PARKING BRAKE DEVICE

WIPO Patent Application WO/2010/090155

A1

On the engaging tooth (17a) of a ratchet plate (17) of a parking brake device, there are a first region (S1) wherein the pawl (19c) of a ratchet pole (19) makes contact and is stopped in a balanced state when the parking break is loosened after being pulled up while a release rod is pushed, and a second region (S2) wherein the pawl is stopped in a half-engaged state near the tip of the tooth when the release rod pushing force is removed. Because the load line of force (F1) is thereby maintained by the release rod pressing force when the pawl (19c) makes contact closer to the tip of the engaging tooth (17a) than the first region (S1), the pawl (19c) sliding over the engaging tooth (17a) and becoming half-engaged near the tooth tip is prevented without becoming half-engaged near the tip of the tooth in the second region (S2). The occurrence of a half-engaged state near the tip of the tooth of the ratchet mechanism can be reliably prevented even when a rider mistakenly pulls up the parking break lever to the actuated position while pushing the release rod.
