Abstract

PURPOSE:To prevent cut accident of spiral spring in such a way that the outermost peripheral part of a spiral spring whose inner end is fixed is brought into resilient contact with the inner circumference of the spiral spring casing by means of impetus force in the outer peripheral direction of an auxiliary spring, length of the auxiliary spring is specified, and said resilient contact is made reliable. CONSTITUTION:In case where it is applied for taking up the power cord of a vacuum cleaner, when a spiral spring device 48 has the power cord pulled out of a cord reel (unshown in the figure), a spiral spring 51 is taken up by means that a spiral spring casing 49 is turned through an output shaft 68, clutch pawls 67, 41, and toothed wheels 38, 42 by revolution of the cord reel. Then, the outermost peripheral part 51' of the spiral spring 51 whose inner end is fixed at its central boss 5 is prevented from convolving by means of action of an auxiliary spring 72, and it is brought into resilient contact with the inner circumference of the spiral spring casing 49. Here, the auxiliary spring 72 has its length determined to be a little longer than the inner circumference of the spiral spring casing 49, so that resilient contact of the outermost peripheral part 51' of the spiral spring with the inner circumference of the casing 49 can be made reliable.
