Abstract
A slide caliper of this disclosure includes: a fine adjustment measurement part including: a finger-press type rotation part; and a supporter, wherein the finger-press type rotation part includes: a roller part including two disks; and a roller shaft part, wherein at least a portion of inner surfaces of the two disks and the main scale come into contact with each other by frictional force, wherein the roller bearing part includes: an inclined surface along which the roller shaft part is movable when the measuring force is applied; and a stopper disposed at a position where the stopper and the roller shaft part come into contact with each other, and when the measuring force is applied, the frictional force with respect to the roller part is reduced as the roller shaft part moves along the inclined surface while contacting with the stopper to limit the measuring force.
