PROBLEM TO BE SOLVED: To attain a complete barrier-free state by manufacturing an automatic door and a sliding door, which have required grooves for a bracing, so as not to be shaken even when there is no groove so that the aged, little kids and the sick do not stumble. SOLUTION: In the automatic door and the sliding door, sash sheaves 1 are stacked at three stages on a bolt 3 fixed to a left section in the case of a sliding, and a guard 7 assembled in a lower stile 5 is engaged with sash-sheave frees 2 at multiple levels left and right.
