A shape of an inner periphery in an axial direction of the metallic outer ring 3 has at least two portions in the axial direction to transmit a load from the metallic outer ring 3 to the resin inner ring 4. The shape can approximately uniformize contact pressure distribution in an axial direction in contact faces of the resin inner ring and the screw shaft when the load is applied to the nut in an axial cross-section of the nut, and the contact pressure distribution is acquired by analysis by a finite element method using two-dimensional axisymmetric model of the nut.
