Parking brake device

A first component (28), which is connected to a transmitting component (22) that transmits a brake operation by a driver, is arranged to travel, in response to the brake operation, in a direction in which the transmitting component (22) travels. A second component (32) has a pressure portion (32B) to press a brake piston (40), which actuates friction components of a brake mechanism (14), in a direction different from the direction in which the transmitting component (22) travels. The first component (28) has an inclined surface (28E). The second component (32) has a contact portion (32C), which comes into contact with the inclined surface (28E), and is arranged such that the pressure portion (32B) turns about a fulcrum (32A) upon the traveling of the first component (28).
