As a variable resistance type pressure detection device, for example, a fourth
There is a structure as shown in the figure. This consists of a diaphragm 2 that receives pressure supplied from a pressure supply port 1 and converts the pressure change into vertical displacement, a rotating frame 3 that magnifies this displacement and converts it into rotational displacement, and is attached to this rotating frame 3. It has a movable contact 4, a wire-wound resistor 5 with which the movable contact 4 comes into sliding contact, and a frame 6 of the pressure detector.
A diaphragm 2 has a variable resistance substrate 7 fixed to the diaphragm 2 and fluctuates depending on the pressure supplied from the supply port 1.
This movement operates the movable contact 4, and the change in resistance is detected as a pressure value. The specific structure of the variable resistance substrate 7 is as shown in FIG. 5, in which a resistance wire 9 is wound around the resist base 8.
One terminal of this resistance wire 9 is connected to the resist base 8
The other terminal is connected by winding it around the terminal 10 that has been attached in advance to the resist base 8 and then soldering it. It was hot.

る。(Means for Solving the Problems) The present invention was devised by focusing on such conventional problems, and is based on a pressure sensor in which a resistance wire is wound around which a movable element slides in response to changes in pressure. In the variable resistance board, one end of a hollow rivet is inserted into a part of the board and fixed by caulking, the end of the resistance wire is wound around the other end of the rivet, and a sleeve is inserted into the other end of the rivet. The object of the present invention is to provide a variable resistance board that secures connection with a resistance wire by crimping the other end of the rivet and has excellent connection reliability.

抗線９の接続ができるものである。 8 is a resist base, and 9 is a resistance wire wound around the resist base 8, which are the same as those described in the conventional example. The resist base 8
A tubular rivet 12 as shown in FIG. 2 is passed through the hole. That is, this rivet 12 has a flange 12' near its upper end, and the flange 12' is attached to the resist base 8 from the upper surface side of the through hole drilled in the resist base 8 at the lower end 12'' side of the rivet 12. Insert until it joins to the top surface of 8.
Next, by tightening the lower end 12'' of the rivet 12 protruding from the lower surface of the resist base 8,
The rivet 12 is fixed to the resist base 8. Then, on the upper end 12 of the rivet 12,
After winding the end portion of the resistance wire 9, the upper end portion 12
The sleeve 13 is fitted into the sleeve 13, and then the upper end 1
By crimping 2, the end portion of the resistance wire 9 is connected between the flange portion 12' and the sleeve 13 with pressure. Note that the lead wire 15 is inserted into the hollow hole 14 of the rivet 12, and the lead wire 15 is inserted into the hollow hole 14 of the rivet 12.
By soldering the and rivets 12, the resistance wire 9 can be connected.

As described above, according to the present invention, the resistance wire 9 with poor solderability is integrally connected to the rivet 12 by the caulking action of the rivet 12.
This has the effect of increasing the reliability of the electrical connection between the resistance wire 9 and the rivet 12. Also, crimping is performed to fix the rivet 12 to the board 8, and the resistance wire 9 is connected to the rivet 12.
Since the crimping is performed separately to fix the resistance wires, it is possible to prevent the ends of the resistance wires from loosening due to thermal expansion, etc.
