Abstract
PURPOSE: To avoid the oil leakage by securing the power transmission between the driving source to drive the lift axle and the driving component provided to the lift axle by the magnetic coupling of the subordinate component provided into the viscoelastic fluid.
CONSTITUTION: Tone arm 1 is turned with turning plate 7 and moved up and down with lift arm 9 incorporating lift axle 10. Axle 10 is moved up and down with electromagnet 11. The updown movement is given by the electric conduction of coil 15 to subordinate component 16 which is connected magnetically to axle 10 via driving component 17. Component 16 is enclosed into the 2nd ring cavity 19b of container 19 along with viscoelastic fluid 21 such as the silicone oil or the like, and then sealed up hermetically with cover substance 22.
