A latch device for a vehicle includes an engageable member having an engageable notch engageable with a striker, a shaft member by which the engageable member is rotatably supported, a first body including a first support portion by which one end of the shaft member is supported, and a second body including a coupling portion coupled to the first body, and a second support portion by which another end of the shaft member is supported. The engageable member is rotatable about the shaft member between a first position in which engagement with the striker is achievable and a second position in which disengagement from the striker is permitted. With the first body, an entrance of the engageable notch through which the striker comes in the engageable notch in a state where the engageable member is in the first position is covered from one side in an axial direction of the shaft member. With the second body, the engageable notch in the state where the engageable member is in the first position is not covered, but left uncovered in entirety, from another side in the axial direction of the shaft member.
