PURPOSE:To easily cut a wear-resistant member out of an original sheet by using heat-sensitive paste to attach the wear-resistant member to a cartridge case. CONSTITUTION:The heat-sensitive paste is applied to the single side of a wear- resistant member 19 so that the member 19 is fixed to the inner wall of a case 9. As a result, the member 19 can be easily cut out of an original sheet compared with a conventional process where an original sheet for the member 19 which is backed with a double-coated tape is cut into a due form of the member 19 with care taken to the removal of the tape. The cut member 19 is adsorbed and heated before it is fixed at a prescribed position of the case 9. In this case, the heat-sensitive paste is melted and therefore the cutting means 4 and 7 are never soiled by the paste when the member 19 is cut. |
