A vehicle seat is provided. In the vehicle seat, a cutout 12 is formed in an upper edge of a seat back 5 at an end portion in a width direction of a vehicle. A lock member 8 is supported in the cutout 12 rotatably about a side axis. The lock member 8 has a hook portion 8a which is engageable with a lock striker 10 provided on a vehicle body and a handgrip 8c. By rotating the handgrip 8c forwardly, the hook portion (8a) is rotated forwardly in the vehicle as a result of the handgrip 8c being rotated forwardly in the vehicle, so that the hook portion can be disengaged from the lock striker 10 and that the seat back 5 can be rotated forwardly about a pivot provided at a lower end of the seat back 5.
