Abstract
Device for measuring length of the type sliding caliper or height gauge, in which the guiding of the slider along the beam is ensured by at least two guide shafts engaged in grooves of the slider and in slideways of the beam. The contact surface between the guide shafts is reduced to segments of a line in order to minimize the friction and to have a guide surface in a zone protected from impacts. In a preferred embodiment, the slideways have a section corresponding to a circular segment and the part of the guide shafts engaged in the slideways a section corresponding to a segment of a circle of smaller diameter. The guide shafts are supported on the slider only at their two ends and are floating between these two points of contact. The parallelism of the fixed and mobile jaws is adjustable with the aid of a screw.
