Occasion in the sensor housing 2 with the 2nd embodiment places cylinder body 1 elongated slot 3, the integral body that makes sensor housing 2 is entrenched in the elongated slot 3 from the one end with the head 8b of outside thread member 8, if in elongated slot 3, slide into destination locations (detection position of piston), then screw-driver is put into the straight groove 8c of outside thread member 8, with screw-driver outside thread member 8 is rotated to the reverse direction that is head 8b rises relative to nut 9 and tapped hole 2h, as shown in figure 23,2g is close under the state on elongated slot 3 bottom surfaces below the teat 2d of sensor housing 2, the both sides shoulder 3c crimping of the plane of inclination of teat 8b and elongated slot 3 and reverse fastening outside thread member 8.
Therefore the head 8b of outside thread member 8, even the height of the shoulder 3c of the sectional shape of elongated slot 3, particularly its inner face is different with shape, also can deal with owing to arbitrary occasion in the 1st and the 2nd embodiment all is that circular cone is trapezoidal.Figure 24～Figure 26 is that example is represented this situation with the 2nd embodiment.
Under the situation of Figure 24, the cross section after elongated slot 3 is cut by the opening portion 3a of rectangular cross-section and circular upper is that the inner 3b of groove of C shape constitutes, and the upper end part, both sides of the inner 3b of this groove is shoulder 3c, and this shoulder 3c goes up the plane of inclination of the head 8b of crimping outside thread member 8.
Under the situation of Figure 25, elongated slot 3 is made of the inner 3b of groove that the opening portion 3a and the cross section of rectangular cross-section is U-shaped, be formed with the shoulder 3c of the level that is seen as from its center in the upper end, both sides of the inner 3b of this groove, the plane of inclination of the head 8b of crimping outside thread member 8 on this shoulder 3c.
Under the situation of Figure 26, elongated slot 3 is identical with the situation of Figure 24, the inner 3d of groove that is C shape by the opening portion 3a and the cross section of rectangular cross-section constitutes, though the upper end part, both sides of the inner 3d of this groove is the shoulder 3c of a circular arc part, but compare with Figure 24, shoulder 3c is highly higher because the inner 3d of groove is big, and therefore, the height of the head 8b of outside thread member 8 is done height and it is crimped on the shoulder 3c.
When the height of the inner face shoulder 3c of elongated slot 3 becomes higher, when head 8b that makes outside thread member 8 and shoulder 3c crimping, though then the required screwing length of the internal thread 9a of the outside thread 8a of outside thread member 8 and nut 9 becomes not enough, but in this occasion, as shown in figure 27, be fixed on above the teat 2d of sensor housing 2 by the nut 9 that thickness is thicker than Figure 24～Figure 26 occasion, just can tackle.Under the situation of Figure 27, shoulder 3c tilts.
In addition, as shown in figure 28, nut 9 is constant, and uses the bigger outside thread member 8 of head 8b size also can tackle.The outside thread member 8 that uses head 8b to vary in size comes the difference corresponding to elongated slot 3, also applicable to the 1st embodiment's who is embedded with barrel nuts 7 occasion.
As mentioned above, though it is trapezoidal that the head 8b of outside thread member 8 makes circular cone, but be applicable to various elongated slots 3, adaptability is higher, but as shown in figure 29, elongated slot 3 is made of the inner 3d of groove that the opening portion 3a and the cross section of rectangular cross-section is C shape, and when being the shoulder 3c of a circular arc part in the upper end part, both sides of the inner 3d of this groove, the head 8b of outside thread member 8 is also circular.In addition, as shown in figure 30, the shoulder 3c of elongated slot 3 is when the center of the inner 3b of groove is seen as level, and head 8b cross section also can be rectangle.In addition, also can make cross bath and replace in-line groove 8c.
