1. A sensor mounting device for mounting, on an outer periphery of a cylindrical cylinder tube, a position sensor that detects a position of a piston of a hydraulic cylinder, the sensor mounting device comprising:
a fitting band; and a fastening screw that fastens the fitting band and that fixes the position sensor onto the cylinder tube, wherein the fitting band includes an annular portion wound and attached around the outer periphery of the cylinder tube, and first and second sensor holding portions formed on a first end and a second end of the annular portion so as to oppose each other, the first and second sensor holding portions pinching the position sensor from both sides, wherein the annular portion is formed of a metal belt-shaped band main body, the first and second sensor holding portions are formed by being provided with metal reinforcing plates in a superposed manner on an outer surface of first and second reinforcing plate attaching portions formed at a first end and a second end of the band main body so as to oppose each other, screw insertion holes for inserting the fastening screw are formed in the first and second reinforcing plate attaching portions and the first reinforcing plate provided on the first reinforcing plate attaching portion in a superposed manner, and a screw hole for screwing the fastening screw thereto is formed in the second reinforcing plate provided on the second reinforcing plate attaching portion in a superposed manner, wherein tip edges of the first and second reinforcing plate attaching portions of the band main body are formed in straight lines parallel to an axis of the annular portion, and wherein shapes of the first and second reinforcing plates in front view are rectangular, an inclined portion is at least formed at a distal end portion of the second reinforcing plate among the first and second reinforcing plates by inwardly bending the distal end portion along a folding line parallel to the axis of the annular portion, the tip edge of the reinforcing plate attaching portion among the first and second reinforcing plate attaching portions of the band main body including the reinforcing plate having the inclined portion provided in a superposed manner extends along the folding line of the inclined portion. |
