整装置。 A piston is slidably fitted into the cylinder to define a liquid chamber between the cylinder and an integral opposing member;
An adjusting bolt having a multi-start thread is screwed onto the piston, a cone piston is elastically connected to the head of the bolt, and the cone piston is made non-rotatable with respect to the bolt. It forms a clutch surface that frictionally engages with the opposing member, and also forms a hydraulic pressure receiving part that receives the hydraulic pressure of the liquid chamber, and when the axial force acting on the hydraulic pressure receiving part reaches a predetermined value, An automatic brake adjustment device characterized in that the cone piston does not move.
