摘要

A sliding contact type linear motion guide unit having at least one of desired anti-vibration and braking functions is provided. The unit includes a rail extending over a desired length, a slider movably mounted on the rail and a sliding member interposed between the rail and the slider. The sliding member includes an elastic member fixedly attached to the slider and a contact member fixedly attached to the elastic member and having a contact surface in sliding contact with the rail. In the preferred embodiment, the elastic member includes an elastic enclosure having therein a fill, such as a gas, liquid or gel, under pressure, so that the contact pressure between the contact member and the rail can be maintained substantially unchanged and uniformly. A control valve is preferably provided in communication with the interior of the enclosure.
