Abstract

In a parking brake system, a locking tooth of a ratchet plate includes a first area for contacting and retaining a locking claw of a ratchet pawl in an equilibrium state when a parking brake lever is pulled up; and a second area in which the locking claw remains in a state of halfway engagement of tooth tips when a pressing force of a release rod is released. When the locking claw comes into contact with a portion closer to a tip of the locking tooth beyond the first area, a line of force is maintained due to the pressing force of the release rod. The system is configured such that even if an occupant erroneously pulls up the parking brake lever while the release rod is pressed, it is possible to reliably prevent halfway engagement of tooth tips in a ratchet mechanism.
