1. A door latch device comprising:
- an engagement unit which has a box-like body housing an engagement mechanism engaging with a striker of a vehicle body and a cover member covering an opening of the body, and the engagement unit being fixed to an inner side of an inner panel of a door;
a casing connected to the engagement unit; and
a childproof locking mechanism housed in the casing, which is shifted between a childproof unlock state and a childproof lock state,wherein in the childproof unlock state, an engagement between the engagement mechanism and the striker is released by transmitting a release operation of an inside lever to the engagement mechanism depending on a door opening operation of an inside handle provided on a vehicle interior side of the door, andwherein in the childproof lock state, the engagement between the engagement mechanism and the striker is not released by making said transmission impossible;
wherein the childproof locking mechanism comprises a childproof lever pivotally supported on the casing by a support shaft extending in a transverse direction of a vehicle to shift between the childproof unlock state and the childproof lock state, andwherein a manual operation part is formed at an end portion of the childproof lever extending in a longitudinal direction of a vehicle perpendicular to the support shaft such that the manual operation part passes through the cover member and projects from this member.
