Abstract

PURPOSE: To attain high reliability and inexpensiveness by hermetically sealing a driven member for elevating rotation and a bobbin together with viscous oil and by coupling an elevating live spindle with the driven member.
CONSTITUTION: Elevating coil 27 wound around bobbin 26 made of a magnetic material is 1 arranged in the center and then driven member 31 made of a magnetic member surrounding the outer circumference of elevating coil 27 is also arranged. Elevating live spindle 23 penetrating bobbin 26 in the center is fixed to driven member 31 and magnet 32 magnetized into poles N and S is fixed to the outer circumference of driven member 31 and hermetically sealed in oil tank 33 equipped with rotary winding 34 together with viscous oil. Elevating driving shaft 23 for ascent and descent can be applied with vertical power for elevating the tone arm and turning force for turning the tone arm.
