Abstract

PURPOSE: To make constitution simple and assembling easy and make possible accurate transmission of the displacement quantity of a measuring contactor to the pointer by magnifying the displacement quantity of the measuring contactor through the utilization of magnetic force and trasmitting the same to the pointer.
CONSTITUTION: When a measuring contactor 8 is contacted to the measuring object and a measuring arm 3 is turned about balls 7, 7, the magnetic poles 19, 20 held to the measuring arm 3 displace in the longitudinal direction of a revolving shaft 9. Since the magnetic poles 19, 20 and a magnetic sensing part 14 always attract to each other by magnetic force, the movement of the magnetic poles 19, 20 in the longitudinal direction of the revolving shaft 9 causes the revolving shaft 9 to revolve , thus causing the pointer 13 to rotate. Since in this way the displacement quantity of the measuring contactor 8 is magnified and transmitted to the pointer by the measuring arm 3 and the magnetic screw constituted by the magnetic poles 19, 20 and magnetic sensing part 14, the displacement quantity of the measuring contactor 8 may be accurately magnified and transmitted to the pointer with the simple constitution.
