摘要

A slider slidably mounted on a guide rail has a recess formed in the lower surface of the slider, and a pressure vessel made of elastic material is accommodated in the recess. A friction plate is attached to the lower surface of the pressure vessel to abut against the upper surface of the guide rail. Hydraulic pressure is exerted on the upper surface of the guide rail through the friction plate by the pressure vessel and is adjustable by a pressure control valve so as to vary the frictional resistance between the slider and the guide rail.
