たホイールシリンダー。 A wheel cylinder equipped with an automatic gap adjustment mechanism that rotates when the piston protrudes beyond a predetermined extrusion length during braking, and the push bolt that is threadedly engaged with the piston protrudes excessively in accordance with the rotation angle to adjust the gap. , the piston 2 is provided with a circumferential groove portion 6 having a large diameter in the radial direction in the screw hole 5 which is screwed into the screw portion 7 of the push bolt 3, and a truncated conical head end portion 10 at the tip portion. A recessed groove 8 formed in connection with the head end 10, a press bolt 3 connected to the recessed groove 8 and provided with a threaded portion 7 on its outer peripheral surface, and an inner ring 11 and an outer ring 12 formed by bending a single wire. The inner ring 11 of the stop ring 4 is engaged with the concave groove 8 of the push bolt 3, and the outer ring 12 is connected to the piston 2. A wheel cylinder formed to engage the circumferential groove 6 to limit the protrusion of the push bolt 3 to prevent over-adjustment of the clearance.
