Claims

[Scope of utility model registration request]

A cylinder body having a cylinder hole formed therein, a piston that is slidably inserted into the cylinder hole and defines a pressure chamber, and a piston that is arranged between the piston and the brake shoe and screwed together so that the length can be adjusted. an annular dish-shaped ratchet foil fixed to an end of one of the screw members of the adjusting mechanism; and a claw portion that engages with the ratchet foil. In the wheel cylinder with an adjustment device, the ratchet wheel and at least one of the pair of threaded members are opposed to each other in cooperation with each other to prevent the ratchet from rotating in the direction of shortening the ratchet. A wheel cylinder with an adjustment device that forms a passage connecting the brake shoe side of the ratchet wheel and the cylinder body side.
