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.
