A latch device (14) includes a latch bolt (30) movable between a latching position and an unlatching position. A sleeve (775) is mounted to an outer side (13A) of a door (11) and operatively connected to an outer operational device (12). A clutch (575) is mounted to and jointly movable with the sleeve (775). An unlatching member (711) is operably connected to the latch bolt (30) and releasably engaged with the clutch (575). When the unlatching member (711) engages with the clutch (575), operation of a handle (502) of the outer operational device (12) retracts the latch bolt (30). When the unlatching member (711) disengages from the clutch (575), the latch bolt (30) remains in the latching position if the handle (502) is rotated.
