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.

Abstract: One embodiment provides a power steering apparatus including: a worm gear that is rotated by receiving a driving force; a bearing member that supports the worm gear so as to make the worm gear rotatable; a worm wheel that is connected to the worm gear so as to be rotatable and apply a steering assist force to a steering wheel; and a support member that supports the bearing member so as to make the bearing member slidable in a crossing direction that crosses a rotating shaft of the worm wheel. The support member has a guide surface to guide the bearing member in the crossing direction therealong. The support member also has a holding portion that holds a lubricant in a recessed portion that is recessed from the guide surface.
