も狭くした円筒ばね。 A slit group consisting of N circumferential slits formed point-symmetrically with respect to the axis of the thin-walled hollow cylinder is provided on the outer peripheral surface of the thin-walled hollow cylinder, and the slit group is arranged in the axial direction of the thin-walled hollow cylinder. In a cylindrical spring in which a plurality of slits in adjacent slit groups are deviated from each other by 180/N degrees in the circumferential direction of the thin-walled hollow cylindrical body, the slits in the slits in the adjacent slit groups are offset from each other by 180/N degrees in the circumferential direction of the thin-walled hollow cylindrical body. A cylindrical spring in which the width of each slit in the slit group located on the outside is narrower than the width of the slit in the other slit groups.
