Abstract
A storage unit includes a wound body made of wound linear material and a storage body that stores the wound body. The wound body includes a first spiral part in which the wound linear material is spirally wound in a first winding direction such that a distance between the wound linear material of the first spiral part and a center of the wound body gradually decreases, a first inversion part, disposed inside the first spiral part, that inverts a winding direction of the wound linear material from the first winding direction to a second winding direction opposite to the first winding direction, and a second spiral part, disposed outside the first inversion part, in which the wound linear material is spirally wound in the second winding direction such that a distance between the wound linear material of the second spiral part and the center gradually increases.
