Claims

[Scope of utility model registration request]

A sliding body of a track guide bearing has a recess in which a plurality of parallel ball transfer grooves are formed in the axial direction, and a large number of balls are arranged in the ball transfer grooves so as to be able to circulate therein, and a mechanism that limits movement in the axial direction. A ball falling-off prevention device having a stop portion and a bulging portion projecting laterally, the device being fitted into a recess of the sliding body and prevented from falling off by engaging the bulging portion with the ball. A sliding body assembly for a track guide bearing, characterized in that the ball disposed in the recess of the sliding body is prevented from falling off by the ball falling-off prevention device.
