  • Turntable and display apparatus
    Patent number: 7708239
    Abstract: A turntable includes a rotatable member rotatable together with a display portion about a predetermined axis line, a fixed member disposed on one side of the rotatable member in a direction of the axis line, a first friction plate whose rotation about the axis line is restricted by the rotatable member (and movable relative to the rotatable member in a direction of the axis line), and a second friction plate whose rotation about the axis line is restricted by the fixed member (and movable relative to the fixed member in a direction of the axis line). The first friction plate and the second friction plate are disposed between the fixed member and the rotatable member in a direction of the axis line. At least, a sliding contact portion between the fixed member and the first friction plate, a sliding contact portion between the first friction plate and the second friction plate, and a sliding contact portion between the second friction plate and the rotatable member are provided.
