To provide a linear rolling bearing generating less noise and providing high kinetic accuracy.

This linear rolling bearing 10 comprises a guide rail 14 extending in the vertical direction 12 and a guide carriage 16 guided by the guide rail 14 so as to be vertically moved by using the rolling elements 22 of at least two circulation rows. The rolling elements 22 in each row are accepted in an infinite circulation passage 24. The infinite circulation passage is formed of a support passage 26 and a return passage 28 extending in the guide carriage 16. The support passage 26 is defined by a running route 30 in the guide rail 14 and a running route 32 in the guide carriage 16. The portion 36 of the guide carriage 16 formed to be movable relative to the running route 32 is formed on the inner peripheral surface of each of the return passages 28.
