PURPOSE: To faithfully transmit the oscillation, which a stylus tip acquires, to the rear by loading a plate-shaped damper with the stylus pressure.

CONSTITUTION: Holding parts 6 whose part just above the stylus tip is joined to the upper rear face of a cantilever 2 and other part is separated from the cantilever 2 and rear part is joined to a case 5 are formed with materials having a spring property like a steel or a carbon material, and the function as a damper is given to these parts 6. The cantilever 2 is supported at two points like fulcrums 7 on the section so that the cantilever 2 can be freely moved. Since the load applied to a stylus tip 1 is supported by the plate-shaped damper 6, the oscillation from the stylus tip 1 is transmitted to the rear without distorting the cantilever 2.
