PROBLEM TO BE SOLVED: To provide a spool for a long object, whose door portion can easily be switched into an opened posture or a closed posture, and can surely hold the end portion of the long object at an arbitrary position with the door portion switched into the closed posture.SOLUTION: The spool for the long object has a cylindrically formed body portion (2) and a pair of flange portions (3) extended from both the side ends of the body portion (2) on the radially outer sides, in which the winding portion (5) is formed on the periphery of the body portion (2) between both the flange portions (3). One flange portion (3a) is formed in a larger diameter than that of the other flange portion (3b), extending and disposing the ring-like door portion (7) on the outer peripheral portion (6b) of the small diameter flange portion (3b) so that the door portion (7) can be bent to switch into the closed posture (X) wherein the tip end side of the door portion (7) is displaced on the large diameter flange portion (3a) side or into the opened posture (Y) separated from the large diameter flange portion (3a). The door portion (7) is formed in a larger outer diameter than that of the large diameter flange portion (3a) so that the door portion (7) in the closed posture (X) contacts with the outer peripheral portion (6a) of the large diameter flange portion (3a) at a position inward separated from the tip end periphery (9).COPYRIGHT: (C)2010,JPO&INPIT【課題】扉部を容易に開き姿勢と閉じ姿勢とに切換できるうえ、閉じ姿勢に切換えた扉部により任意の位置で長尺体の端部を確実に保持できるようにする。【解決手段】円筒状に形成された胴部(2)と、胴部(2)の両側端から径方向外側へ延設した一対のフランジ部(3)とを備え、両フランジ部(3)間で胴部(2)の周囲に巻装部(5)を形成する。一方のフランジ部(3a)を他方のフランジ部(3b)よりも大径に形成する。小径フランジ部(3b)の外周縁部(6b)に環状の扉部(7)を延設し、扉部(7)の先端側を大径フランジ部(3a)側へ変位した閉じ姿勢(X)と大径フランジ部(3a)から離隔した開き姿勢(Y)とに切換える。扉部(7)の外径を大径フランジ部(3a)の外径よりも大きく形成する。閉じ姿勢(X)の扉部(7)を、先端周縁(9)から内方へ入り込んだ位置で大径フランジ部(3a)の外周縁部(6a)へ当接させる。【選択図】図2
