Claims

[Scope of utility model registration request]

A pointer shaft 29 that angularly displaces in proportion to the rotational speed of the main shaft 23;
A disc 31 is attached to the pointer shaft 29 and has a protruding part 30 with a part of its periphery protruding in a fan shape, and a oscillating member that swings in the radial direction of the disc 31 to move toward and away from the protruding part 30. It has a swinging rod 42, and the swinging rod 42 is swung by a swinging mechanism. When the swinging rod 42 comes into contact with the overhang 30, a one-point mechanism provided on the swinging rod 42 closes. In the speed alarm device for an eddy current meter, the swinging rod 42 is provided with a raised protrusion 41' that comes into contact with and separates from the periphery of the overhang 30. The tip of the protrusion 41' is cut and raised toward the pointer shaft 29 starting from the rear in the displacement direction A of the overhang 30 that is angularly displaced as the main shaft 23 rotates upward. A speed alarm device for an eddy current meter, wherein an end face 51 of the overhang 30 facing oppositely forms an acute angle α with the outer peripheral edge of the overhang 30. ′
