Abstract: A vehicular lock device comprises a main latch engageable with a main striker and rotatable, a main ratchet engageable with the main latch in order to keep an engagement relation between the main latch and the main striker, a subsidiary latch adapted to engage with a subsidiary striker and rotate, a subsidiary ratchet adapted to engage with the subsidiary latch in order to sustain an engagement relation of the subsidiary latch with the subsidiary striker, and a rotation lever engageable with the main latch and rotatable correspondingly to rotation of the main latch. Both the latches, both the ratchets, and the rotation lever, respectively are journalled rotatably to the same body of the lock device. When the latch engages with the main striker and the former rotates, the rotation lever rotates so as to make the subsidiary ratchet released from the subsidiary latch.
