いる。2. Description of the Related Art In a hydraulic cylinder, for example, a pneumatic cylinder, as shown in FIG.
A head 102 and a head 103 are respectively arranged at both ends of the head, and a tie rod 104 is inserted into the heads 102 and 103 and screwed with a nut. In order to detect the position of the piston of the pneumatic cylinder, a reed switch 105 is fixed on the outer periphery of the cylinder tube 101.

ている。Conventional methods for mounting a reed switch on a cylinder tube include a method of tightening and fixing the reed switch with a band wound around the outer circumference of the cylinder tube, and Japanese Utility Model Publication No. 60-24969 and Japanese Utility Model Publication No. 63-1.
As disclosed in Japanese Patent No. 4084, a method of attaching a reed switch to a tie rod using a special attachment is known.

た。The method of tightening with a band has a problem that the cylinder tube is distorted because the cylinder tube is tightened with the band. Also, in the method using the mounting fixture, the diameter of the cylinder tube differs depending on the application, and the diameter of the tie rod that tightens both ends of the cylinder tube may differ,
The reed switch mounting bracket cannot be shared, and a separate dedicated reed switch mounting bracket is required. That is, there is no compatibility between the reed switch mounting tools, and if the diameter of the cylinder tube or the tie rod is different, it is necessary to prepare a reed switch mounting tool of another size. In addition, there is play between the through holes of both heads and the tie rods, and the positional relationship between the tie rods and the cylinder changes with each assembly. Therefore, it is necessary to make a large adjustment allowance for the adjustment screw for mounting the reed switch.
