Abstract: A worm biasing structure biasing a worm engaged with a worm wheel includes a radial bearing and an elastic body. The radial bearing supports the worm in a radial direction. The elastic body has elasticity and biases the radial bearing toward the worm wheel in a biasing direction. The elastic body includes a low-spring rate elastic body and a high-spring rate elastic body having a higher spring rate than that of the low-spring rate elastic body in series in the biasing direction.

Abstract: A steering apparatus includes a collision relaxation member provided on a surface of a housing, the surface being opposed to each rack end in a vehicle width direction. The collision relaxation member includes an elastic member arranged in an outer side of a rack shaft in a radial direction and absorbing a collision load from the corresponding rack end, and a shock absorbing member provided in an inner peripheral side of the elastic member and buckling by abutting of the rack end.
