<p>PROBLEM TO BE SOLVED: To provide a cushioning material being hardly detached from a band main body.SOLUTION: A cushioning material 22 is provided with a cover section 30 being curved such that a center line CL passing a center of a thickness is convex toward a side opposite to a band main body 20 side and is integrally formed with end portion hold sections 31 formed with grooves 36 inserted with end portions 20e of a band main body 20 at both end portions of a cover section 30. The cover section 30 curved is corrected to be linear by inserting the end portions 20e of the band main body 20 into the grooves 36 and mounting the cushioning material 22 onto the band main body 20. Internal stress for causing the cover section 30 to return to an original shape curved is generated in the cover section 30 corrected to be linear, and rotational force C in a direction opposite to a direction where the band main body 20 is turned up is applied to both the end portions of the cover section 30. On this account, the cushioning material 22 is suppressed from having both the end portions turned up and being detached from band main body 20.</p> |
