[0002]
[Prior art]
In recent houses, it is common to have a door stopper that prevents the door from opening beyond a predetermined opening for crime prevention.
[0003]
Such a door stopper does not have any regulating force in the direction of closing the door, so that the door is closed arbitrarily in a natural state.
[0004]
However, in order to ventilate the room, there are cases where windows and doors are opened particularly in highly airtight condominiums, etc. In order to keep the doors open properly, the space between the doors and the floor surface may be maintained. At present, some kind of ingenuity has been made individually, such as sandwiching wedges and their substitutes. However, it is rare to make wedges, and weekly magazines are often used as substitutes.
[0005]
However, since it does not look good to hold a weekly magazine, etc., an open maintenance tool that maintains the door opening state at a position where the door opening degree is regulated while maintaining the function of the door stopper for crime prevention is proposed It was done.
