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.

Abstract: The present invention relates to improving precision in a gate-type moving device. The gate-type moving device includes: a base, a gate-type moving body that is placed on the base via an air layer and moves on the base in a non-contact state, and an air bearing that forms the air layer, wherein the gate-type moving body is comprised of two leg parts that stand on an upper surface of the base, a beam portion that connects the leg parts, and a beam-direction moving body that moves along the beam portion, the air bearing is provided at a rear surface of at least one of the leg parts, and comprises an air blowout port that opens toward an upper surface of the base and an air suction port that opens toward the upper surface of the base, and the air suction port sucks air around the air suction port.
