<P>PROBLEM TO BE SOLVED: To control the momentum of a door when it is opened and closed, and to inhibit the door from being easily opened and closed with an excessively light force, in a supporting device of the door rotatably supporting the door by a pin means. Ž<P>SOLUTION: In the supporting device of the door comprising an upper-part door supporting device and a lower-part door supporting device respectively supporting, by a pin means, an upper part and a lower part of a lateral side of the door arranged in an opening part formed by a door frame and a floor, a screw 98 is threadingly fitted to a screw hole 97 penetrating from a side face of a block 88 of a lower-part door side member 37 of the lower-part door supporting device 35 to a pin fitting hole 90a. By tightening the screw, a front end of the screw is brought into contact with a side face of a lower pin 42 inserted in the pin fitting hole, so that resistance may be applied to the rotation of the door. The upper-part door supporting device may also adopt the similar structure. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
