置。In a power steering device that controls fluid pressure acting on a fluid pressure cylinder through relative displacement of a pair of valve members as a steering shaft rotates, a valve hole is formed in the one valve member, and a valve hole is formed in the valve member. The vibration damping plunger is slidably fitted into the damping plunger and houses a spring that presses the vibration damping plunger toward the other member, and the valve hole receives the fluid pressure acting on the fluid cylinder. A power steering device characterized in that a so-called restriction portion is provided in the introduction path to restrict the outflow of the pressure fluid from the valve hole.
