PROBLEM TO BE SOLVED: To provide a sure door nonslip device by simple adjustment at the time when the door is installed. SOLUTION: The door nonslip device has a supporting member 3 fixed onto the lower section of the door 2, a stopper member 4, which is installed to the member 3 so as to be able to be vertically moved between the uppermost place and the lowermost place projected to a section lower than the member 3 and in which a lower section is engaged with a rail 29, a spring 5 urging the member 4 in the direction that the member 4 is moved downwards by a force smaller than a force supporting the weight of the door 2 and a changeover member 6 mounted on the member 3 so as to be changed over at a place, where the removal of the door is inhibited, and a place, where the removal of the door is allowed, and be held at both places respectively. The vertical movement of the member 4 between both places is allowed when the member 6 is positioned at the place of the inhibition, and the downward movement of the member 4 from the uppermost place is inhibited when the member 6 is positioned at the allowable place.
