Abstract

A servo regulator that causes a servo piston to move on the basis of working fluid pressure in two pressure chambers includes: a sleeve that is inserted into an insertion hole formed in a case and has a supply port capable of supplying a working fluid from a fluid pressure source to one of the pressure chambers; a spool valve disposed in the sleeve so as to be biased by a biasing member; and a solenoid that is attached to the case in order to drive the spool valve via a plunger. The sleeve includes a pressure receiving portion on which a fluid pressure of the working fluid from the fluid pressure source is exerted, and is pressed against an end surface of the solenoid by a biasing force acting on the pressure receiving portion.
