Abstract:
A turntable on which a disk is loaded, said turntable comprising:a fixing portion into which a rotational shaft which rotates said turntable is pressed, said fixing portion being elastically deformable in a radial direction of said fixing portion; a reinforcer which is provided at an outer circumference of said fixing portion, said reinforcer generating reaction force against elastic deformation of said fixing portion in the radial direction, wherein said reinforcer has a reinforcing portion, which is disposed such that a space is provided between said reinforcing portion and said fixing portion, and a connecting portion, which is formed from said fixing portion to said reinforcing portion, wherein said connecting portion is a plate-shaped member which is formed radially from said fixing portion to said reinforcing portion; and a reaction force applying portion which is provided at an outer circumference of said reinforcing portion substantially perpendicularly to said turntable, said reaction force applying portion generating reaction force which opposes a force by which said reinforcing portion is elastically deformed in the radial direction of said fixing portion.
