A press comprising a substrate (1), a guide body (2) having one end orthogonal to the substrate (1), a supporting plate (3) orthogonal to the guide body (2), a threaded shaft (5) supported by the supporting plate (3) parallel with the guide body (2), a nut member (8) screwed on the threaded shaft (5), and a movable body divided into first and second movable bodies (71), (72) facing each other by a plane perpendicular to the moving direction of the movable body. The first and second movable bodies (71), (72) are coupled through a differential member (27) slidably engageable with the first and second movable bodies (71), (72) while sliding. The differential member (27) is movable in the direction orthogonal to the moving direction of the movable body and the first and second movable bodies (71), (72) are moved relatively through movement of the differential member (27).
