Abstract

PURPOSE: To improve sensitivity and to facilitate production by suspending a pointer with a supporting member having a small torsional regidity.
CONSTITUTION: A magnetic pointer 4 is supported by having its center sides adhered to strings 23a and 23b which are extended in parallel while having their upper and lower ends fixed between the upper and lower portions 21 and 22 of a case. As a result, the magnetic pointer 4 is supported by the small torsional rigidity of the support member of the two strings 23a and 23b while being allowed to rotate in a horizontal plane and restricted in a vertical plane. Thus, the pointer 4 can be directed in the direction of magneticism of the earth. Moreover, the clamp mechanism for the pointer 4 can be dispensed with, and it is sufficient that the pointer 4 is adhered to the strings at the spaced two points. Thus, the sensitivity can be improved, and the production can be facilitated.
