PURPOSE:To facilitate the formation of a ball bearing holder by forming the ball bearing holder by elastomer material. CONSTITUTION:A ball bearing holder 10 is formed by plastic elastomer material. In a mold, as shown by virtual lines on the left side, a groove shaped cut 14 opened upward can be formed by a cylindrical upper mold 22 and also a groove shaped cut 14' opened downward can be formed by a cylindrical lower mold 24 so that the mold can be simplified. At the time of disassembly, it is easily disassembled only by parting the upper mold 22 from the lower mold 24 in the vertical director so that manufacturing cost is reduced. Accordingly, the formation of the holder becomes easier than a conventional one so that mass- production becomes possible.
