The case is pressed against the retaining portion in the groove. Since the fixing screw is only screwed to the nut, in a state where the sensor case is not attached to the cylinder, that is, when only the sensor case is conveyed alone, the screw loosens due to vibration, impact, etc., There is a problem that the fixing screw falls off from the sensor case. Further, there is a problem in that the nut may also fall off due to the falling off of the fixing screw.

A sensor case 5 made of synthetic resin is mounted inside. On the outer surface side of the sensor mounting groove 3, there are formed retaining portions 4 for preventing the sensor case 5 from coming off with a space therebetween.

７の感知動作を視覚表示するランプである。As shown in FIG. 3, a detection circuit 6 is incorporated in the sensor case 5, and the detection circuit 6 is provided with a sensor element 7 for detecting the position of a piston head (not shown). This sensor element 7 is a magnetic sensing type sensor element, and a permanent magnet (not shown) is attached to the outer circumference of the piston head, and the piston position can be detected based on the magnetic sensing of the sensor element 7. Reference numeral 8 is a lamp for visually displaying the sensing operation of the sensor element 7.

It comes into contact with the retaining portion 4 of. Further, the sensor case 5 is formed with a downward housing hole 10,
A nut 11 is non-rotatably fitted in the hole 10. An insertion hole 12 is formed through the sensor case 5 so as to communicate with the threaded hole of the nut 11, and the insertion hole 12 is formed in the nut 11.
A fixing screw 13 is inserted through which the screw is inserted.

An annular projection 14 is integrally provided on the inner peripheral surface of the insertion hole 12 formed in the sensor case 5 so that the inner diameter thereof is slightly smaller than the outer diameter of the fixing screw 13. The protruding portion 14 is formed at a position where it abuts on the nut 11.

As shown in the figure, the thread of the fixing screw 13 bites into the protrusion 14 provided in the insertion hole 12, and resistance is imparted to the fixing screw 13. Then, the fixing screw 13 is tightened against the resistance, and the tip end thereof is brought into pressure contact with the bottom surface of the sensor mounting groove 3 of the cylinder case 1, so that the projecting portion 9 formed on the sensor case 5 is caused by the reaction force. The sensor case 5 is pressed against the retaining portion 4 of the sensor mounting groove 3, whereby the sensor case 5 is fixed in the sensor mounting groove 3. Even when the fixing screw 13 is loosened, the rotation of the fixing screw 13 is restricted by the resistance applied to the fixing screw 13.

ための別部品が不要であり、構成が簡単で製作が容易で
ある。Therefore, even when the sensor case 5 is not attached to the cylinder, that is, when the sensor case 5 alone is conveyed, the fixing screw 13 bites into the protrusion 14 and does not easily rotate, so that vibration during conveyance may occur. Screws will not loosen due to impact. Therefore, the fixing screw 13 is unlikely to drop off from the sensor case 5, and the nut 11 is also unlikely to drop off. Further, since the protruding portion 14 is scraped off by the thread of the fixing screw 13, there is no fear that the fixing screw 13 is screwed into the nut 11. Therefore, it is not necessary to form the protruding portion 14 part very accurately, and in addition, a separate component for preventing the fixing screw 13 from loosening is unnecessary, and the configuration is simple and the manufacturing is easy.
尚、この考案は前記実施例に限定されるものではなく、
例えば、突起部14を挿通孔12の中央部や、或いは上部に
設けたり、全体形状を環状以外の形状にしたりするな
ど、この考案の趣旨を逸脱しない範囲で各部の構成を任
意に変更して具体化することも可能である。The invention is not limited to the above embodiment,
For example, the protrusion 14 may be provided in the central portion of the insertion hole 12 or in the upper portion thereof, or the overall shape may be a shape other than an annular shape, and the configuration of each portion may be arbitrarily changed without departing from the spirit of the invention. It is also possible to materialize.

優れた効果を発揮する。As described in detail above, according to the present invention, there is no loosening of the fixing screw due to vibration, impact, etc., there is no fear that the fixing screw will fall out of the sensor case, and there is no fear that the nut will also fall out, and the configuration is simple. It has an excellent effect that it is easy to manufacture.
