る。Among the above-mentioned known examples, the structure in which an engaging member that engages with the moving-side rotating frame and the fixed-side frame on the periphery of the rotation supporting mechanism so as to mesh with each other is provided. Since it is close to the rotation center, there is a problem that the load cannot be sufficiently supported. That is, the size of the rotation support mechanism is always smaller than the size of the moving-side rotation frame, and therefore, the movement-side rotation frame always has a cantilever portion that is not directly supported by the rotation support mechanism. There is a problem of becoming weak. Similarly, in a configuration in which the lower support member protruding upward is provided on the fixed side frame partially below the rotation support mechanism, the load applied to the portion distant from the rotation center is not sufficiently supported because it is close to the rotation center. There is a problem that. Similarly, in a configuration in which a support member protruding downward by a hard synthetic resin is provided at a predetermined position of the movable-side rotating frame, there is a gap between the lower end of the support member and the upper surface of the fixed-side frame. Although the load can be supported when the support member abuts due to the deformation of the frame, another sound is generated when the moving-side rotating frame vibrates up and down, and a contact sound (contact sound) between the lower end of the support member and the upper surface of the fixed-side frame is generated. Also arises. In view of this, the configuration is designed to be strong against loads, and the occurrence of abnormal noise is eliminated or suppressed.

く、荷重を支持でき、合理的な構成となる。Therefore, when the lower surface of the upper movable support member 31 rides on the upper surface of the lower support member 32, a single shaft member is provided between the fixed frame 1 and the movable rotary frame 2 in the same manner. Support the load. In particular, the fixed-side horizontal body 9 of the fixed-side frame 1, the movable-side horizontal body 13 of the movable-side rotating frame 2, and the rotation support mechanism 5 part form mutual strength members in a box shape in a side view. Support the load. Further, since the upper movable support member 31 and the lower support member 32 are provided on the movable rotary frame 2 and the fixed frame 1, respectively, the upper movable support member 31 and the lower support member 32 do not affect the rotation of the movable rotary frame 2 and are not affected by the rotation mechanism and the rotation. The load can be supported without affecting, and a rational configuration can be achieved.

であるから、フレーム強度を向上させる。According to the present invention, the center part of the movable side rotating frame 2 is attached to the center part of the fixed side frame 1 fixed or movably provided on a fixed part such as a vehicle body or the like by the rotation supporting mechanism 5 so as to be rotatable only. The moving-side rotating frame 2 is provided between the moving-side rotating frame 2 other than the support mechanism 5 and the fixed-side frame 1.
Is a rotating sheet provided with a guide and load supporting member 21 for guiding the rotation of the rotating frame 2 and supporting the load for lifting the moving-side rotating frame 2 upward. Support the load at the part. According to the present invention, the guide / load support member 21 has an arcuate shape concentric with the rotation center of the movable side rotating frame 2 in plan view, and has a U-shaped cross section and has an engagement portion 22 and an engagement portion 23, respectively. The U-shaped engaging portion 22 and the U-shaped engaging portion 23 are formed by a side guide member 24 and a fixed-side guide member 25, and the U-shaped engaging portion 23 is a rotating sheet configured to be engaged upward and downward with each other. Because of this, it is possible to guide the rotation and support the load with a simple configuration. According to the present invention, the center of a movable side rotating frame 2 is attached to the center of a fixed side frame 1 fixed or movably provided on a fixed portion such as a vehicle body by a rotation supporting mechanism 5 so as to freely rotate only. The moving side horizontal frame 1 of the moving side rotating frame 2
3, a frame mounting shaft 30 for mounting a frame of a sheet that vertically penetrates the moving body 3 is provided. The frame mounting shaft 30 that protrudes downward from the moving side horizontal body 13 is provided with an upper moving supporting member 31 that protrudes downward. The lower supporting member 32 is provided on the fixed frame 1 below the upper side, and the upper moving supporting member 31 and the lower supporting member 32 are formed of a hard synthetic resin, and the lower surface of the upper moving supporting member 31 and the lower supporting member 32 are formed. Since the rotating sheet is set so that the upper surface of the rotating sheet overlaps with the upper surface of the rotating sheet, it can be supported without interfering with rotation and without generating abnormal noise. According to the present invention, the edge of the moving-side rotating frame 2 with respect to the rotation supporting mechanism 5 and the moving-side annular upright of the moving-side rotating frame 2 are provided at a predetermined distance below the moving-side horizontal main body 13 of the moving-side rotating frame 2. Since the rotating seat is provided with the reinforcing member 20 fixed to the wall 12, the frame strength is improved.
