Claims

[Scope of utility model registration request]

In vehicles equipped with a mechanical center brake device that generates braking force by cam drive, the first switch detects input to the parking lever, the second switch detects when the driver leaves the seat, and the driver's door opens. a third switch that detects zero rotation of the wheel, a fourth switch that detects zero rotation of the wheel, a motor that operates in response to signals of the first switch being off and the second to fourth switches being on; An automatic parking brake comprising: a gear mechanism that drives a cam of the center brake device when activated.
