PROBLEM TO BE SOLVED: To provide a slide latch lock which has a clutch interposed between a connection shaft and a display plate, wherein the slide clutch lock is set up so as to transmit rotating force of the connection shaft to the display plate even if the clutch goes out of order. SOLUTION: According to the structure of the slide latch lock, a projection 42e is formed on an end face of a driven shaft 42 of the connection shaft, close to a display plate support body 20, and a dip 54 is formed in a rear surface of the display plate 50, followed by energizing the driven shaft 42 toward the display plate 50 by a spring 60. Thus, the projection 42e and the dip 54 are fitted to each other to constitute a claw clutch. Further, an auxiliary rotary mechanism is set up by forming a flange 42b with a lug 42c at an edge of the driven shaft 42, close to the display plate support body 20, and forming a protrusion 56 formed on the rear surface of the display plate 50, for receiving the lug 42c. Thus, even if the clutch does not perform engagement and goes out of order, the lug 42c engages with the protrusion 56, and therefore the display plate 50 is forcedly rotated in interlock with the connection shaft 40. Accordingly, a used state display section and an unused state display section of the display plate 50 is switchably displayed, and discrimination between a used state and an unused state of a room is facilitated.
