Claims

[Claims for Utility Model Registration] (1) A cylinder having an inlet and an outlet for working fluid at both ends, a piston provided in this cylinder so as to be able to reciprocate, and a hollow formed in this piston and a piston rod connected thereto. a guide pipe inserted into the hollow part in the axial direction and having one end fixed to the cylinder; a magnet provided on one of the peripheral wall of the hollow part and the guide pipe; and a reed switch provided on the other. A fluid pressure cylinder comprising: a plurality of magnets and a plurality of reed switches, each of which is arranged so as to be close to each other at a stop position of the piston. (2) The fluid pressure cylinder according to claim 1, wherein a plurality of magnets are provided on the circumferential wall of the hollow portion, and one reed switch is provided on the guide pipe. (3) The fluid pressure cylinder according to claim 1 or 2, wherein the magnet is held by a holding tube. (4) The fluid pressure cylinder according to any one of claims 1 to 3, wherein the reed switch is fixed within the guide pipe.
