A latch device includes a case, a rod juts out from inside the case so as to adopt an advanced position, a rod biasing member biases the rod in a jutting out direction pushing the rod out from inside the case, a lock mechanism that includes a slide cam that moves together with the rod in the jutting out direction and a rotation cam that is relatively rotatable with respect to the slide cam about an axis of the rod, with the lock mechanism locking the rod in a retracted position in the case due to the rotation cam engaging with the slide cam and rotating due to the rod being pressed in, a guide mechanism for rotating the rod about the axial direction thereof when the rod is advancing or retracting, and an engagement portion that engages with an engaged portion when the rod has been locked. |

1. A latch device, comprising:
a tube shaped case that is fixed at a side of a second member that faces a first member; a rod that is retained inside the case so as to be capable of sliding, and that juts out from inside the case to adopt an advanced position pushing out the first member; a rod biasing member that is positioned between the case and the rod, and that is compressed under elastic deformation inside the case, so as to bias the rod in a jutting out direction pushing the rod out from inside the case; a lock mechanism including:
a slide cam that moves together with the rod in the jutting out direction, anda rotation cam that is provided at a rear side of the slide cam in the jutting out direction and that is capable of relative rotation with respect to the slide cam about an axis of the rod,with the lock mechanism positioned between the case and the rod, and locking the rod in a retracted position in the case due to the rotation cam engaging with the slide cam and rotating due to the rod being pressed in against a biasing force of the rod biasing member; a guide mechanism that is provided between the rod and the case, and is for rotating the rod about an axial direction of the rod when the rod is advancing or retracting; and an engagement portion that is provided at the rod, that is capable of disengaging from an engaged portion of the first member due to the rod rotating about the axial direction thereof, and that engages with the engaged portion when the rod has been locked. |
