said position-detecting sensor comprising:said position-detecting sensor including a detecting element for sensing a magnetic field of a magnet installed on said piston; and a sensor attachment mechanism for holding said position-detecting sensor so that said position-detecting sensor is separated by a predetermined spacing distance from an outer side surface of said cylinder tube, wherein said sensor attachment mechanism includes a rail member which is secured to said outer side surface of said cylinder tube, and a holder which holds said position-detecting sensor and which is provided slidably along said rail member, and wherein chamfered sections, each of which is chamfered with a predetermined radius of curvature, are formed for said rail member and said holder.
