Claims

[Scope of utility model registration request]

a cylinder body having first and second inflow ports that communicate with the first and second liquid chambers of a master cylinder, respectively, and first and second outflow ports that communicate with the first and second wheel cylinders, respectively; The liquid chamber is slidably inserted into the first space of the body, and partitions a first liquid chamber communicating with the first inflow port and a second liquid chamber communicating with the first outflow port, and acts on the difference in pressure receiving area between them. A first spool that opens and closes a first valve provided between a first liquid chamber and a second liquid chamber is slidably inserted into a second space of the cylinder body by the hydraulic pressure, and is inserted into a second inflow. The third liquid chamber communicating with the port and the fourth liquid chamber communicating with the second outflow port are partitioned, and the liquid pressure acting on the difference in pressure receiving area between the third liquid chamber and the fourth liquid chamber is divided. A parallel type comprising a second spool that opens and closes a second valve provided in the second valve, and a spring that biases one end of the first and second spools arranged in parallel so as to release the first and second valves. In the proportioning valve, the spring seat is formed of a single plate-like body having a pair of through holes, and the through holes are respectively engaged with protrusions on one end side of the first and second spools, and at least A bolt member in which one protrusion and the through hole are loosely inserted with a predetermined gap, the load of the spring is applied to the spring seat, and at least one protrusion is screwed onto the first or second spool. 1. A parallel proportioning valve, characterized in that the spring seat is formed of a spool, and the tilting movement of a spring seat is regulated between the side surface of one end of the spool and the head of the bolt member.
