Abstract
A linear module includes: a base, a slide stage, two support frames, two retaining units and a steel belt. With the pivoting freedom given by the guide portions of the retaining units, when the slide stage moves, the rolling elements can be abutted more closely against the contact surface of the steel belt via the pivoting of the guide portions, so as to reduce the occurrence of deformation and clearance produced by the steel belt, which not only improves the sealing performance of the steel belt and operation smoothness of the linear module, but also produces a dust proof effect, thus achieving the purposes of automatically adjusting contact angle, preventing deformation while extending the life of the steel belt.
