いる。b. Prior Art Conventionally, in a proportioning valve, a braking hydraulic pressure control device of a type in which a tension spring is installed between the load detection lever and the axle has already been used. To explain this based on Figures 1 and 2, 1 is the valve body of the proportioning valve that is fixed to the bracket on the vehicle body using screw holes 2 and 3, 4 is the input hole, and 5 is the output hole. The input hole 4 communicates with a master cylinder 7 and a front wheel cylinder 8 via a conduit 6, and the output hole 5 communicates with a rear wheel cylinder 10 via a conduit 9.

止される（第５図の特性線のＡ点）。 The brake fluid pressure guided from the master cylinder 7 to the input hole 4 via the conduit 6 is applied to the plunger 1.
1, the valve body 15a pushed up by the rod 14 of the plug 13, and the valve seat 15b attached to the plunger 11 are guided to the output hole 5, and further the conduit 9 to the rear wheel cylinder 10. Therefore, the input hydraulic pressure and the output hydraulic pressure are the same pressure at the initial stage of braking. By the way, the plunger 11 has a small diameter portion 11a and a medium diameter portion 1.
1b, and the pressure receiving area of the output liquid that acts to push up the plunger 11 is larger than the pressure receiving area of the input liquid that acts to push down the plunger 11. Therefore, at the initial stage of braking, the hydraulic pressure acts equally on the small diameter portion 11a and the medium diameter portion 11b via the input/output holes 4 and 5.
The plunger 11 obtains an upward biasing force due to the difference in these pressure receiving areas. However, at the initial stage of braking, the spring means (tension spring 16, elastic body 20)
Since the urging force pushing down the plunger 11 is greater, the valve body 15a is maintained in the open state. As the braking fluid pressure increases, the force pushing up the plunger 11 increases, and when this upward force overcomes the downward force exerted by the spring means, the plunger 11 moves upward and opens the valve. The body 15a is closed, and the increase in hydraulic pressure on the output hole 5 side is stopped (point A on the characteristic line in FIG. 5).

Ａ−Ｂ）。 Furthermore, when the input hydraulic pressure of the input hole 4 increases,
Since the output hydraulic pressure does not increase (the valve body 15a is closed), the differential pressure between the input hydraulic pressure and the output hydraulic pressure increases. Then, when the input hydraulic pressure reaches a certain ratio to the output hydraulic pressure, the plunger 11 is moved downward,
Valve body 15a is opened. Thereafter, as the input hydraulic pressure increases, the valve body 15a is opened and closed continuously, and as a result, the output hydraulic pressure increases while being reduced at a constant ratio to the input hydraulic pressure (characteristics shown in Fig. 5). line A-B).

性という。 This depressurizing action starting pressure is naturally transmitted from the tension spring 16 to the connecting portion 17, the load detection lever 18, and the stem 1.
9. It depends on the urging force applied to the plunger via the elastic body 20 and the abutting member 21. For example, when the load increases, the distance between the vehicle body and the axle decreases, and the tension spring 16 is stretched. Therefore, the force that urges the plunger 11 downward increases, and the depressurization start pressure of the characteristic line in FIG. 5 increases.
Move in direction A′. This decompression start pressure is smaller as the upward tensile force of the tension spring 16 in the diagram, that is, when the distance between the vehicle body and the axle is unloaded (no load is loaded) increases, so the upward force on the plunger 11 is smaller. The biasing force is the smallest when the load is empty. The ideal pressure reduction characteristics under such conditions are called unloaded characteristics.

Problems to be Solved by the Invention As described above, conventionally, as one of the specific means for applying a force to the plunger according to the live load, a load detection lever is linked to the plunger, and the load detection lever and the axle are connected. A device in which a tension spring is installed between the two is known, but this device has the required hydraulic characteristics,
In particular, in order to obtain the unloaded characteristics (OAB line in Figure 5), it is necessary to accurately set the effective length of the tension spring when set. However, with conventional devices, when fixing the proportioning valve to the vehicle body, first, the load detection lever is positioned at the operating limit position (the plunger is pushed in), and then the spring mounting part of the load detection lever and the axle are connected. Fix the valve body of the proportioning valve to the vehicle body so that there is a predetermined distance between it and the spring attachment part on the side.
Then, hooks at both ends of the tension spring were attached to these attachment parts. However, according to this method, it is necessary to measure between the spring mounting part of the load detection lever and the spring mounting part on the axle side using a gauge, etc., which tends to result in inaccurate measured values, and after that, the measurement values are likely to be inaccurate. Since the tension spring is attached to the mounting part, installation errors are likely to occur. Therefore, there was a problem in that skill was required to obtain the required hydraulic characteristics.
