Abstract: A receiving reel 10 comprises a receiving ratchet 11 and a detachable receiving cap 12 that is set in the receiving ratchet 11 and on which a covering tape 1c is wound, and is provided with contact members 13 and 14 that are provided on the area of engagement of the receiving cap 12 and the receiving ratchet 11. The contact members make contact in the direction of rotation and prevent the receiving cap 12 from coming loose. Mutually contacting concave and convex members 15 and 16 are provided on the contact surfaces along the direction of rotation of the contact members 13 and 14 to make it simple to detach the receiving cap 12 and to prevent it from coming loose and falling off.
