PROBLEM TO BE SOLVED: To provide a push lock device for double sliding doors, which can constrain the two front and rear doors to each other in a lateral direction and a thickness direction. SOLUTION: According to the push lock device, a fixed case 3 is fixed to a front surface of a front door 1 at a vertically intermediate location, and a slender lock plate 5 is connected to a rear end of a lock cylinder 4. When the lock cylinder 4 is squeezed into the fixed case 3 against protrudingly energizing force of a spring 8, the lock plate 5 passes through a lock hole 6 of the rear door 2, and by rotating the lock cylinder 4 by a key 7 inserted into the same, long-side edges 5a, 5b of the lock plate 5 are engaged with hole rim rear surfaces 6a, 6b of a short side of the lock hole 6. Then, the lock cylinder 4 is locked to the fixed case 3, and the key 7 is pulled out of the lock cylinder 4.
