PURPOSE:To enable foreign matters to be completely removed in a fine structure part of a guide groove, by forming liquid elastic filler in a sealing member in such a manner that it is injected into a gap provided between members and then solidified. CONSTITUTION:A gap 15 if formed between both panel member 12 and 14 by being enclosed with the opposite surfaces of both panel members 12 and 14 and the upper and side surfaces of a guide rail 1. Following this, an elastic filler material 16 is formed by into the gap 15. The urethane foam into the gap 15. The urethane foam is so solidified as to fill fine structure parts such as ball rolling groove 3 on the side of the guide rail 1 and the clearance grooves 3a of a ball holding vessel. Accordingly, the fine dust or the like which can not be cleared away by the panel member 14 can be completely removed by the elastic filler material 16.
