The pointer A is attached to the magnet rotor Mg via the pointer shaft R by driving or the like. At this time, if there is an error in the attachment of the pointer A to the magnet rotor Mg, the vehicle speed indicated by the pointer A and the dial B will actually be the same. It has a drawback that it requires very careful installation work because it will be different from the vehicle speed.
