  • Patent number: 11554702
    Abstract: 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.
