The present invention provides a wound body that can prevent the wound body from being attached in the opposite direction. A wound body used in a medicine packaging apparatus for packaging a medicine using a long sheet-like packaging material, the medicine packaging apparatus including a support shaft 32 for supporting the wound body, and the winding The rotating body includes a core body 61 that is cylindrical and is attached to the outer periphery of the support shaft 32. The core body 61 has a normal orientation from one end side and from the tip end side of the support shaft 32 to the support shaft 32. A groove portion 329 having a contacted portion is formed on the outer peripheral portion of the support shaft 32, and the wound body protrudes inward from the inner peripheral portion of the core body 61 and has an insertion portion 613 inserted into the groove portion. The insertion portion 613 is formed with a contact portion 6132 that contacts the contacted portion, and when the core body 61 is attached to the support shaft 32 from the other end side in an irregular direction, When the contact portion 6132 is in contact with the contacted portion, the core body 61 is supported by the support shaft 32. Against is blocked on the way to move to the regular mounting position. [Selection] Figure 5【課題】巻回体の逆方向への装着を防止できる巻回体を提供する。【解決手段】長尺シート状の包材を用いて薬剤を包装する薬剤包装装置に用いられる巻回体であって、前記薬剤包装装置は巻回体を支持する支持軸３２を備え、前記巻回体は、筒状で支持軸３２の外周に装着される芯本体６１を備え、芯本体６１は、正規の向きとして一端部側から、かつ、支持軸３２の先端部側から支持軸３２に装着され、支持軸３２の外周部には被当接部を有する溝部３２９が形成され、巻回体は、芯本体６１の内周部から内方に突出し、溝部に挿入される挿入部６１３を備え、挿入部６１３には、被当接部に当接する当接部６１３２が形成され、芯本体６１が非正規の向きとして他端部側から支持軸３２に装着されるときは、その途中において、当接部６１３２が被当接部に当接することで、芯本体６１は、支持軸３２に対する正規の装着位置までの移動が途中で阻止される。【選択図】図５
