している。The retaining member 42 is made of a synthetic resin material and has an annular projection 42a protruding toward the valve chamber 33. The tubular portion 43b of the retainer 43 has an annular projection 42a.
It is locked to a. Therefore, in the present embodiment, a plurality of (three in the present embodiment) protrusions 42b as clearly shown in FIGS. 3 and 4 are formed on the outer periphery of the annular protrusion 42a, and the plurality of protrusions are formed. 42b holds the inner circumference of the tubular portion 43b of the retainer 43 to hold the retainer 43 securely. In addition, the tubular portion 43 of the retainer 43
By forming the inner peripheral portion 43c of the distal end of the stopper b on the side of the retaining member 42 into a curved shape that spreads radially outward, the retaining member 42 (precisely, the protrusion 42b) is damaged during assembly, and The function of the hydraulic control valve P is prevented from being adversely affected. On the other hand, the protrusion 42 on the retaining member 42 side
By forming b in a taper shape that is radially inwardly inclined toward the tip of the protrusion 42a, it is possible to facilitate the assembling and to cope with the thermal expansion and the thermal contraction of the retaining member 42. The inner peripheral side of the annular protrusion 42a supports one end of a valve spring 41 that urges the valve body 38 toward the valve seat 37, and the annular protrusion 42a also supports the valve body 38 when the brake is loosened. The valve spring 41 is prevented from buckling by restricting its movement toward the retaining member 42 side. At this time, the notch 42c provided in a part of the annular protrusion 42a prevents the protrusion 42a and the valve body 38 from coming into close contact with each other and blocking the gap between the inlet 31 side and the outlet 32 side.

る。The on-off valve 50 will be described below.
A cylinder member 51, which is fluid-tightly fitted into the inner hole 44 formed in, is provided with a plunger 52 that is movable in the axial direction in response to the excitation of the solenoid portion 55, and at the same time, the tip of the plunger 52 is A valve seat forming member 53, on which the valve portion 52a can be seated / separated, is press-fitted. A spring member 54 is provided between the plunger 52 and the valve seat forming member 53, and when the solenoid portion 55 is demagnetized, the valve portion 5
2a is separated from the valve seat. That is, the on-off valve 50
Is configured as a normally open electromagnetic switching valve. Inner hole 44
Is connected to the valve chamber 33 of the fluid pressure control valve P via the communication passage 61, and is connected to the control chamber 46 and the communication passage 4 which the pressure receiving portion 35A formed at the outlet 32 side end of the stepped piston 35 faces.
It is connected via 5. Therefore, the master cylinder pressure is supplied to the control chamber 46 by opening the opening / closing valve 50.

ックを防止する。That is, when the braking force distribution control device fails, a control unit (not shown) issues a valve opening command to the on-off valve (stop power supply) so that the master cylinder pressure is applied to the control chamber 46. The sum of the acting force acting on the pressure receiving portion 35A of the stepped piston 35 and the acting force due to the pressure acting on the large diameter portion 35B is the acting force by the pressure acting on the small diameter portion C of the stepped piston 35 and the preload spring 39. When the sum of the urging force and the stepping piston 35 is exceeded, the stepped piston 35 is moved to the left in the figure and the valve body 38 is seated on the valve seat 37, thereby blocking the inlet 31 side and the outlet 32 side. Then, when the pressure on the inlet 31 side increases and the acting force that moves the stepped piston 35 to the right in the figure becomes larger, the inlet 31 side and the outlet 32 side are made to communicate again. By repeating these actions, the known brake fluid pressure reducing action is performed, and the early locking of the rear wheels due to the failure of the braking force distribution control device is prevented.

It does not vibrate even if it receives a pulse pressure generated in the valve chamber 33 when it is loaded or loosened, and therefore,
It is possible to prevent the generation of abnormal noise.
