摘要

A recess (13) is formed on the outer periphery of the cylindrical body (11) of a ball bush (10). Balls (14) are rolled between the inner periphery of the cylindrical body and the periphery of a guiding rod, when the bush is inserted at the rod. The ends of the cylindrical body outer periphery are tapered.
