摘要： In this steer-by-wire steering reaction force control device, a steering controller is provided with: a turning reaction force estimation unit configured to calculate an estimated value of a turning reaction force or a parameter representing vehicle behavior from a vehicle motion model; and a comparison unit configured to compare the estimated value calculated by the turning reaction force estimation unit with a value detected by a turning reaction force sensor, and configured to select either one of the estimated value and the detected value in accordance with a predetermined condition. Further, a steering reaction force generation unit is provided that is configured to use the estimated value or the detected value selected by the comparison unit for generation of a steering reaction force.

摘要： In a bearing device for a vehicle wheel (1), a large-diameter section (2i) is formed on an outer side of a fitting cylinder section (2h), and a small-diameter section (2j) is formed on an inner side of the fitting cylinder section (2h). A cap member (8) is formed by bending a metal steel plate, and has a cover plate section (81) which closes the inner open end of an outer member (2) and a fitting section (82) which is fitted over the small-diameter section (2j). A tapered portion (83) based on the spring back angle θ of the fitting section (82) is provided at the outer peripheral edge of the outer end section of the fitting section (82).
