<P>PROBLEM TO BE SOLVED: To provide a band device which can be quickly wound on an object even if an entire length is long. <P>SOLUTION: The band device includes: a main plate spring 1 configured such that, after a band-shaped metal plate 1' is bent, in a widthwise cross section, with one face 1a facing the inside of the bend and subjected to tempering, the metal plate 1' is formed in a ring shape with the other face 1b of the metal plate 1' facing the inside of the ring, the main plate spring being held in a linear state by the widthwise bend and being restored from the linear state to the ring state when the bend is released; and a secondary plate spring 2 formed in a ring shape with one face 2a side of the band-shaped metal plate 2' facing the inside of the ring. The two plate springs are firmly fixed at a point between both ends of the two plate springs 1, 2, with the one face 1a of the linear main plate spring 1 superimposed on the one face 2a of the linear secondary plate spring 2 to face each other, and are bundled using metal bands 4 wound around the two plate springs 1, 2 and firmly fixed to the main plate spring 1 at points other than the firmly fixed point 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
