Patent ID: 7708239

Claim:
A turntable comprising: a rotatable member rotatable together with a display portion about a predetermined axis line; a fixed member disposed on one side of said rotatable member in a direction of said axis line; a first friction plate whose rotation about said axis line is restricted by said rotatable member, said first friction plate being movable relative to said rotatable member in a direction along said axis line, and a second friction plate whose rotation about said axis line is restricted by said fixed member, said second friction plate being movable relative to said fixed member in a direction along said axis line, wherein said first friction plate and said second friction plate are disposed between said fixed member and said rotatable member in a direction of said axis line, and wherein, at least, a first sliding contact portion between said fixed member and said first friction plate, a second sliding contact portion between said first friction plate and said second friction plate, and a third sliding contact portion between said second friction plate and said rotatable member are provided, said first, second and third sliding contact portions respectively generating friction.
