PROBLEM TO BE SOLVED: To provide a connection structure of a constant load spring unit, capable of eliminating generation of noise such as a collision sound and a deformation sound, by improving the connection structure in the delivery end of a spring band body of the constant load spring unit.SOLUTION: A fixed member 1 and a moving member 2 are connected via a constant load spring unit 10. The constant load spring unit 10 comprises: a spool 22; and a metallic spring band body 23. The delivery end of the spring band body 23 is connected via a connection plate 31 to a connection base 30 fixed to the fixed member 1. The spool 22 is rotatably supported by the moving member 2. The base end of the connection plate 31 is connected to the connection base 30 by one first fastening body 44, and the projection end of the connection plate 31 is connected to the delivery end of the spring band body 23 by one second fastening body 45. The connection plate 31 is connected to the connection base 30 in a state of inclining at least the projection end side of the connection plate 31. Thus, initial swelling of the delivery end of the spring band body 23 is promoted by the connection plate 31, and the delivery end of the spring band body 23 is brought into close contact with the connection base 30. |
