の磁石取付装置。A magnet fixed to the upper end of the main shaft and a rotor fixed to the pointer shaft are mounted on a frame with a predetermined gap and abutted to create magnetic coupling, and the eddy current action generated in proportion to the angular velocity of the magnet is absorbed by the elasticity of the spiral spring. In an eddy current meter that converts the rotational speed of the main shaft into angular rotation of the pointer shaft in balance with A penetrating shaft portion is formed with an outer diameter such that the penetrating shaft portion is not press-fitted, and a fixing plate is formed on the inner circumferential surface of the penetrating shaft portion with tear protrusions protruding from several places on the inner circumferential surface of the penetrating shaft portion. At the same time, a magnet is inserted into the plate, and the fixing plate is fitted, and the fixing plate is fixed to the penetrating shaft by the locking action between the cleft protrusion and the penetrating shaft, and the fixing plate and the mounting stage are connected to each other. A magnet mounting device for an eddy current type meter, characterized in that a magnet is clamped and fixed between the two.
