6 is fitted to form a sensor section 19, which is fixed to the upper plate 17 of the upper housing 8. However,
The sensor bracket 18 has a rectangular cross section, and a sensor retainer 21 is provided by making a cut with a desired size and width at an appropriate location on the bottom surface 20 and bending the sensor bracket 18 upward. In addition, the sensor 16
A locking groove 23 for fitting and locking the sensor retainer 21 of the sensor bracket 18 is cut in the bottom surface 22 of the sensor bracket 18 . Therefore, the sensor section 19
Insert the sensor 16 into the sensor bracket 18 from the open end 24 of the sensor bracket 18, lower the sensor holder 21, and move it forward.
Insert the sensor holder 21 into the locking groove 23 of the sensor 16.
is locked by spring back action, and the sensor 16 is fixed and held on the sensor bracket 18. At this time, an upper sensor retainer 25 may be arbitrarily provided at an appropriate location on the side edge of the sensor bracket 18, and the sensor 16 may be bent and locked into the upper locking groove 26 provided at the corresponding location to ensure fixation. can. Note that the upper sensor retainer 25 can be provided not only by protruding from the side edge, but also by simply making a notch, bending that part, and fitting it into the upper locking groove 26 that is deeply provided so as to match the corresponding part of the sensor 16. It is also possible to make them match.
