The present invention provides a structure which reduces an axial dimension of a front end-side portion of a worm shaft in a worm reducer including a pressing means for reducing backlash at a meshing portion. The worm reducer includes a coil spring for pressing a rocking member, which is provided to be rockable about a rocking shaft, to one side in a rocking direction about the rocking shaft. The worm reducer further includes a guide member configured such that, as the rocking member rocks to the one side in the rocking direction about the rocking shaft, the worm shaft is moved in a meshing direction which is a direction in which the worm shaft comes close to a worm wheel and is pressed by the guide member in the meshing direction through a front end-side bearing for supporting a front end of the worm shaft.
