ABSTRACT:
A noise suppressing device in a lock device for a vehicle, including a body to be fixed to a door of the vehicle; a latch rotatably supported in the body and adapted to be rotated by engagement with a striker fixed to a vehicle body; a ratchet rotatably supported in the body and adapted to engage a full-latch stepped portion of the latch and thereby prevent reverse rotation of the latch; first and second spring members for biasing the ratchet to engage the same with the latch; and an open lever for releasing engagement of the ratchet with the full-latch stepped portion; wherein the first spring member normally biases the ratchet to engage the same with the latch, and the second spring member does not bias the ratchet under a full-latch condition where the ratchet is engaged with the full-latch stepped portion of the latch, while when the ratchet is rotated in a releasing direction, the second spring member biases the ratchet.
