装置。 A tapered guide surface that slopes in the stroke direction of the actuating rod is formed on the back side of the piston in the wheel cylinder, and a roller is provided on the actuating rod that comes into contact with the guide surface, so that the actuating rod pulls together with the clevis when the brake is operated. In a wheel park brake device configured to actuate a park brake by pushing a piston against a roller when the piston is released, a bellows whose lower part is extendable and retractable in the stroke direction of the actuating rod is provided between the wheel cylinder and the actuating rod or clevis. A wheel park brake device characterized by being covered in a completely sealed state by a boot whose upper part is formed into a bag-like air pocket without creases.
