PROBLEM TO BE SOLVED: To provide a lock device for an indoor-side sliding door using a sliding door lock, which has high operational reliability and which can be downsized.;SOLUTION: The lock device is housed in the indoor-side sliding door 4 by arranging a locking-operation plate 11, a sickle-shaped locking member 5 and a detection member 13 of an outdoor-side sliding door 3 in a lock case 8. The plate 11 is vertically driven by control levers 7 and 7' which protrudes from/recedes into the sliding door 3; the locking member 5 protrudes from/recedes into the engage-in hole 6 of the sliding door 3, so that the sliding door 3 can be locked/unlocked; and the detection member 13 is urged to the outdoor side by a compression spring 12, and inhibits the shift of the plate 11 in a locking direction only in the terminal-end position of a pop-up side stroke. The detection member 13 with a diameter large enough to enable the insertion of a screwdriver 14 is formed in such a hollow-cylinder shape as to have a hollow part 13a facing a positioning hole 15 provided in the sliding hole 3 in a position in which the locking member 5 faces the engage-in hole 6.;COPYRIGHT: (C)2007,JPO&INPIT
