PROBLEM TO BE SOLVED: To provide a lining material which is excellent in sealability with respect to granular substances at an edge part of the lining material and can reduce execution time of fitting the lining material, and a granular substance injecting machine using the lining material.SOLUTION: A lining material comprises a rubber body 1 and a fastening substrate 2 laminated on a rear face of the rubber body. The fastening substrate has one or a plurality of fastening parts 3. The fastening part comprises an engaging opening 3a into which a bolt head part Y or a nut of a bolt-nut fastening mechanism can be inserted, and a positioning slit 3b which is continuous to the engaging opening and has a width into which a bolt shaft part X of the bolt-nut fastening mechanism can be inserted and the bolt head part or the nut cannot be inserted. The engaging opening and the positioning slit are not continuous to an edge part of the fastening substrate. The positioning slit is preferably a rectangular shape having a short side length in which the bolt shaft part can be fitted, and its tip part may be a substantially semicircular shape.SELECTED DRAWING: Figure 3 |
