Claims

[Scope of utility model registration request]

A U-shaped bed with a raceway groove formed in the longitudinal direction of the inner and both side wall surfaces of a thin-walled member with a substantially U-shaped cross section, a raceway groove formed at a position corresponding to the raceway groove, and a ball including the raceway groove. It consists of a table on which an endless circulation path is formed, and a number of balls inserted into the endless circulation path of the table, and the balls are inserted between opposing raceway grooves to perform relative infinite linear motion. In the ball bearing for infinite linear motion, the table is fixed to a plate having substantially the same shape in which a groove having a cross-sectional shape of approximately half of the endless circulation path is formed, with the grooves aligned above and below, and the grooves of the plate are An endless circulation path of a rolling bearing for infinite linear motion, which is characterized by expanding in a substantially tapered shape from the bottom of the groove toward the top.
