ABSTRACT:
The invention relates to a device for preventing a turntable for a record player from slipping off a shaft rotatably extending through a boss made of a metal fixed to the turntable. The turntable has integrally formed therewith slot means for receiving two bent ends of leg portions of a generally U-shaped retainer spring and a plurality of support projections. With the slot means and the plurality of support projections, the retainer spring is mounted to the turntable such that the leg portions thereof extend substantially in parallel to each other and across a circular axial end of the boss. The shaft is formed with a radial groove to receive the leg portions of the retainer spring. The plurality of support projections will serve as a spacer to keep the leg portions apart to prevent interference contact bwtween the leg portions and a bottom wall of the radial groove which otherwise would hamper smooth rotation of a turntable.
