In a vehicle park lock mechanism having a rotatable lock arm (5) for locking a gear (3) which is fixedly mounted on a transmission shaft (2), a pawl device integral with the lock arm is comprised of first and second locking pawls (6F, 6R) which are operable to engage the gear so as to prevent forward and backward directional rotations of the gear. The first and second pawls are arranged such that they may project into one and another toothe spaces (3b) of the gear which are spaced circumferentially of the gear with at least one tooth space therebetween. Gear having a relatively large pressure angle such as a transmission gear may satisfactorily be used as the gear for the lock mechanism. |
