Disclosed is a sheet material fixing work can be easily performed in , moreover , to provide a sheet fastener which can fixed to the ground sheet material firmly . Flexible portion 3b of the second bracket 3 is placed so that apart from the sheet material 10 on the sheet material 10 to cover the A ground G. Engaging the engaging portion 2b to the engaged portion 3c and is inserted into the ground as well to the portion surrounded by the main body 3a so as to correspond to first fitting 2 to penetrate the sheet material 10 . By bending the flexible portion 3b in the insertion operation of the additional ground first fitting 2 , the main body 3a in reaction restoring force of the flexible portion 3b is fixed by pressing the sheet material 10 on the ground G. [ Selection Figure Figure 1【課題】シート材の固定作業を簡単に行うことができ、しかも、シート材の地面への固定を強固にできるシート材固定具を提供する。【解決手段】地面Gを覆うシート材10に第2金具3を可撓部3bがシート材10から離間するよう載置する。本体部3aに囲まれた部分に第1金具2を対応させてシート材10に貫通させるとともに地中に差し込んで係合部2bを被係合部3cに係合させる。第1金具2のさらなる地面への差込動作で可撓部3bを撓ませることにより、可撓部3bにおける復元力の反作用で本体部3aがシート材10を地面Gに押し付けて固定する。【選択図】図1
