Abstract:
[Problem] To provide a safety device for a sliding door with which finger pinching can be automatically prevented without manually operating a stopper, and which can be smoothly closed without a resistance that acts when closing the sliding door. [Solution] A safety device for a sliding door is provided with a guide frame 11 and a feed plate 12 that are mounted on the opening side and the sliding door side, respectively, so as to face each other.

In addition, when the feed plate 12 collides with the disk roller 14 at a force stronger than or equal to a prescribed value, the shaft 14b of the disk roller 14 is moved from inside the low-speed movement groove 38a to inside the lock groove 38b and the movement of the disk roller 14 in the left-right direction is locked.
