                                                               This patent presents an elevator arrangement, including
                                                              an elevator hoistway, an elevator car, which  is arranged
                                                              to travel in the elevator hoistway, a counterweight, a mov-

                                                              counterweight,  and supports them while  suspended from
                                                              the supporting platform, and a hoisting machine, which in-
                                                              cludes  a  device  configured  to  move  the  roping.  The  eleva-

         Since the sensor device 10 is tiltable, when the sensor face
         of the sensor device 10 is pressed against the wire rope 2,
         the sensor device 10 tilts, even if the sensor face is pressed
         against the wire rope 2 obliquely, and the wire rope 2 is thus
         easily brought into line contact with the sensor face.
           With  reference  to  figures  2  and  3,  four  tilt  regulating
         screws 32 are screwed into the bracket 22 near respective
         ones of the above-mentioned four bolts 31b with their dis-
         tal ends directed toward the back face of the sensor device
         10. By turning the tilt regulating screws 32, the amount of
         protrusion of the tilt regulating screws 32 from the bracket
         is adjusted. If the amount of protrusion of a tilt regulating
         screw 32 from the bracket 22 is enlarged, the back face of the
         sensor device 10 will contact the distal end of the tilt regulat-
         ing screw 32 when the sensor device tilts. The inclination of
         the sensor device 10, therefore, can be stopped at this point
         (no further inclination is allowed). The angle through which
         the sensor  device  10 is capable of tilting is thus adjusted
         using the tilt regulating screws 32. Naturally, it can also be
         arranged so that the sensor device 10 is incapable of tilting.  Figure 4: Diagrammatically presents an elevator arrangement, when
           The upper end of the above-mentioned bracket 22 is bent   the  elevator car is in use to serve passengers and/or to transport
         approximately at a right angle and extends horizontally in   freight.
