ヤスタ内蔵型ホイールシリンダ。[Claims for Utility Model Registration] (1) A wheel cylinder body attached to a bucking plate, which is slidably and rotatably fitted into the wheel cylinder body, and whose outward flange portion abuts the wheel cylinder body. A piston whose return position is regulated by the piston, an adjuster screw which is screwed onto the piston with an irreversible screw and non-rotatably engaged with the brake shoe, and an adjuster screw which is built into the wheel cylinder body and has a shoe clearance. A wheel cylinder with a built-in auto-adjuster, comprising a rotary drive mechanism that rotates the piston so as to screw out the adjuster screw when braking in a state beyond the normal shoe clearance, the wheel cylinder having a built-in auto-adjuster. The present invention is characterized in that a boot is provided which is attached to the wheel cylinder main body and the adjuster screw so as to cover the tooth portion formed on the direction flange portion, and has a cut end formed at a portion facing the bucking plate. Wheel cylinder with built-in auto adjuster. (2) The auto-adjuster built-in wheel cylinder according to claim 1, wherein the cut is normally closed by elastic deformation of the boot.
