However, the probe 20 of this embodiment can be manufactured without the need for insert molding as described below. That is, the base components 35 and 36 of the probe 20
Is manufactured by an injection molding process separately from the terminal 22, and the terminal 2
2 and transported to the assembly site. Therefore, as shown in FIG. 4, the terminal 22 is accommodated in the accommodating portion 37 of the first base member 35, and the two base members 35 and 36 are joined together with their mounting surfaces facing each other. Then, the positioning projections 40 enter the positioning holes 41, and the two base components 35 and 36 are positioned relative to each other, and assembled without shifting (see FIG. 5). At this time, the leading end of the positioning projection 40 is deformed by the guide of the tapered surface 42 (see FIG. 7) provided in the positioning hole 41 so as to narrow the slit 40A. The peripheral surfaces adhere to each other. Thereby, both base component bodies 35 and 36 are provided.
The two will not rattle. In addition, the friction between the positioning projection 40 and the positioning hole 41 keeps the base components 35 and 36 in the temporarily locked state while being connected to each other. And
Carrier 2 of terminal 22 that protrudes forward from base 21
3 (see FIG. 5), and the front portion 31 of the base 21 is
0, and the assembly of the probe 20 is completed (see FIG. 6). In this state, the probe 20 is transported to another assembling factory and assembled into the brake device.
Here, since the probe 20 is held by the cylindrical body 50 so that the two base components 35 and 36 are in a joined state, even if the probe 20 is subjected to vibration or the like during the transportation, the two base components 35 and 36 are not connected.
36 does not decompose.

Now, the brake pad 14 is attached to the rotor 10
(See Fig. 1)
The cylinder 50 hits the rotor 10 before the base 21 to generate a sliding contact sound, thereby notifying that the brake pad 14 is approaching the wear limit. Therefore, if the brake pad is replaced at this time, the wire can be reused without replacing the probe 20 because the wire is not cut. Even if the sliding noise is not noticed, when the wear of the brake pad 14 further progresses and reaches the wear limit, the tip of the base 21 is worn down and the two leg pieces 24, 2 of the terminal 22 are worn.
4 is cut off, and the two electric wires D, D become non-conductive, so that the fact can be reliably notified.

As described above, according to the probe 20 of the present embodiment, the terminal 22 can be assembled inside the base 21 by a simple operation of joining the base components 35 and 36 to each other. The probe 20 can be manufactured inexpensively with less time and effort as compared to the conventional one. In addition, before the terminals of the probe 20 are disconnected, a warning can be given in advance by the sound of sliding contact between the cylinder 50 and the rotor 10, so if the brake pad is replaced at that time, the terminals 22 will not be disconnected. And the probe 20
Can be reused.
