Claims

[Claims for Utility Model Registration] 1. A predetermined position on the outer peripheral surface of the cylinder body of a pneumatic or hydraulic cylinder in which a piston equipped with a magnet is slidably fitted into the cylinder body made of a non-magnetic material such as aluminum. In the device for fixing a detector such as a reed switch that is activated by the approach of a magnet, a substantially U-shaped band made of a thin plate material with locking holes formed at both ends is fitted to the cylinder body, and The detector is provided with locking protrusions at both ends that lock into the locking holes of the band, and at least one of the locking protrusions has a sliding surface inclined with respect to the end of the band. A tightening screw is attached to the attachment body, and a tightening screw for pressing the detector against the outer circumferential surface of the cylinder body is screwed into a threaded hole provided through the center of the tightening body, and the tightening screw The tightening body is moved in a direction away from the detector by screwing, and the end of the band is engaged with the locking hole and the sliding surface of the locking protrusion, so that the end of the band is attached to the tightening body side. A pneumatic or hydraulic cylinder, characterized in that the detector is fixed to the outer circumferential surface of the cylinder body by sliding the band around the cylinder body and deforming the band so as to wrap it around the outer circumferential surface of the cylinder body. Fixing device for piston position detector. 2. A fixing device for a piston position detector of a pneumatic or hydraulic cylinder as claimed in claim 1, characterized in that an elastic body is interposed between the cylinder body and the band. 3. A practical use characterized in that the elastic body has a small thickness at a portion of the outer circumferential surface of the cylinder body located on the opposite side from the detector, and a thickness gradually increases at a portion close to the detector. A fixing device for a piston position detector of a pneumatic or hydraulic cylinder as claimed in claim 2.
