ABSTRACT:
A linear motion guide unit includes a U-shaped bed, a U-shaped table turned upside down, a plurality of rolling members in a guide channel defined between the bed and the table, a retainer for retaining the rolling members in position, a pin provided at each end of the retainer and a belt provided at each end of the unit with its one end fixedly attached to the bed, its other end fixedly attached to the table and its intermediate portion passed around the pin. Thus, the retainer is moved only in synchronism with the table or bed and over a half of the distance travelled by the table or bed.
