In the linear reciprocating rolling bearing device in which the movable element is supported by the stator so as to be capable of linear reciprocating movement relative to the stator, the first gear and the second gear rotate integrally with each other. A first rack and a second rack are rotatably supported by the stator, the second gear has a radius twice that of the first gear, and extend in the direction of linear reciprocating movement of the movable element. are fixed to the retainer and the movable element, respectively, and mesh with the first gear and the second gear, respectively. (2) The linear reciprocating rolling bearing device according to claim 1, wherein the rolling elements are steel balls or rollers. (3) A utility model characterized in that the circumferential pitches of the first gear and the second gear are equal to each other, and the ratio of the number of teeth of the first gear and the second gear is 1:2. A rolling bearing device for linear reciprocating motion according to registered claim 1 or 2.
