PURPOSE:To abut a roller on a side surface of a shaft surely by making at least one end portion of a pin, which bears on axis at least one roller among rollers, a small diameter portion smaller in diameter than a hole for bearing the small diameter portion in the hole via a collar member which is drilled the hole, in which said small diameter portion is fitted, in eccentric position on one end face. CONSTITUTION:In a linear motion bearing 2 three rollers 5 are journaled with pins 6, 6 and 61 and small diameter portions 61a are formed on both end parts of the pin 61. These small diameter portions 61a are supported with holes 4a bored in a body 3 via eccentric collars 7 that are collar members. Still more, pins 6 are fitted to holes in grooves 4 without using eccentric collar 7. On account of this construction, after small portions 61a of the pin 61, which journals a roller 5, are fitted to eccentric holes 7a drilled in eccentric collars 7, the eccentric collars 7 are made to rotate until the roller face of the roller 5 abuts on a side face of a shaft 8 when this bearing is assembled. Thereby, rollers 5, 5... and the shaft 8 are assembled surely in abutting condition.
