Abstract

PURPOSE: To obtain a highly reliable and inexpensive driver by tightly sealing viscous oil and a driven member in a oil tank provided with elevating winding in the center and turning winding on the outside surface.
CONSTITUTION: In oil tank 26 provided with winding 27 for elevation in the center and turning windings 29 and 30 on the internal surfac outside of it, driven member 33 provided with turning magnet 34 opposing to turning windings 29 and 30 is tightly sealed together with viscous oil. Then elevating live spindle 23 penetrating oil tank 26 in the center is coupled with driven member 33 in oil tank 26 to derive vertical power and turning force. Thus, the highly reliable and inexpensive driver for elevating and turning tone arm 1 of the record player can be obtained only by combining magnets and a fluid simply.
