Abstract
Provided is a separator having excellent chemical resistance, impact resistance, and productivity. A bearing retainer (1) is a separator that is interposed between two spheres adjacent to and moving in conjunction with each other for retaining the spheres configured to be movable in conjunction with and apart from each other and is formed from a resin composition containing a fluororesin which is a polymer of a monomer containing vinylidene fluoride as a main component. The bending modulus of elasticity of the resin composition is 1600 MPa or less, and the Charpy impact strength of the resin composition is 26 kJ/m2 or more.
