<P>PROBLEM TO BE SOLVED: To provide a reel including such a fixing structure that a plurality of expanded resin-made members can easily and surely be fixed to one another into one body without using an adhesive. <P>SOLUTION: The fixing structure is used when the end face of an expanded resin-made side plate member 3 is fixed to the end face 4 of an expanded resin-made cylindrical core member 1 to be a reel A. A first locking body 10 which has such a slope 12 that a distance from the contact surface L of the end faces becomes longer gradually toward the turning direction and which has a recessed part 13 formed at the terminal end of the slope 12, is formed on the end face 4 of the core member 1. A second locking body 20 having a projection 23 which is fitted into the recessed part 13 formed on the first locking body 10 at the tip side thereof in the rotative direction is formed on the end face (the back surface) 7 of the side plate member 3. A distance da from the contact surface L of the end faces at right before the recessed part 13 of the slope 12 is made longer than a distance db between the upper surface 24 of the projection 23 and the contact surface L of the end faces. <P>COPYRIGHT: (C)2012,JPO&INPIT |
