  • Publication number: 20230392418
    Abstract: In a vehicle lock apparatus (1), an open/close mechanism (3) includes: a drive source (M1); an actuation lever (30) supported coaxial with a fork (10) to be swingable in first and second directions (R1, R2) independently of the fork; and a drive train (50) that swings the actuation lever: in first direction (R1) by transmitting a first driving force from the drive source to the actuation lever, and in second direction (R2) by transmitting a second driving force, opposite to the first driving force, from the drive source to the actuation lever. The actuation lever includes: a first operation portion (39) that can swing in first direction (R1) to abut on the fork and cause the fork to swing to a latched position; and a second operation portion (49) can swing in second direction (R2) to abut on a pawl (20) and displace the pawl to a nonblocking position.
