Claims

[Scope of utility model registration request]

In a parking brake device having an actuator that reduces the operating force of the operating lever of the parking brake and can operate the parking brake by a switch operation or automatically, the operating lever detecting means for detecting the operation of the operating lever is provided. The parking brake device is characterized in that when an operation of the operation lever is detected in a state in which the actuator is actuated by an operation by the operator, the operation by the operation switch is released.
