A sliding member 220 slidably attached to the shaft portion 120, and a rotating portion main body 210 holding the sliding member 200 movably in the axial direction and having the shaft portion 120 inserted therein. It consists of A spring as the elastic means 300 is provided on one surface of the sliding member 220,
It abuts on one surface of the rotating portion main body 210 and elastically urges them in a direction of separating them. The other side of the sliding member 220 that abuts on the spring 300 abuts on the rotating roller 125 of the fixed portion 100, and the abutting surface 221 with the rotating roller is a door (rotating portion 200). ) Is formed as a tapered surface on which the sliding member 220 moves in the direction in which the spring 300 is contracted.

Therefore, when the door is rotated (for example, the door is pushed by hand), the rotating roller 125 rotates on the taper surface and the sliding member 220 moves the elastic member 300 toward the rotating portion main body 210. If the sliding force is slid against the elastic force and the door is rotated as described above and then the rotating force is eliminated (for example, when the hand is released from the door), the elastic force of the elastic member 300 causes the elastic member 300 to move. The door is automatically closed by the elastic means 300 by the sliding member 220 returning to a predetermined position (origin position) while the rotating roller 125 rotates on the tapered surface.

[0005]

However, in the above-mentioned conventional double door mounting member, the structure such as the mounting structure of the rotating roller 125 is complicated, and therefore the manufacturing cost thereof is high. There is.

In the door mounting member having such a configuration, when the rotating portion rotates when the doors are joined together (for example, by pushing the door by hand), the contact portion and the protruding surface of the mounting shaft portion are separated from each other. By sliding on the tapered surface, the sliding member slides against the elastic force of the elastic means. Then, when the force for rotating the door is eliminated in this state (for example, when the door is released), the sliding member slides due to the elastic force of the elastic means and returns to the original position. In this way, the tapered surface is used, the conventional rotary roller is not required, and the structure is simplified, so that the manufacturing cost can be reduced.
