Insert into. Thereby, the support member 14 having the ornament 12 can be supported by the support shafts 18 inserted into the support holes 34 and 40.

  Thus, since the support shaft 18 can be inserted into the through holes 24 and 26 from the outside of the frame member 16 and the support member 14 can be attached to the frame member 16, the support shaft protruding from the support member is formed on the frame member. Compared with the conventional configuration of inserting into the support hole, assembly processing is facilitated.

  At this time, the insertion portion 18C of the support shaft 18 is provided with a contact portion 42 that contacts the inner wall surface of the support holes 34 and 40 located above the insertion portion 18C. It consists of For this reason, the support state becomes unstable by supporting the upper surfaces of the inner wall surfaces 34B, 40B of the support holes 34, 40 with the contact portions 42 formed by the corners of the support shaft 18. Thereby, even if the frame member 16 moves slightly, the support member 14 can be easily shaken around the support point.

  Further, the support member 14 is supported in a state in which the contact portion 42 is in contact with the inner wall surfaces 34B and 40B of the support holes 34 and 40 from below. For this reason, when the rotating rod of the supporting member is supported by the circular hole of the frame member and the supporting member swings, the rotating shaft rolls along the inner wall surface of the circular hole. Compared with the conventional technique, the swinging of the support member 14 with respect to the support shaft 18 can be facilitated. Thereby, the ornament 12 supported by the support member 14 can be easily swung.

  In addition, the inner diameters DR and DL of the support holes 34 and 40 into which the insertion portion 18C of the support shaft 18 is inserted are increased in the insertion direction S of the insertion portion 18C as shown in FIG. Each support hole 34, 40 is reduced in diameter toward the outside. As a result, sharp edges 34A and 40A are formed at the opening edge portions on the outer surface side of the respective support holes 34 and 40, and the ridge line portion forming the contact portion 42 of the insertion portion 18C is the edge 34A, Cross and abut against 40A. Thereby, since the contact part 42 of the insertion part 18C and the edges 34A and 40A of the support holes 34 and 40 make point contact, it is possible to provide a degree of freedom in the swinging direction of the support member 14 with respect to the frame member 16.

  And the length dimension LN of the diagonal shape of the rhombus shape which the insertion part 18C comprises is set longer than the internal diameter dimension DT of the minor axis direction of the elliptical shape which the corresponding support holes 34 and 40 comprise. Thereby, the rotation of the support member 14 supported by the support shaft 18 by 180 degrees can be prevented, and the reverse of the back surface of the decorative object 12 can be prevented.

  Further, the support positions of the support holes 34 and 40 supported by the contact portion 42 of the support shaft 18 are located above the center of gravity G of the support member 14 holding the decoration 12, and the center of gravity G of the support member 14. Can be lower than the support position. For this reason, it is possible to prevent the support member 14 holding the ornament 12 from turning over. Further, the support member 14 holding the decoration 12 can be easily swung as compared with the case where the center of gravity G of the support member 14 holding the decoration 12 and the support position are the same height.

  In the present embodiment, the case where the frame member 16 has an annular shape surrounding the support member 14 has been described. However, the shape is not limited to this shape, and any shape can be used as long as the support member 14 can be supported. It may be a simple shape.
