Abstract
A door latch device has a hook leverfor switching a lock leverresiding at a locked position L to an unlocked position U when an inner open leveris rotated, and a pressing springfor coupling the lock leverand an open link. When the lock leveris switched to the unlocked position U from the locked position L while an outer open leveris in an actuated position Y, although the open linkis not displaced to an engaging position, the pressing springis compressed. The open linkis pushed out to the engaging position by elasticity of the pressing springwhen the outer open leveris returned to a stand-by position X while the pressing springis compressed.
