PROBLEM TO BE SOLVED: To secure a desired engagement ratio and engagement strength and to make attachment and fixation to a planar attachment body rigid by intermittently forming recessed parts at the fitting edge part of a planer base part along the length direction of the fitting edge part. SOLUTION: This fixing body 1 for a sheet material is provided with the planar base part 3 provided with a length approximately same as the attachment body 2, a width dimension W approximately equal to a distance between the bottom surfaces of both fitting groove parts 2c and a thickness T approximately equal to the opening width dimension of the fitting groove parts 2c. On a surface at a center part excluding both end edge parts 3a in the width direction of the planar base part 3, many hook-like engagement elements 4 are projected and molded integrally with the planar base part 3. On the surface of an ear part 3a on a side where the hook-like engagement elements 4 are projectingly provided, the recessed parts 3a' are intermittently formed along the length direction and a continuous uneven surface is constituted. Thus, the desired engagement ratio and the engagement strength are secured and the attachment and the fixation to the planar attachment body 2 are made rigid. |
